Abstract The advancement in wireless communication is fueling the growth of innovative antenna array designs toward cost-effective and performance-oriented solutions. This paper proposed unconventional methods to design antenna arrays for multi-pattern synthesis without using attenuators or phase shifters. A low-cost alternative is proposed with “Time-modulation”-based antenna array capable of electronic scanning and beam steering. Here, “Time” is utilized as a fourth-dimensional (4D) array parameter, and that is why “Time-modulated” arrays are also called as 4D antenna arrays. The idea is to control the high-speed switch attached with each antenna periodically to produce desirable current and phase tapering. This article expanded the “Time-modulation” concept to synthesize multiple radiation patterns like monopulse patterns, scanned beam patterns, shaped beam patterns, and cosecant-squared beam patterns for multifunctional radar systems. Suitable time schemes are developed to generate the narrowband sum–difference patterns useful for monopulse radars. Simultaneous scanned beam patterns are also proposed for narrowband communication. Furthermore, to address the wideband applications, shaped flat-top beam patterns and cosecant-squared beam patterns are also proposed. In this regard, 20- and 16-element “Time-modulated” linear array antennas are developed, and the parameters of the arrays are controlled by suitably designed objective functions with quasi-Newton method (QNM)-based memetic optimization method. For this purpose, first a well-known genetic algorithm is adopted to search the potential trust regions in the exploration stage and QNM is used for fine-tuning. Furthermore, the Broyden’s good method-based direction-updating equation is used with QNM to improve the performance.

In modern mobile communication, it is important to provide finer as well as productive facility to all the mobile users through improved communication system. In this paper, binary phase shift key (BPSK) modulation is utilized by almost all base stations for their operation to send/receive voice/data over long distance. BPSK modulation technique is one of the efficient modulations in terms of power which requires minimum power during their operation. In this paper, the performance of mobile communication system has been compared over Rayleigh and Rician fading channel in terms of bit error rate (BER). During the transmission of information first Rayleigh fading channel has been considered and then after Rician fading channel to see the effects. The simulation of analytical expression has been performed to determine the BER over these two channels and obtained results has been shown between the BER and transmitted power of the signal. These results show BER response against transmitted power over Rician channel is better as compared with Rayleigh fading channel. Analytical results are verified by using MATLAB simulation.

Intrinsic advantages of direct sequence spread spectrum (DSSS) are interference free, multiple access, and low probability of intercept (LPI), as well as the ease with which it may be deployed, make it a suitable transmission system for both defence and commercial applications. DSSS is a standard mechanism used by the majority of current remote control devices to transfer command and control data. Only DSSS technology might not be sufficient to convey numerous accesses as soon as the multiple users of aircraft to control cultivate. To attain an efficient multiple access, a hybrid technique should be used in combination of DSSS with time division multiple accesses (TDMA) as an alternative multiple access strategy. The Bit Error Rate (BER) performance for unmanned aerial vehicles (UAV) communication has been analysed over adaptive white Gaussian noise (AWGN) channel and Rayleigh faded channel by varying number of UAVs.

Non-Orthogonal multiple access (NOMA) scheme serves as a favorable technology for 5G and beyond cellular networks as compared to orthogonal multiple access (OMA) scheme. Multipath fading also affects the performance of wireless communication system. So as to exploit the features of NOMA technique, it is vital to identify and analyze its performance over various fading channels. This paper provides the performance analysis of NOMA based cellular system over two key parameters named as channel capacity and outage probability. Rician fading distribution has been considered for multipath fading. Rician fading channel is much suitable when at least one communication link fallow a line-of-sight (LoS) path and the signal strength is much stronger than other paths. An analytical expression for channel capacity and outage probability has been derived for considered system model. Mante Carlo simulation has been performed to obtain the simulation results for channel capacity and outage probability using the Rician fading channel. Comparison of simulation results for near and far users have been provided for channel capacity and outage probability.

Device-to-device (D2D) communication is observed as an emerging technique to offload the traffic from base station for improving the network performance. Outage probability (OP) and ergodic channel capacity (ECC) are the key performance metrics for wireless communication system. This paper mainly focuses on deriving the expressions of OP and the ECC for underlay D2D communication operating over $$\\kappa -\\mu$$ shadowed fading channels with arbitrary fading and shadowing parameters by utilizing stochastic geometry. The uplink radio resource of existing cellular network has been reused by D2D users. The $$\\kappa -\\mu$$ shadowed fading is a composite channel model of multipath fading and shadowing which contains many classical fading models as special cases. The signal of interest and interfering signals both follow the distribution of $$\\kappa -\\mu$$ fading with shadowing. The analytical expressions of OP and ECC can be expressed in terms of Appell’s function and Gauss’s hypergeometric function, which makes numerical evaluation easy. Finally, the results obtained from the analytical analysis are validated through Monte-Carlo simulations that show the good agreement.

Device-to-Device (D2D) communication allows two mobile users to communicate straight way with each other. D2D communication that underlay conventional cellular networks has been recognized as a novel approach to alleviate the outage performance and ameliorate the throughput of the traditional cellular system. The co-channel interference is the major weakness of D2D communication in D2D based cellular system. The purpose of this paper is to derive the expression of D2D link outage probability (OP) for D2D based cellular system by utilizing stochastic geometry and to evaluate the achievement of existing cellular system. The Rayleigh fading, and Nakagami-m fading have been considered for the co-channel interference signals and desired signal, respectively. Expression of OP is derived and presented in terms of the Gauss hypergeometric function. This analysis acknowledge the influence of main system parameters on outage performance of the network. Results show the D2D outage probability is depends on SIR threshold, D2D pair distance, path-loss exponent, and fading parameter m. Finally, the results obtained from numerical analysis are corroborate through Monte-Carlo simulations which may gives the guidelines for network designer.

Device-to-device (D2D) communication is an emerging technique for future cellular networks to extend the network coverage. In D2D communication, two nearby mobile users can communicate directly without involving the base-station by sharing the uplink/downlink resource with cellular users. The performance of wireless communication deteriorates due to multipath fading and shadowing. Two generalized fading distributions namely $$\\kappa -\\mu$$κ-μ and $$\\eta -\\mu$$η-μ have been proposed to characterize the line-of-sight and non-line-of-sight propagation effects respectively. In this paper, the expression of coverage probability for D2D communication, when D2D direct link undergoes $$\\kappa -\\mu$$κ-μ fading with random values of $$\\kappa$$κ and $$\\mu$$μ, and interferers undergo $$\\eta -\\mu$$η-μ fading with random values of $$\\eta$$η and $$\\mu$$μ has been derived. The stochastic geometry has been utilized to derive the expression of D2D coverage probability. The Lauricella’s function, a special mathematical function has been used to represent the expression of D2D coverage probability which is easy to calculate numerically. The effects of fading parameters over coverage probability have been analyzed. Further, using the properties of Lauricella’s function and particular values of fading parameters, D2D coverage probability expression has been simplified for four special cases. The D2D coverage probability results obtained from the analytical analysis have been validated through Monte-Carlo simulation.

Unlike conventional cellular communication, device-to-device (D2D) communication establish the direct link between two nearby mobile users without involving the network infrastructure to meet the demand of high data rate and low power consumption. To incorporate the issues of power consumption, the D2D communication has been integrated with cellular networks in underlay mode. In underlay D2D communication, licensed frequency bands are utilized by both cellular and D2D communication and it may interfere with each other depends on resource sharing which affect the Quality of Service (QoS) but increases the spectral efficiency. In this paper, the average sum rate (ASR) and energy efficiency (EE) has been analyzed for D2D communication underlaid cellular networks over Nakagami-m fading channels. Both ASR and EE are the important metric for evaluating the performance of a wireless communication system. The derived expressions show the variation over D2D users density. The analytical results are validated through simulation.

Device-to-Device (D2D) communication has been recognized as one of the key technologies to improve the data rate and reduce the power consumption. In D2D communication, two nearby mobile users establishes the direct link for communication without involving the network infrastructure. A wireless communication with high data rate increases the energy consumption and greenhouse gas emission. To resolve these issues, the D2D communication underlaid cellular network over Nakagami-$m$ fading has been proposed in this paper. In underlaid in-band D2D communication, the licensed frequency bands of cellular network are reused by D2D communication. This introduces additional interference that affect the quality of service but increases the spectral efficiency with low power consumption. The D2D users transmit to their paired receiver by reusing the uplink resource of the cellular network. Average sum rate (ASR) and energy efficiency (EE) have been analyzed for D2D communication underlaid cellular networks. The poisson point process (PPP) and stochastic geometry have been utilized to characterize the random distribution of user equipment. The expressions derived for ASR and EE show the variation over cellular to BS distance, D2D pair distance, and Nakagami fading parameter. The results from this analysis provide a desirable system design parameters that offer the best gains in terms of ASR and EE.

In early days breast cancer detection is of crucial importance. Breast cancer is a serious threat worldwide and is the number two killer of women in the USA. Microstrip patch antenna, due to its various advantages i.e. small size, light weight, low profile, and low manufacturing cost, is finding increasing applications in the medical industry. In this paper, we elaborate microstrip patch antenna with technical specification and its application for breast cancer tumour detection. The key to successful management is screening and early detection. What follow is a description of the state of the art in screening and detection for breast cancer as well as a discussion of new and emerging technologies. The only way today to find out for sure if a breast lump or abnormal tissue is cancer is by having a biopsy: a suspicious tissue is removed by a surgical excision or needle biopsy and is examined under a microscope by a pathologist who makes the diagnosis. Imaging techniques of the breast are therefore vital since they will allow early detection of cancer and localisation of the suspicious lesion in the breast for a biopsy procedure.

In this paper a small antenna is proposed for wireless sensor network applications in the frequency band of 5 GHz to 15 GHz. Wireless Sensor Networks (WSN) is having significant attention due to their numerous features nowadays. The most important component in sensor is its TX/RX antenna. In this design a new efficient CRLH based DNG metamaterial antenna is proposed. The design of the unit cell of these antennas is based on the composite right/left-handed (CRLH) transmission line model. Antenna1 used two patches and obtained results are compared with antenna2 with four patch. In this paper, we introduce a new method of design of CRLH metamaterial antennas to tackle the above problem using CRLH mushroom structure. The results of antenna2 show improvements over antenna1 in gain and bandwidth. By employing CRLH geometry, an overall size reduction of 65% was achieved compared to the conventional rectangular patch antenna. The proposed antenna can be easily built in a miniaturized wireless sensor network (WSN). RogersRT/Duroid 5880 is taken as substrate with thickness 1.572 mm and relative permittivity 2.2. The bandwidth of this antenna less than 10 dB is 700 MHz and the percentage of the bandwidth is 6.1%.

In this paper, a compact multiband microstrip patch antenna with Z-shaped slots in the radiating patch is proposed. The antenna has a rectangular radiating patch on the top of the substrate and a ground plane on the bottom of it. A coaxial probe feeding is located along the orthogonal axis of the square patch radiator. Z-shaped slot on radiating patch gives a wider bandwidth with better return-loss. Various slots of this antenna are compared, and an optimized design is presented. Exploitation of Z-shape slot in antenna design makes the patch antenna flexible in terms of generating resonances and bandwidth as an order of the slots is increased. Several properties of the antenna such as impedance bandwidth, VSWR are presented.

A reduced-size wideband single-feed circularly polarized microstrip patch antenna is presented for telemetry applications in S-band around 2.4 GHz. In this paper we compare the performance of microstrip patch antenna designed over two layer conventional substrate with different relative permittivity and different height and over a Reactive Impedance Substrate with slot, both of them being constituted with the same substrate layers. In particular we optimize the feeding position and number of reactive elements upon the antenna bandwidth and axial ratio. The proposed structure consists of a slot-loaded patch antenna printed over an optimized metamaterial-inspired reactive impedance substrate (RIS). We demonstrate, step by step, the main role of each antenna element by comparing numerically the performance of various antenna configurations, antenna over a single layer substrate or dual-layer substrate, patch without slot or slot-loaded patch, antenna with or without RIS. The final optimized structure exhibits an axial-ratio bandwidth of about 15% and an impedance bandwidth better than 10%, which is much wider than the conventional printed antenna on the same materials. The return loss pattern of different microstrip patch antenna with and without RIS arrangement is also compared using HFSS simulation software.
