A Novel Quadrangular Slotted DGS with a Wideband Monopole Radiator for Fifth-Generation Sub-6 GHz Mid-Band Applications Idrish Shaik, Sahukara Krishna Veni Progress in Electromagnetics Research C, 2023 The demand for high data rate, good channel capacity, and reliability is always the primary area of concern in the modern era of wireless communication systems. The 5G standards have the fortitude to bring about rapid data transfer speeds, instantaneous connectivity, large data capacities, and minimal latency. In this paper, a novel quadrangular slotted defected ground structure (QSDGS) that incorporates a wide band microstrip antenna (WMA) was proposed for 5G n46/n47/n79 and n102 band applications. The DGS was represented on the ground plane by four rectangular looped slots. An inset feeding technique was employed on this slotted patch antenna. This DGS loaded patch antenna structure was mounted on an RT Duriod 5880 ( r = 2.2, loss tangent = 0.0009) with dimensions of 33 29 1.5 mm 3 (0.44 0.38 0.02, where '' is calculated at the lowest operating wavelength). This embedded antenna radiating structure resonated in a wide band ranging from 4.03 GHz to 6.32 GHz giving an impedance bandwidth of 2.3 GHz (50%), with a centre frequency of 4.44 GHz. The maximum gain was 4.7 dBi, and greater than 75% efficiency was obtained over the wide band. From the results extracted from the proposed antenna, it was found that the antenna was capable of covering the 5G NR n46/n47/n79 and n102 bands with significant bandwidth, gain, and efficiency. Thus, the antenna can be considered a potential contender for 5G mid-band wireless communication systems.
A Compact Dual-Band Octal Patch Loaded with Bow-Tie Parasitic MIMO Antenna Design for 5G mm-Wave Wireless Communication Idrish Shaik, Sahukara Krishna Veni Progress in Electromagnetics Research C, 2023 In the present era of wireless communication networks, the key area of concern is always the need for faster data rates to meet the growing requirements. The 5G standards have the fortitude to bring about rapid data transfer speeds, instantaneous connectivity, large data capacities, and minimal latency. In this paper, a novel octal patch integrated with a bow-tie parasitic antenna element with full ground plane that incorporates a microstrip dual band antenna was proposed for 5G n257/n261/n259 and n260 band applications. This bow-tie parasitic antenna element integrated octal patch single and MIMO antenna structure was mounted on an RT Duriod 5880 ( r = 2.2, loss tangent = 0.0009) with dimensions of 7.5 9.9 0.9 mm 3 and 7.5 19.8 0.9 mm 3 (0.67 1.75 0.07, where is considered at the lowest operating tuned frequency). A decoupling element was precisely placed in the core of a two-element MIMO antenna to reduce the mutual coupling. This embedded antenna radiating structure resonated in dual bands ranging 26. GHz with a center frequency of 28 GHz and 40.2 GHz, respectively. This achieves a bandwidth of 2.85 GHz (10.3%) and 4.29 GHz (10.75%) at the dual bands. The maximum gains were 7.9 dBi and 6.97 dBi, and greater than 92% efficiency was obtained over the dual bands. From the results extracted from the proposed antenna, it was found that the antenna is capable of covering the 5G NR n257/n261/n259 and n260 bands with significant bandwidth, gain, isolation, ECC, DG, TARC, multiplexing efficiency, CCL MEG, and radiation efficiency. Thus, the antenna can be considered a potential contender for 5G millimeter wave wireless communication systems.
A High-Gain and Dual-band MSPA 1x2 array for 5G n78/n79 Sub-6GHz Cellular applications Idrish Shaik, Krishna Veni Sahukara Vitecon 2023 2nd IEEE International Conference on Vision Towards Emerging Trends in Communication and Networking Technologies Proceedings, 2023 In this article, the simulation and design of the simple 1×2 MSPA array was designed for use in the 5G mid bands n78/n79 are provided with L-Slots on left and right side of patch elements with dimensions of 35×52×1.5mm3. The RT Duriod/Rogers 5870(εr =2.33) was used to manufacture this antenna model and it was designed by using CST Studio suite 2019 EM solver. The L slot cut 1×2 array gives radiation efficiency of 91 % and 82% resonating at 3.448GHz and 4.728 GHz with maximum gains of 9.56dBi and 6.88dBi and also the realized gain is 8.93dBi and 6.1 dBi. Because of high gain and maximum radiation efficiency, this model can be used in broadband applications of C-band n78 and n79 5G mid bands which consist of narrow channel bandwidth.
