    This paper presents a simple four ports gap coupled MIMO (multiple input multiple output) MSA (microstrip antenna) desirable for 5G, WLAN, and other modern wireless applications. The presented antenna exhibits very good input characteristics with proper isolation between the adjacent ports. An input impedance bandwidth of 39.10% was obtained from the measurements. The measured adjacent ports isolation coefficient are better than -15dB & other ports isolation is found to be nearly -20dB. The envelop correlation coefficient (ECC) value was found to be less than 0.03 which is well within the prescribed limit. The measured diversity gain (DG) was above 9.8dB in the band of interest Simulated results were compared with measured values and good matching was found between these two results.

  • A Novel Feeding Technique for Gap Coupled Suspended UWB Microstrip Antennas
    Pradeep Reddy and Veeresh G. Kasabegoudar
    IEEE
    In this work suspended microstrip antennas with a new simple feeding technique suitable for ultra-wideband (UWB) operations are presented. The antenna with the proposed feed provides a return loss (S11<-10dB) bandwidth of more than 50%. The antenna geometry presented here is fed through an SMA connector which is physically placed away from the radiator patch. The probe pin so placed away from the radiator element couples the signal to the main radiator element through capacitive means. The antenna configuration investigated here offers an impedance bandwidth of 52.83%. The corresponding value for the measured result is 52.30%. Further, the geometry investigated here offers a gain of above 5dB and nearly stable radiation patterns across the entire frequency range of operation. The proposed geometry was optimized through parametric analysis and verified with experimental results.

    The Electromagnetics Academy
    |A planar suspended multiband Yagi antenna suitable for WLAN, LTE, and 5G wireless applications has been presented. The antenna presented here has been optimized to offer operating bands ( S 11 < (cid:0) 10 dB) centered at 2.05 GHz, 2.75 GHz, 3.8 GHz, and 6.5 GHz. The proposed antenna has good front to back (F/B) ratios of 14 dB, 13 dB, 12 dB, and 19 dB corresponding to four resonant frequencies. Similarly, the corresponding gain values are 2 dB, 1.3 dB, 3.1 dB, and 3.3 dB. A prototype antenna was fabricated and tested. Except the (cid:12)rst resonance which is a single frequency, the other three operating bands offer impedance bandwidths of 3.98% (2.71 GHz{2.82 GHz), 5.48% (3.73 GHz{3.94 GHz), and 19.27% (5.93 GHz{7.195 GHz). Measured results agree fairly with the simulated characteristics of the proposed antenna.

  • A Review of Low Profile Single Layer Microstrip Antennas
    Veeresh G. Kasabegoudar, , and Pradeep Reddy
    EJournal Publishing
    The modern wireless systems call for integrating multiple applications. There are numerous techniques available to cater these demands. However the need for thin, light weight and compact wireless applications call for the design of low profile and single layer antennas with multiple features. Hence, this paper deliberates on the comprehensive review of compact, low profile, and single layer microstrip antennas suitable for fifth generation (5G) wireless applications, wireless local area network (WLAN), worldwide interoperability for microwave access (Wi-Max), and other state of the art wireless applications. The techniques discussed here consider the performance improvement of one or more parameters of the antenna. These parameters include the improvement of impedance (10dB return loss) bandwidth, gain, 3dB axial ratio (AR) bandwidth, improvement of isolation between the ports in multiple input multiple output (MIMO) antennas, and excitation of dual modes/dual polarization/circular polarization. Antennas with all such techniques and their advantages, applications &amp; limitations have been discussed in detail. The studies presented here on single layer planar antennas offer a maximum impedance bandwidth of up to 68%, highest axial ratio bandwidth of 46%, and 11.6dBi gain for single element &amp; 25.6dBi gain for arrays. Other significant findings covered are antennas with triple bands operation, arrays with less than -37.5dB mutual coupling and compact antennas with more than 60% reduction in physical area. In addition to the advantages and applications, their limitations and drawbacks are also discussed.

  • Suspended rectangular and circular broadband patch antennas for circular polarization
    Ajit Kumar and Veeresh G. Kasabegoudar
    IEEE
    In this paper we present a suspended rectangular and circular patch circularly polarized (CP) microstrip antenna with coplanar capacitive feed. Of the two circularly polarized (CP) antennas presented here, the first antenna uses fractal geometry with center slot within the rectangular patch and other having two perpendicular slots etched on circular patch in order to get circular polarization. The first antenna has an axial ratio bandwidth (<; 3dB) of 7.1% and a much higher impedance bandwidth of about 49% (S11<;-10 dB) and also yields return loss better than -15dB in the useful range of circular polarization. After presenting the first geometry we proposed the second geometry (circular patch) which has simple geometry as compared to first geometry (fractal rectangular patch), which also offers circular polarization, with axial ratio bandwidth (AR <; 3dB) of 7.85% and also the geometry having high impedance bandwidth similar to first geometry of 53% (S11<;-10 dB) and S11 is well below -20 dB in range of CP operation. Measured values fairly agree with the simulated results.

  • Dual band coplanar capacitive coupled microstrip antennas with and without air gap for wireless applications
    Veeresh G. Kasabegoudar and Ajit Kumar
    The Electromagnetics Academy
    This article presents the coplanar capacitive coupled probe fed microstrip antennas for dual frequency band operation. The proposed antenna is excited by a single probe feed connected to a capacitive strip. Of the two dual band antennas presented here, the flrst one uses small air gap and the other is designed without air gap. In the flrst case an efiort has been made to reduce the height of suspended antenna. A vertical slot is placed to obtain antenna resonance at low frequency side, and also for proper impedance matching. After presenting the basic geometry the second conflguration (which uses no air gap) which also ofiers dual band operation at the expense of reduced bandwidth is presented. Measured values fairly agree with the simulated results.

  • Low profile suspended microstrip antennas for wideband applications
    V. G. Kasabegoudar
    Informa UK Limited
    In this paper, design of a coplanar capacitive coupled probe fed microstrip antenna suspended above the ground plane is presented. It is demonstrated that the proposed approach can be used for designing suspended microstrip antennas with impedance bandwidth of about 50% and a good gain to operate in various microwave bands. The bandwidth improvement achieved is from the well-known fact that air gap reduces the effective dielectric constant close to unity and increases the thickness of the mixed substrate. However, suspended configurations increase the overall height/volume of the antenna which limits the use of these antennas in compact applications. Therefore, in this work an effort has been made to reduce the overall height (about 55 to 73% keeping adequate impedance bandwidth (> 30%)) of the antenna significantly which is one of the key of design aspects of compact wideband antennas. It is demonstrated that the gain and radiation patterns of the proposed low profile antenna remain nearly unchanged.

  • Dual frequency ring antennas with coplanar capacitive feed
    Veeresh G. Kasabegoudar
    The Electromagnetics Academy
    In this paper, design of a coplanar capacitive coupled probe fed microstrip ring antenna for dual frequency operation is presented. The proposed antenna is excited by a single probe feed connected to a capacitive feed strip placed along one of the radiating edges of the ring antenna. The coplanar capacitive feed strip is modifled to obtain the best possible match with the antenna input impedance and to tune out the excessive capacitive reactance due to feed strip. It is also demonstrated that the modifled feed strip can be placed either inside or outside the ring and similar radiation characteristics can be obtained at both the resonant frequencies. Ring dimensions decide the resonant frequencies values and their separation. Measured data fairly agree with the simulated characteristics.

  • Coplanar capacitively coupled probe fed microstrip antennas for wideband applications
    Veeresh G. Kasabegoudar and K. J. Vinoy
    Institute of Electrical and Electronics Engineers (IEEE)
    The design and analysis of a coplanar capacitive fed microstrip antenna suspended above the ground plane is presented. It is demonstrated that the proposed approach can be used for designing antennas with impedance bandwidth of about 50% and a good gain to operate in various microwave bands. The model of the antenna incorporates the capacitive feed strip which is fed by a coaxial probe using equivalent circuit approach, and matches simulation and experimental results. The capacitive feed strip used here is basically a rectangular microstrip capacitor formed from a truncated microstrip transmission line and all its open ends are represented by terminal or edge capacitances. The error analysis was carried out for validity of the model for different design parameters. The antenna configuration can be used where unidirectional radiation patterns are required over a wide bandwidth.

  • A broadband suspended microstrip antenna for circular polarization
    Veeresh G. Kasabegoudar and Kalarickaparambil Joseph Vinoy
    The Electromagnetics Academy
    In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3 dB) of 7.1%. The proposed antenna exhibits a much higher impedance bandwidth of about 49% (S11 < -10 dB) and also yields return loss better than -15 dB in the useful range of circular polarization. Measured characteristics of the antenna are in good agreement with the simulated results. The radiation patterns indicate good cross polarization rejection and low back lobe radiations. The design proposed here can be scaled to any frequency of interest.
