“…Bandwidth Improvement of Microstrip Patch Antenna using Partial Ground Plane is studied here. The overall size of the Antenna is 32.92 x 39.93 x 1.5mm 3 and it gave a Bandwidth of 230 MHz. The proposed antenna's ground plane was varied as x = 15 mm and y = 39.92 mm, it gave a Bandwidth of 400 MHz, showing an increase in the value of Bandwidth.…”

Microstrip patch antennas are of high demand for its light weight, cheap manufacturing, small size, high gain, high directive gain and also offers circular polarization apart from linear polarization. But it also has narrow bandwidth operation due to its resonant nature, which is a disadvantage for its class. Huge research is being conducted on it for its possible improvement in its performance in the near future. A large number of methods have been suggested, which can reduce the limitations of the antenna, thus improving the performance, with no deviations in the basic advantages of the antenna. The area of research interests are like changing the geometrical dimensions of the antenna, especially changing the dimensions of the ground plane of the antenna. This paper provides a comparison of the work done, by changing the ground plane to partial ground plane and getting an enhanced bandwidth value.

“…In addition, to reduce the total width of the antenna, rectangular patch‐shaped top loading is used on all the elements, and tapered transitions are used between the top loading patches and CPS lines. The optimized design parameters are as follows : l 1 = 64.2, l 2 = 48.1, l g = 77.1, s 1 = s 2 = 36, w s = 1.7, l 1t = 15.4, w 1t = 18, l 2t = 11.6, w 2t = 13.5, l gt = 20, w gt = 21.8, y f = 20, w f = 3, and w f2 = 6. The total width l g of the proposed antenna is reduced by approximately 14.3% compared to the conventional one.…”

A broadband compact series‐fed dipole pair (SDP) antenna using a simplified integrated balun is presented. The proposed integrated balun is simple compared to a conventional balun and consists of a microstrip line inserted on a coplanar strip (CPS) line, along the center of the CPS. When the proposed balun is incorporated into the SDP antenna, it creates an additional resonance due to a slot in the CPS line at high frequency as well as two resonances by the two dipoles with different lengths, and enhances the antenna's bandwidth. The proposed antenna exhibits a measured impedance bandwidth of 58.5% (1.62–2.96 GHz) for a VSWR < 2, a stable gain of 6.1 ± 0.5 dBi, and a front‐to‐back ratio > 14 dB within the bandwidth. © 2014 Wiley Periodicals, Inc.

“…Printed log‐periodic dipole array (PLPDA) antennas have now been frequently used in wireless communication applications because of their simple structures and ease of manufacturing. Moreover, they have very large bandwidth and good gain stability across the entire frequency band . This candidate antenna is highly recommended for wideband and high‐gain applications.…”

In this article, a V-band printed log-periodic dipole array (PLPDA) antenna with high gain is proposed. The antenna prototype is designed, simulated, fabricated, and tested. Simulation results show that this antenna can operate from 42 to 82 GHz with a fractional impedance bandwidth of 64.5% covering the whole V-band (50-75 GHz). The antenna has a measured impedance matching bandwidth that starts from 42 to beyond 65 GHz with good agreement between the experimental and simulated results. At 50 and 65 GHz, the antenna has a measured gain of 10.45 and 10.28 dBi, respectively, with a gain variation of 2.6 dBi across the measured frequency range. The antenna prototype exhibits also stable radiation patterns over the operating band. It achieves side-lobe suppression better than 17.26 dB in the H-plane and better than 8.95 dB in the E-plane, respectively. In addition, the cross-polarization component is 18.5 dB lower than the copolarization with front-to-back ratio lower than 24.1 dB in both E-and H-planes across the desired frequency range. Based on a comparison of performance among the reported work in the literature, we can say that the proposed PLPDA antenna is a proper candidate to be used in many applications at V-band frequency.
