High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems. A number of enhancement techniques for antenna gain have been studied –.To realize enhanced-gain performance, a cavity-backed slot antenna (CBSA) is employed in this study because of its unidirectional characteristic. Printed Wide-Slot Antenna Design with Bandwidth and Gain To increase the gain, four L-shaped slots are etched in the ground plane. The measured results show that the proposed structure retains a wide impedance bandwidth of 88.07%, which is 20% better than the reference antenna. The average gain is also increased, which is about 4.17 dBi with a stable radiation pattern in the entire operating band. MULTI-SLOTTED MICROSTRIP PATCH ANTENNA FOR … There are several well-known methods to increase the bandwidth of patch antennas, such as the use of thick substrate, cutting a resonant slot inside the patch, the use of a low dielectric substrate, multi-resonator stack conflgurations, the use of various impedance matching and feeding techniques, and the use of slot antenna geometry [4{6].

The configuration of the initial antenna with dimensions of 28 × 32 mm2 is shown in [14]. The bandwidth of that antenna is from 5.3 to 8.5 GHz for |S11| < -10 dB and the gain is generally above 4 dB with the peak of 7.2 dB. In the work reported this paper, three improvements were made.

increase in gain for the extra material and effort on 2m, but I've used 8 elements on 70cm. I have tried several ways to increase the spacing, but MMANA-GAL does not indicate any advantage. I have recently tried a simulation of 70cm inside a 2m skeleton slot with MMANA-GAL, and there is little interference with either pattern or impedance.
