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.

Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. Compact wideband cavity-backed slot antenna | SpringerLink A wideband cavity-backed slot antenna operated in the ultra-high frequency (UHF) band is introduced. The antenna has a compact structure and low profile with the size ratio of the ground plane to the slot only 1.6:1. The measured impedance bandwidth of VSWR⩽3 achieves 85.3%, covering a frequency range from 390 MHz to 970 MHz.
