A Large Bandwidth T-shaped Microstrip-fed Ground Plane … In a conventional microstripline-fed slot antenna, a narrow rectangular slot is cut in the ground plane, and the slot is excited by a microstrip feedline with either a short 4 or an open 5 termination. With this feed configuration, a good impedance match has been achieved for a narrow slot, and an impedance...

Design and experimental verification of dual-Fed, self Design and experimental verification of dual-Fed, self-diplexed cavity-backed slot antenna using HMSIW technique -based cavity, loaded with a slot and microstrip feedlines. A radiating slot is etched on the upper metal cladding of the HMSIW cavity which splits the cavity into two sections. ... By finely tuning the antenna dimensions, a very ...
Microstrip‐fed slot antennas backed by a very thin cavity ...
superstrate-covered cavity-backed slot antenna as described in [16{21] was between 9.8 and 16.7dB. In this paper, a simple backed slot antenna with regular one single-layer superstrate is introduced. The gain is improved by modifying the ground plane orientation, adding a small number of square mushroom cells to suppress side radiation, and ...
