PROJECT TITLE :
A Dual-Band High-Gain Resonant Cavity Antenna with a Single Layer Superstrate
In this communication, we have a tendency to present a novel style of a dual-band high-gain resonant cavity antenna (RCA) with single polarization. First of all, the speculation of twin-frequency operation of typical RCA with single superstrate is mentioned. Next, we designed a feed system, for dual-band operation with single polarization and directional patterns, two T-shape slots in nonradiating edges of the microstrip patch are introduced, which is the feed system of the designed dual-band high-gain RCA. Then, a full-wave analysis is performed to extract the impedance matching and radiation patterns of feed system and the whole RCA. At the last, measurement results are provided to compare with the modeling and simulations results which agree fairly well.
