摘要

A novel dual-band high-gain resonant cavity antenna (RCA) with orthogonal polarisation is presented. The RCA includes a single-layer single-sided superstrate of printed slotted patches located at a designated height above the ground plane of a microstrip patch antenna. The lower band has a measured gain of 18.06 dBi with the vertical polarisation (V-pol) at 10.25 GHz and the upper band has a gain of 19.41 dBi with horizontal polarisation (H-pol) at 11.05 GHz. The cross-polarisation (X-pol) is better than -26 dB at each band. The two bands are controlled arbitrarily and independently. To demonstrate it, two RCAs have been designed with band separation of 3.95 and 5.75 GHz.
