Abstract :
In this paper, a novel method is presented for designing a dual-band dual-polarized high-gain Resonant Cavity Antennas (RCA). The design procedure is also explained. The RCA includes two layers of dipole arrays each situated at a designed height above the ground plane of a microstrip patch antenna. The lower band has a gain of 22.1 dB with the vertical polarization (pol V) at 10.1 GHz and the upper band has a gain of 16 dB with horizontal polarization (pol H) at 11.9 GHz. The cross polarization is below 37 dB at each band.
