Abstract
A wideband differential Fabry-Perot cavity antenna (FPCA) is presented. Unlike the mostly used patch antennas, a rectangular dielectric resonator antenna (DRA) has been investigated as primary radiation source. A compact partially reflective surface (PRS) is proposed and used as superstrate layer over the DRA for wideband gain enhancement. Measurements show that the antenna exhibits a wide impedance bandwidth (for |S11|
