Abstract

We present the application of artificial magnetic conductor (AMC) ground planes to low-profile resonant cavity antennas. Our novel high-gain microstrip patch antenna has a partially reflective surface (PRS) superstrate and an AMC is utilised as ground plane to reduce the antenna profile. The antenna is studied using a resonant cavity model with the microstrip patch source internal to the cavity. The antennas are formed by the ground plane and a metallodielectric electromagnetic band gap (MEBG) array that acts as a PRS. The profile of the antenna is reduced to half by virtue of employing the AMC ground plane instead of a PEC one.
