摘要：
A new kind of aperture-coupled microstrip antenna with enhanced gain and radiation pattern is presented in this letter. By substituting the corrugated ground plane for the flat ground plane of conventional aperture-coupled microstrip antenna, the proposed antenna with high performance is obtained by the constructive superposition of the electric fields radiated by the patch and grooves. Both the simulation and measurement show that compared to the conventional antenna, the gain is increased by 5.3 dB, the front-to-back ratio (F/B) is increased by 6 dB, and the half-power beamwidth (HPBW) of E-plane is reduced by 125 degrees. Moreover, the proposed antenna features its compactness.
