Abstract

This paper presents a high-gain cavity resonant antenna (CRA), consisting of an FSS layer placed above an aperture coupled microstrip patch antenna (ACMPA). Geometry of the proposed FSS superstrate is highly reflective with |Γ>0.9|. Ray-tracing method has been employed for determining the resonant condition of the antenna. ACMPA operating at S-band is serving as a feeding source. The coupling aperture of the antenna is of novel design, and several figures of merit have been presented for the proposed coupling aperture. Analysis of CRA has been carried out with the design parameters of the CRA. HFSS-13 has been utilized as simulation tool. Measured results are in good agreement with the simulated ones.
