چکیده انگلیسی
In this paper, we propose an aperture type frequency selective surface (FSS) by employing an array of 12Â ÃÂ 12 unit cell elements and its resonant characteristics is analyzed. A resonant cavity antenna is then formed by the ground plane substrate and the FSS superstrate. The high reflective behavior of the proposed FSS at an offset of the resonance is then utilized for improving the performance of this cavity antenna. The impedance bandwidth and directivity are improved up to 0.66Â GHz and 8.95Â dBi, simultaneously at an optimum gap of 17.6Â mm between the antenna substrate and FSS superstrate. For validation purpose, prototypes of both patch antenna and FSS, are fabricated and characterized. A fairly good agreement is achieved between the measured and simulated results.
