Abstract :
The broadband Fabry-Perot (FP) resonator antenna composed of single-layer quasi-periodic FSS superstrate with tapered size square patch fed by U-slotted patch is proposed, whose common bandwidth for -3 dB directivity-drop and -10 dB returned loss increases by 7.99% to 12.2% for two different cases, as compared to that of previously single layer uniform FSS. Furthermore, FP resonator antenna can be regarded as a kind of EBG resonator antenna with defect mode by inserting irregular components in the periodic structure. In this paper, in vertical plane a dual-resonator 1-D EBG material incorporating with quasi-periodic printed FSS in transverse plane as reflective covered plate is also presented. It is indicated that the performance of FP resonator antenna can be further improved obviously.
