Abstract
A single-feed high-gain EBG resonator antenna with extremely wideband performance is presented. The bandwidth is enhanced through a novel composite superstrate made from a combination of unprinted dielectric slabs with uniform thickness. The composite superstrate leads to wide defect-mode bandwidth and offers slowly increasing reflection phase profile over a wide frequency band. A single slot is used to excite the cavity. Peak antenna gain of 17.17 dBi with half-power gain bandwidth of 33.9% centered at 12.6 GHz is predicted. More than 100% increase in 3-dB directivity bandwidth with 55% reduction in aperture size is obtained as compared to conventional designs.
