Abstract

In this paper, we study performance of a simple electromagnetic band gap (EBG) resonator antenna (ERA) that has a composite all-dielectric superstructure and is excited by a small sparse array. The cavity of the antenna is excited by a 2×2 array of waveguide fed slots with an inter-element spacing of 1.8λo. The ERA exhibits high gain with an excellent directivity bandwidth of around 20%. The proposed configuration provides improved performance in terms of antenna gain and directivity bandwidth, while significantly minimizing design complexity. Numerical results are presented and a peak gain of 21 dBi is demonstrated.
