Abstract :
A new design of compact EBG resonator antenna to improve a directivity is introduced in this paper. The antenna is composed of two back-to-back folded dipoles as a feed for a resonator antenna and reflective walls. The single-resonant metallic EBG as a superstrate was designed. A highly directive radiation pattern is created due to the angle-dependent attenuation of the resonator antenna coupling to free space. Effect of reflective walls height on the performance of the proposed antenna is also studied.
