Abstract :
We propose a low-profile high-gain electromagnetic band-gap (EBG) resonator antenna that utilizes a double-sliced frequency-selective surface (FSS) on a single superstate. In this design, a microgenetic algorithm is employed to optimise the FSS so that the EBG resonator antenna can achieve a directivity of 22 dBi, which is normally achieved by EBG antennas with multiple dielectric layers.
