Analysis of adaptive antenna having electromagnetic band gap metallic structures

An adaptive antenna is proposed; it is composed of a dipole antenna above a ground plane and two electromagnetic band gap (EBG) metallic structures. It has been found that EBG structures are a good way to create adaptive antennas working in the microwave region. A rigorous analysis of this antenna is efficiently performed using the method of moments, leading to the determination of antenna radiation patterns when one or more metallic rows are removed from the EBG structures.
