Abstract :
In this paper, multi-conductor transmission-line (MTL) theory is applied to modeling and analysis of shielded two-layer mushroom-type electromagnetic bandgap (EBG) structures. The slow-wave mode predicted by this method is used to design a compact patch antenna. To further reduce the size of the patch antenna, it is shorted at its center resulting in one of the most compact patch antenna design reported in literature with a dimension of 0.1λ0 by 0.18λ0 with a maximum gain of 2.9dB.
