This paper presents an efficient circuital model based on a transmission line technique to design a planar circularly symmetric (PCS) EBG structure that surrounds a patch antenna working at 2.45 GHz. The EBG structure, being printed on the same layer board of the antenna, is easy to fabricate, prevents the propagation of surface waves and increases the bandwidth and the directivity of the patch antenna.
