Abstract :
In this paper, a design of high gain microstrip antenna using planar circularly symmetric electromagnetic band gap structures (PCS-EBG) is presented. The EBG rings round the antenna reduce surface waves propagating along the substrate and support the radiation of electromagnetic (EM) energy in plane perpendicular to the antenna. Because of the circularly symmetry the surface waves are supressed in all radial directions to the same degree. To demonstrate this a panel with six antennas - four without EBG rings, one with two EBG rigs and one with three EBG rings - was modeled and simulated in Zeland IE3D.
