We have analyzed and compared four types of high-impedance surfaces for low profile antennas. The considered high-impedance surface (HIS) structures are: mushroom-like electromagnetic band gap (EBG); uniplanar compact EBG (UC-EBG); Peano curve; Hilbert curve. These structures are designed to behave effectively as a magnetic conductor surface at 2.45 GHz. The various properties, namely, the return loss, radiation pattern, and gain, of a horizontal wire antenna placed in close proximity to the four types of high-impedance surfaces are simulated and compared using a full wave simulation tool.
