In this paper, a wideband dual rectangular loop antenna over an EBG surface is proposed for low profile wireless applications. A low frequency mushroom-like EBG surface is used as the antenna ground plane. In comparison with a PEC ground plane, design of antenna above an EBG ground plane results in 60% reduction of the structure thickness. The investigated antenna is designed for circular polarization. It is shown that the axial ratio bandwidth (<3dB) and return loss bandwidth (<10dB) of the dual rectangular loop antenna above the designed EBG surface are 18% and 14%, respectively. The simulated and measured results are in good agreement.
