Full TextAbstract
A circular polarized dual spiral-loop antenna has been investigated for a low profile design. Performance of this antenna when it is placed at a distance of 0.06λ above a well-designed EBG surface is studied. Also, the antenna performance using PEC ground plane and without any ground plane is presented. It is shown that the total thickness of the antenna structure is reduced 60% when an EBG surface is used as a ground plane. An axial ratio bandwidth of 8% and a return loss bandwidth of 7.8% are achieved with the proposed low profile structure.
