Abstract

The high gain circularly polarized antenna has been investigated, using double polarizing metallic EBG and excitation with a 45° oriented curved strip dipole placed on a ground plane. The electromagnetic band gap (EBG) characteristic is partially reflecting surface (PRS) in x and y axis, which is improved on the electric field of the both polarizes. In this paper consisted in improving the antenna design and characteristics. Ultimately, an antenna was studied at 2.5 GHz with the 19.04 dB gain. The axial ratio remains lower than 3 dB at the resonant frequency.
