This paper proposes an improved self polarizing metallic EBG antenna. The latter is designed by using an electromagnetic band gap material generating the circular polarization by itself. The work presented in this paper consisted in improving the antenna design and characteristics. Ultimately, an antenna was studied at 30 GHz (29.5-30 GHz) with a 21 dBi directivity. The axial ratio remains lower than 1 dB on the whole frequency band.
