Pixel and patch comparison circular polarization: For ARMA new agile circularly polarized approach

This paper presents the new approach for building agile antenna beam forming ARMA. The concept of this antenna is based on the pixel derived from electromagnetic band-gap material antenna. ARMA was published in many papers concerning the linearly polarized agile matrix antennas that show the performances and the interest of this new approach in comparison with the classical agile antennas. In this paper we study the pixel generating circularly polarized field and a comparison with the patch antenna.
