Abstract :
In this letter, a circularly polarized (CP) patch antenna with chiral metamaterial (CM) is proposed. The proposed CP patch antenna is composed of a conventional linearly polarized (LP) patch antenna and a CM. When placing the CM in the presence of a conventional LP patch antenna, the antenna polarization can be changed to CP mode. The antenna performances have been investigated numerically and experimentally. A simple method for realizing CP antenna is provided by using CM in the present letter.
