Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method to decrease back-lobe radiation of the small CP antenna. The proposed CP antenna is composed of four antenna elements arranged 90 degrees rotational symmetry on the ground, which are excited with the same amplitude and 90 degrees phase difference. Each antenna element is formed by a spiral antenna branched from the near the middle of an inverted L antenna. From the result of simulation, backward radiation of the proposed CP antenna can be decreased up to 13dB by adding the spiral elements.
