Abstract (in Japanese) (See Japanese page) 
(in English) The Operated mechanism of a high front-to-back-ratio circularly polarized (CP) antenna with T-branch antenna are proposed in this paper. A linear T-branch element antenna can be provided a high F/B ratio when installed on a large ground plane, but when the ground plane is small, the backlobe increases due to radiation from the open end of the antenna. Therefore, the antenna into a spiral shape on only one side is proposed. The leakage of electromagnetic waves behind the antenna can be reduced and obtained a high F/B ratio even with a small ground plane.
