Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a novel array antenna for DOA estimation system is proposed. The proposed array antenna consists of four patch elements, a both-sided feed circuit including a magic-T with offset excitation. In the DOA estimation system, the arrival angle is obtained by the ratio of summational and differential signals between two patch elements. By using the magic-T in the feed circuit, the summational and differential signals can be obtained easily with simple structure. In this paper, the characteristics of the proposed array antenna are experimentally investigated, and the estimation angle range of -24° to +15°was obtained.
