Abstract (in Japanese) (See Japanese page) 
(in English) Self-Interference suppression is essential for realizing the MIMO Full-Duplex system. The self-interference suppression method at RF circuit in the receiving terminal has been proposed by authors, where the end-fire-arranged Tx/Rx linear arrays combined with the multiple 180 degree-hybrids at Rx side are used. However, when the receiving antenna is connected with the multiple 180 degree-hybrids by the cables, a large number of connectors are required, therefore, the connection structure becomes complicated. Moreover, the undesired radiation of the connection discontinuity, or the positional deviation of the individually configured antennas occurs. In this report, the integration of the transmission linear array and the multiple 180 degree hybrids is proposed to resolve aforementioned problems. Meanwhile, the self-interference suppression effect of MIMO Full-Duplex system using these integrating antenna and 180 ° hybrid will be confirmed in this report.
