Abstract (in Japanese) (See Japanese page) 
(in English) A high-performance wide-bandwidth microstrip rat-race hybrid coupler is presented. The proposed coupler has two additional open-stubs for wideband operations. Although the coupler is simple to fabricate as typical rat-race coupler without via-holes and wire, the phase error between two outputs improves significantly over the desired wideband operations. The fabricated coupler shows a phase difference of below 1.7。ニand under 1 dB loss including connectors。ッ loss in the 5 - 6 GHz band.
