Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed an optimization design method for excitation coefficients that maximizes multiplexing transmission channel capacity at a given propagation distance in rectangular-coordinate orthogonal multiplexing transmission system. In this paper, we design a 16x16-element monopulse waveguide slot array antenna with corporate-feed that realizes the optimized excitation coefficients. We design a corporate-feed circuit that excites radiating elements with desired amplitude and phase distribution, and analyze the 16 × 16-element monopulse array combining the radiating elements, the corporate-feed circuit, and a two-dimensional monopulse circuit. 15.7 % bandwidth of VSWR less than 2.0, 37.3 dB or more between 2 input ports are achieved. Excitation amplitude error is 0.3 dB and phase error is 4.7 degree at the design frequency.
