Abstract (in Japanese) (See Japanese page) 
(in English) When adjacent rectangular waveguides are alternating-phase fed, the field distribution is maintained even though the structure becomes a parallel-plate waveguide by removing the shared side walls. If the slots are offset from each other at intervals of a half guided wavelength, undesired second-order lobes are radiated, so we propose a structure in which no offset slots are excited by metal posts. A crossed-slot layer is added for circularly-polarization. We introduce a structure in which the equivalent circuit for the element is represented only by a parallel conductance both for the feeding and radiating parts. The input conductance of an array excited by a standing wave is expressed as the sum of the parallel conductances of the elements, which simplifies the design. As a result of the design, the axial ratio is 0.3 dB, the realized gain is 19.7 dBic, and the antenna efficiency is 94.1 % in the 4x4-slot array at the design frequency of 5.8 GHz.
