| Abstract(in English) | Fixed Wireless Access (FWA) systems in the 26 GHz band have been commercialized in Japan for high-speed Internet connections between subscribers and base stations. Compact and low-cost user terminals are realized by adopting alternating-phase fed single-layer waveguide slot arrays. To double the frequency efficiency, we proposed a dual polarization system that utilizes high XPD of slotted waveguide arrays. Authors have developed H-plane cross-junction multiple way power divider for feeding the array from the center of the aperture, which still lies in the same layer as the radiating waveguides. Recently, the blocking due to the feeding waveguide located in the center of the aperture is remedied by E- to H-plane multiple way power divider with its narrow wall parallel to the aperture. If the blocking of this feed waveguide, still in single layer, can be made small enough, it can run freely in the aperture without causing blockage. This paper demonstrates the predicted and measured characteristics of an E- to H-plane cross-junction as well as the multiple way power divider consisting of its cascade for the use in the alternating-phase fed single-layer waveguide array. |
