Summary:
The plate-laminated waveguide slot array antenna is a high-efficiency and wide-band antenna in the millimeter-wave band. However, in the conventional corporate-feed circuit, the number of radiating elements is limited to be a power of two by using a cascade of T-junctions. In this paper, we propose the corporate-feed with a cross junction and an asymmetric T-junction for 12×16 elements. The bandwidth for VSWR less than 1.5 is 7.64%. Antenna efficiency of 82.6% is obtained at the design frequency of 61.5 GHz by simulation.
