Abstract	A 22×20-element double-layer waveguide slot array antenna is designed for a fixed wireless access system in the 40 GHz band. To minimize the interference from surrounding buildings, the Taylor distributions are adopted in both longitudinal and transverse directions of antenna aperture to suppress the sidelobe levels below −30 dB. A four-corner feed structure instead of the typical center feed one is introduced for wideband operation. The perfect magnetic conductor terminations are also adopted at the center of feeding waveguides due to the symmetric feed from right-and-left ends. As the predicted antenna performance by using HFSS, the antenna gain of more than 31.8 dBi and the reflection of less than −12 dB are estimated over the operating frequency range of 39.0 ∼ 41.5 GHz.
