Design of a partial-corporate-feed circuit of a waveguide reflection-canceling slot low-sidelobe array antenna in the 60GHz band

摘要

A partial-corporate-feed waveguide reflection-canceling 16×28-slot array antenna is designed for 60 GHz band in order to suppress the sidelobe level by excitation of Taylor distribution. The simulation by HFSS gives low sidelobes by redesign of the feed waveguide. The measurement result is improved by eliminating isolated etching pattern of the feeding layer.
