The Design of Dual-Polarization Slotted Waveguide Phased Array Antenna

This article introduces a dual-polarization waveguide slot antenna design. The horizontally polarized waveguide antenna designed in this paper uses narrow-side oblique slits, and two adjacent pairs of slits are reversed to suppress cross-polarization. The vertically polarized waveguide antenna is designed with a wide edge and a longitudinal slit on both sides of the center line. The antenna has dual-polarization common-aperture low sidelobe and wide-angle scanning performance.
