DUAL-POLARIZED WAVEGUIDE SLOTTED ARRAY ANTENNA

摘要

A dual-polarized waveguide slotted array antenna is disclosed. The dual-polarized waveguide slotted array antenna comprises: a T-junctioned feed waveguide; a folded waveguide connected to the T-junctioned feed waveguide by six coupling slots and provided on the T-junctioned feed waveguide; and a radiating ridged waveguide connected to the folded waveguide by a C-shaped coupling slot and provided on the folded waveguide. The folded waveguide and the radiating ridged waveguide are configured in an m x n array form, and are provided in n numbers, respectively, per one T-junctioned feed waveguide. The radiating ridged waveguide provided on the same T-junctioned feed waveguide has an output slot formed in a first direction slanted with respect to a length direction of the T-junctioned feed waveguide. The radiating ridged waveguide provided on a T-junctioned feed waveguide adjacent to a certain T-junctioned feed waveguide has an output slot formed in a second direction slanted with respect to the length direction of the T-junctioned feed waveguide. The first and second directions form an internal angle of 90 degrees therebetween.
