Document Type and Number:
WIPO Patent Application WO/2022/099585
Kind Code:
A1
Abstract:
Disclosed by the present application is a dual-polarized four-ridge waveguide array antenna, comprising: a waveguide radiating cavity array and a multilayer PCB arranged below the waveguide radiating cavity array; the waveguide radiating cavity array comprises m × n open four-ridged waveguide units, each open four-ridge waveguide unit being an open waveguide cavity provided with a ridge-shaped part in the middle of each of the four side walls, m and n being natural numbers greater than or equal to 1; the upper and lower surface layers of the multilayer PCB are grounding layers, two layers of the multilayer PCB spaced apart from each other are polarized orthogonal feed network layers, respectively, a grounding layer is provided between the two layers spaced apart from each other, and each feed network layer comprises m × n feeder cells corresponding to the m × n open four-ridge waveguide units of the waveguide radiating cavity array; each feed network layer has one feed port.
