Title:
DUAL-BAND COMMON APERTURE ANTENNA ARRAY BASED ON DUAL-MODE PARALLEL WAVEGUIDE
Document Type and Number:
WIPO Patent Application WO/2022/134393
Kind Code:
A1
Abstract:
Disclosed is a dual-band common aperture antenna array based on a dual-mode parallel waveguide, suitable for use in the technical field of communications. Comprised are: a waveguide–substrate integrated waveguide adapter structure, a multi-stage cascaded power divider, a transverse coupling gap, a longitudinal coupling gap, a matching through-hole, a common aperture dual-mode parallel waveguide, and a common aperture parallel slot array; the overall structure consists of two layers of dielectric substrate; a signal passes through the waveguide–substrate integrated waveguide adapter structure located on the underlying substrate, and is inputted to the multi-stage cascaded power divider; said dual-band common aperture antenna array based on a dual-mode parallel waveguide can implement a low-band fixed-beam slot array antenna, a high-band multi-beam long-slot leaky-wave antenna, or a fixed-beam slot array antenna. The invention has a simple structure, is multi-functional, has a high degree of integration, and is small in volume and light in weight.
