Title:
DUAL-POLARIZED WAVEGUIDE ARRAY ANTENNA SHARED BY TRANSMITTING AND RECEIVING
Document Type and Number:
WIPO Patent Application WO/2018/058722
Kind Code:
A1
Abstract:
The present invention relates to the field of communication and measurement and control, in particular to a dual-polarized waveguide array antenna shared by transmitting and receiving, comprising N broadband dual-polarized antenna sub-arrays and a polarization adjustment apparatus. Each of the broadband dual-polarized antenna sub-arrays comprises a dual-polarized open-ended waveguide array radiation layer and a network feed layer. The dual-polarized open-ended waveguide array radiation layer is provided above the network feed layer. The polarization adjustment apparatus is provided below the network feed layer. The present invention uses a waveguide network structure to feed a plate satellite antenna, expanding an operation bandwidth of the plate satellite antenna, realizing sharing an antenna aperture by transmitting and receiving, reducing a radiation grating lobe, and providing an interface for the automatic adjustment in the electromagnetic wave polarization direction.
