Title:
BROADBAND CIRCULARLY POLARIZED ARRAY ANTENNA STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/124698
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications, in particular, to a broadband circularly polarized array antenna structure, comprising a first dielectric plate, a parasitic patch layer, a second dielectric plate, a radiation patch layer, a third dielectric plate, and a ground plate stacked in sequence from top to bottom. The radiation patch layer comprises a first radiation patch, a second radiation patch, a third radiation patch, a fourth radiation patch, a first broadband phase shifter, a second broadband phase shifter, and a third broadband phase shifter. The parasitic patch layer comprises a first parasitic patch, a second parasitic patch, a third parasitic patch, and a fourth parasitic patch. A first dielectric plate, a parasitic patch layer, a second dielectric plate, a radiation patch layer, a third dielectric plate, and a ground plate are stacked in sequence, parasitic patches are provided in the parasitic patch layer, and radiation patches and broadband phase shifters are provided in the radiation patch layer; thus, the bandwidth can be increased and the purity of circular polarization can be improved.
