Title:
HIGH-GAIN LOW-PROFILE CIRCULARLY POLARIZED ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/024626
Kind Code:
A1
Abstract:
The present invention relates to the technical field of antennas for communication. Disclosed is a high-gain low-profile circularly polarized antenna. The antenna comprises a circularly polarized patch at the top, a composite dielectric high-impedance surface array in the middle, and a metal backplate at the bottom, wherein the circularly polarized patch comprises a patch dielectric layer; a first fan-shaped patch, a second fan-shaped patch, a third fan-shaped patch and a fourth fan-shaped patch are formed on an upper surface of the patch dielectric layer; four coaxial feeding lines are provided at positions that are close to the center of the patch dielectric layer; the coaxial feeding lines are vertically arranged; and an upper end of each coaxial feeding line is electrically connected to a corresponding fan-shaped patch, and the other end of the coaxial feeding line penetrates the patch dielectric layer to extend to the outside of a lower surface of the patch dielectric layer.
