Title:
COMPACT BROADBAND CIRCULARLY POLARIZED ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/050847
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communication antennas. Disclosed is a compact broadband circularly polarized antenna. The circularly polarized antenna comprises an antenna body, wherein a cavity is formed in the antenna body, and several ridges and several baffles are formed inside the cavity; and the ridges are used for antenna miniaturization and bandwidth widening, and the baffles are used to form a spatial phase difference. In the present application, the ridges of the circularly polarized antenna are divided into two parts, wherein the ridges located in a baffle mounting rectangular section and a front rectangular mounting section are used for antenna miniaturization and bandwidth widening, and the baffles for forming a phase difference are arranged between the ridges located in the baffle mounting rectangular section. By means of the configurations, the polarized antenna can be miniaturized, can operate in a millimeter wave band, and can achieve circular polarization; in addition, the ridges are provided in the antenna, such that the bandwidth of the antenna is wider.
