Abstract

The invention provides a planar omnidirectional circularly polarized antenna, and belongs to the field of antenna equipment. The antenna comprises a substrate, a front metal layer arranged on the front side of the substrate, a plurality of front metal radiation structures arranged on the outer periphery of the front metal layer and around the center of the substrate, a rear metal layer arranged onthe rear side of the substrate, a plurality of rear metal radiation structures arranged on the outer periphery of the rear metal layer and around the center of the substrate, a metallization feed hole formed in the center of the substrate, a plurality of metallization shielding through hole groups and a radio frequency chip structure, wherein the metallization shielding through hole groups are distributed around the metallization feed hole and penetrate the front metal layer and the rear metal layer, and the radio frequency chip structure is arranged on the front side of the front metal layerand connected with the metallization feed hole through a first bonding wire. The planar omnidirectional circularly polarized antenna has large beam width and wide coverage, and communication schemesof any angle and any placement mode can be realized; the number of antennae in the system can be effectively reduced, the debugging difficulty of the system is reduced, the operation efficiency of thesystem is improved, and integration of the antennae and the system can be achieved conveniently.

Description

technical field [0001] The invention belongs to the technical field of antenna equipment, and more specifically relates to a planar omnidirectional circularly polarized antenna. Background technique [0002] Antenna technology is an indispensable and important part of wireless communication and detection technology. Antennas provide information exchange channels for wireless radio frequency communication. Traditional antennas are mainly designed with linear polarization, and linear polarization is divided into horizontal polarization and vertical polarization. During the use of the antenna, the receiving antenna and the transmitting antenna must be in the same linear polarization to work properly. , therefore, the antenna is extremely sensitive to the installation method, which is not conducive to the application in complex and changeable environments, and the beam width of the traditional antenna is not very wide, which limits the communication angle range of a single anten...
