Abstract

The present application discloses a broadband circularly polarized magnetoelectric dipole antenna. By setting a metal parasitic ring, the circularly polarized bandwidth of the antenna can be greatly improved without changing the main structure of the antenna. At the same time, the broadband circularly polarized magnetoelectric dipole antenna of the present application adopts the feeding method of slot coupling, and adopts the metal feeding strip on the lower surface of the dielectric substrate to couple the coupled signal to the horizontal metal patch above the metal floor through the rectangular slot and vertical metal patch, and set a metal parasitic ring around the metal patch module to introduce a new circularly polarized resonant mode for the magnetoelectric dipole antenna, so that the antenna has a better circular polarization in the broadband operating bandwidth. Polarization characteristics. In addition, the structure of the metal parasitic ring will not affect the structure of the antenna, and, on the premise of maintaining the broadband circular polarization bandwidth, the gain fluctuation in the working frequency band is small, and the gain bandwidth of the broadband and better flat gain.

Description

technical field [0001] The present application relates to the technical field of microwave radio frequency, and in particular, to a broadband circularly polarized magnetoelectric dipole antenna. Background technique [0002] With the rapid development of wireless communication technology, the requirements for broadband antennas are getting higher and higher. Magnetoelectric dipole antennas, with their wide bandwidth, low back radiation, and stable radiation pattern, have gained extensive attention in recent years. At present, magnetoelectric dipole antennas have been widely used in 5G communication systems, base station communication systems and wireless local area networks. [0003] Traditional magnetoelectric dipole antennas mainly radiate linearly polarized waves and cannot radiate circularly polarized waves, but circularly polarized antennas can receive incoming waves from any direction, and can avoid the polarization mismatch problem caused by multipath interference. ...
