Base station, broadband dual-polarization filtering magneto-electric dipole antenna and radiation unit thereof

Abstract

The invention discloses a base station, a broadband dual-polarization filtering magneto-electric dipole antenna and a radiation unit thereof. A radiation structure comprises two groups of dipoles withmutually orthogonal polarization directions, and each group of dipoles comprises two oppositely arranged radiators; a balun structure comprises four groups of balun assemblies, wherein each balun assembly comprises two balun grounds which are oppositely arranged at an interval, and a feeder line and an open-circuit branch knot which are oppositely arranged at an interval and are electrically connected; one balun ground is electrically connected with one radiator, and the other balun ground is electrically connected with the other adjacent radiato; the feeder line and one balun ground are oppositely arranged at an interval; the open-circuit branch knot and the other balun ground are oppositely arranged at an interval; and the balun grounds are arranged between the feeder lines and the open-circuit branch knots. Mutual coupling between the radiation units is avoided; in this way, the broadband dual-polarization filtering magneto-electric dipole antenna adopting the radiation unit is good in performance; therefore, the base station adopting the broadband dual-polarization filtering magneto-electric dipole antenna is good in overall performance.

Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a base station, a broadband dual-polarization filtering magnetoelectric dipole antenna and a radiation unit thereof. Background technique

[0002] With the rapid development of wireless communication technology, the broadband dual-polarization filter magnetoelectric dipole antenna (hereinafter referred to as the magnetoelectric dipole antenna) has the advantages of wide bandwidth, high directivity, low cross polarization, and low back lobe radiation. It has a good application prospect. In the application process of the traditional magnetoelectric dipole antenna in the multi-band base station array, in order to meet the miniaturization requirements of the base station, the radiating elements of different working frequency bands are usually spaced close together, resulting in strong mutual coupling, so that the magnetoelectric dipole The overall performance of the a...
