Abstract

The invention provides a UWB (ultra wide band) dual-polarized antenna radiation unit and a base station antenna, and the radiation unit comprises a radiator and a feed Balun which supports the radiator and achieves the feeding for the radiator. The radiator comprises two polarization assemblies, wherein the polarization of the two polarization assemblies is mutually orthogonal, and each polarization assembly comprises two symmetric oscillators, and two-conductor lines connected with the two symmetric oscillators. Two oscillator arms of each symmetric oscillator achieve the feed in a parallel manner through the two-conductor lines with a gap therebetween. Two oscillator arms, located at the same side of a symmetry axis, of the symmetric oscillators of the same polarization assembly are connected through conductors, located at the same size, of the two-conductor lines. Through employing the wide-band characteristics of the symmetric oscillators and forming a structure with at least two grids through a plurality of radiation arms, the radiation unit achieves the wide-band expansion, and the two symmetric oscillators are combined in a parallel manner. Through combining with the advantages of a two-element array, the directional diagram in a wide band is stabilized, and the radiation unit has the good radiation characteristics while achieving the wide band. The radiation unit is simple and compact in structure, is easy to assemble, and meets the application demands of the miniaturization of the radiation unit.

Description

technical field [0001] The invention relates to the technical field of mobile communication base station antennas, in particular to an ultra-wideband dual-polarized antenna radiation unit and a base station antenna. Background technique [0002] As an important part of the mobile communication system, the base station antenna's performance plays a decisive role in the mobile communication system. Due to the rapid increase in the number of users, the requirements for the working frequency bandwidth of various mobile communication systems are getting higher and higher, and at the same time, there are certain requirements for the beamwidth of the pattern within the broadband. At present, there are two main forms of base station antennas, one is a microstrip patch, and the other is a half-wave oscillator. Among them, the frequency bandwidth of the patch antenna is too narrow, and the bandwidth is usually increased by increasing the complexity of the antenna, but the bandwidth i...
