Abstract

The invention belongs to the technical field of communications and provides a base station antenna element. The base station antenna element comprises a reflection plate, die-casting elements, coupling radiation sheets, insulation pads and feed sheets, wherein the die-casting elements are installed on the reflection plate, the number of the coupling radiation sheets is even, and the coupling radiation sheets are closely fixed to the die-casting elements. The insulation pads are arranged between the coupling radiation sheets and the die-casting elements, so that the coupling radiation sheets and the die-casting elements keep insulated. The feed sheets are located in through holes of the die-casting elements, one end of each feed sheet is welded to the corresponding die-casting element, and the other end of each feed sheet is welded to a conductor in a cable. In this way, the base station antenna element has a good cross polar ratio and good intermodulation characteristics and is simple in structure and easy to produce.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a base station antenna element. Background technique [0002] With the development of mobile communication technology, the requirements for base station antennas are getting higher and higher. Base station antennas are generally combined into an array form of radiating elements of the same type to obtain high gain. The gain, cross-polarization ratio, front-to-back ratio, and intermodulation performance of the radiating unit will directly affect the gain, cross-polarization ratio, front-to-back ratio, and intermodulation of the entire antenna. At present, the elements of dual-polarized antennas mostly adopt two pairs of orthogonal half-wave oscillator structures, which are composed of radiators and supporting seats. However, most of the existing antenna elements have complex structures, and the performance of cross-polarization ratio and intermodulation characteristics ne...
