Problems solved by technology

[0003] The existing vibrator structure is not very stable, it is inconvenient to install, and additional plastic parts are required to fix the vibrator arm, which will cause a lot of troubles, such as troublesome installation and difficult debugging. In addition, due to the unstable structure, the antenna of the whole machine will pass through at one time The rate is not high, and the production cost increases

Embodiment Construction

[0019] The specific implementation of the present invention will be further described below in conjunction with the examples.

[0020] Such as Figure 1-4 As shown, a dual-polarized ultra-wideband base station antenna radiation unit includes a dipole balun 101, four dipole arms 102, and two cables 103. The dipole balun 101 is a symmetrical hollow structure, and the dipole arm 102 and dipole balun 101 Formed in one piece, this integrated design enhances the stability and consistency of the dual-polarized ultra-broadband radiating unit, and the four dipole arms 102 that make up the radiator form a center-symmetrical and orthogonal combination around the dipole balun A polarization distribution of plus or minus 45 degrees is formed. The four vibrator arms 102 are located on the same plane and the height between them and the metal reflector 104 is a quarter wavelength; the vibrator arms 102 are rectangular and have hollow polygons inside. There are rectangular hollow gaps between...

Abstract

The invention discloses a dual-polarized broadband base station antenna radiating unit. The unit includes an oscillator BALUN, four oscillator arms and two cables; the oscillator balun is of a symmetric and hollow structure, the oscillator arms and the oscillator balun are integrally formed, the four oscillator arms forming a radiating body are symmetrical by using the oscillator balun as the center and are orthogonally combined to form a plus or minus 45-degree polarized distribution, the four oscillator arms are located on the same plane, and the distance between the plane where the four oscillator arms are located and metal reflection plates is the one-fourth wave length; the oscillator arms are rectangular and are internally provided with hollow polygons, and a rectangular hollow gap is formed between every two adjacent oscillator arms. The dual-polarized broadband base station antenna radiating unit is high in installation stability, good in batch production consistency, good in cross polarization ratio and high in port isolation degree, has 698-960MHz broadband characteristics, meets the requirement of an existing broadband base station antenna, has higher bandwidth, provides conditions for future expansion, and has broad application prospects.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-polarization broadband base station antenna radiation unit. Background technique [0002] The base station antenna is an energy conversion device in the mobile communication system. The electromagnetic wave signal emitted by the mobile station is converted into an electrical signal through the base station antenna for processing by the base station: reversely, the base station converts the electrical signal into an electromagnetic wave signal through the base station antenna in free space The mobile station can receive the electromagnetic wave signal randomly, so as to realize the two-way communication of the mobile communication system. Mobile communication has entered people's life and plays an important role. With the development of a new generation of technology, the demand for multi-system sharing of antennas is getting higher and higher, which poses higher challenges and requirements f...
