Embodiment 1

[0043] Please refer to Figure 1 to Figure 8 , this embodiment provides a dual-polarized radiation unit, including a folded oscillator 10 , a balun structure 20 connected to the folded oscillator 10 , and a feed conductor 30 for coupling and feeding the folded oscillator 10 .

[0044] The folded vibrator 10 includes four conductor rings, and the four conductor rings are arranged along the circumferential direction. Each conductor ring is symmetrically arranged, and the symmetry axes of two adjacent conductor rings are vertically arranged, and the symmetry axes of the two opposite conductor rings overlap to form a cross coordinate axis S1, and each conductor ring has two centers facing the cross coordinate axis S1 The connection end of the cross coordinate axis S1 is provided with a first branch 151 and a second branch 152 extending toward the center of the cross coordinate axis S1 at the ends facing away from the center of the cross coordinate axis S1 and respectively facing t...

Embodiment 2

[0073] Please refer to Figure 9 , this embodiment provides a base station antenna, including a plurality of dual-polarized radiation units 1 , and for the specific structure of the dual-polarized radiation units 1 , refer to Embodiment 1. Since the antenna of this base station adopts all the technical solutions of the first embodiment above, it also has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0074] Please refer again Figure 9 , a plurality of dual-polarized radiation units 1 are arranged in rows and columns. In the illustrated embodiment, there are ten dual-polarized radiation units 1 arranged in two rows and five columns. The reflection plate 60 of each dual-polarized radiation unit 1 is integrally arranged. Under the working bandwidth of 698MHz-960MHz, the width of the base station antenna can be within 420mm. Under the working bandwidth of 790MHz~960MHz, the width can be within 380mm. ...

Abstract

The invention is applicable to the field of radio, and provides a dual-polarized radiating element and a base station antenna, wherein the dual-polarized radiating element comprises a folded dipole, abalun structure and a feed conductor, wherein the folded dipole comprises four conductor rings which are arranged along the circumferential direction, the conductor rings are symmetrically arranged,the axes of symmetry of two adjacent conductor rings are vertically arranged to form a crossed axis of symmetry, and a first branch and a second branch extending towards the cross shaft conductive center are arranged at the end parts of the two adjacent conductor rings respectively; the balun structure is provided with four communicating holes which are communicated up and down, and any one of theconductor rings is provided with two connecting ends which are respectively connected with the hole walls of the two adjacent communicating holes; and the two feed conductors are arranged in a crossing manner, one end of each feed conductor is inserted into one of the communicating holes, and the other end of each feed conductor is connected with the diagonal communicating hole. The dual-polarized radiating element and the base station antenna provided by the invention has small volume and excellent radiation performance.

Description

technical field [0001] The invention belongs to the radio field, and in particular relates to a dual-polarized radiation unit and a base station antenna. Background technique [0002] As the throat of the wireless communication system, the antenna is an important system component for radiating and receiving electromagnetic waves. The quality of the antenna performance plays a decisive role in the overall performance of the mobile communication system. With the continuous upgrading of mobile communication system in terms of capacity and quality, people put forward higher and higher performance index requirements for base station antennas. [0003] In the era of 1G mobile phones in our country, it was simple voice communication; 2G added SMS services; 3G added Internet access, multimedia, and Internet services, forming three major operator giants that coexist in three coding methods; LTE-4G and 4G have greatly improved Network coverage, and effectively improve the system cap...
