Problems solved by technology

Existing base station antennas mostly use die-casting radiating units, which are installed on the reflector with four screws. Four mounting holes need to be opened on the reflector. Too many holes will easily cause intermodulation problems, resulting in unstable antenna performance.

Embodiment Construction

[0027] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention.

[0028] see Figure 1 to Figure 3 As a first aspect, the present invention relates to a radiating element 100 , such as a low frequency radiating element, comprising a dipole 1 , a balun structure supporting the dipole 1 , and a feeding member 4 feeding the dipole 1 .

[0029] There are four dipoles 1 , and the four dipoles 1 are divided into two pairs, corresponding to work in two mutually orthogonal polarization directions.

[0030] The balun structure includes an annular base 3 , ...

Abstract

The invention provides a base station antenna and a radiation unit thereof. The radiation unit comprises a balun structure, a dipole supported on the balun structure, and a feed part extending along the balun structure to feed a dipole, wherein the balun structure comprises a base and a balun arm connected to the base and supporting the dipole, the base is provided with three mounting holes, the mounting holes extend from the bottom end of the base to the top end of the base, and the three mounting holes are arranged on the base in a non-collinear manner. The three mounting holes are only formed in the base of the balun structure and are arranged in a non-collinear mode to form a triangular mounting framework, and therefore the radiation unit is ensured to have high stability when being mounted on the reflecting plate through screws. In the base station antenna adopting the radiation unit, as the fixed points of the radiation unit are reduced, the hole sites needing to be formed in thereflecting plate can be correspondingly reduced, the cross modulation problem caused by burrs in the hole sites is reduced, and the antenna performance is relatively stable.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a base station antenna and a radiation unit thereof. Background technique [0002] With the development of the communication industry, miniaturized, multi-band and multi-standard base station antennas have increasingly become the mainstream antennas used in the communication industry. Existing base station antennas mostly use die-cast radiating units, which are mounted on the reflector with four screws. Four mounting holes need to be opened on the reflector. Too many holes can easily cause intermodulation problems and lead to unstable antenna performance. SUMMARY OF THE INVENTION [0003] The primary object of the present invention is to provide a radiating unit with a simple structure and reducing the problem of antenna cross-modulation. [0004] Another object of the present invention is to provide a base station antenna with better intermodulation ...
