Problems solved by technology

[0003] However, in the existing radiating unit, the coaxial cable needs to be welded with the balun and the radiating arm, which has low efficiency and is likely to cause unstable electrical indicators
In addition, due to the relatively high price of coaxial cables, the cost of the radiation unit is also relatively large

Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0034] see Figure 1 to Figure 5 , as a first aspect, the present invention relates to a radiation unit 100, preferably a low-frequency radiation unit with dual-polarized four-dipoles, through which the feeding part 30 for feeding the dipoles 10 is built into the balun 20, so that Together with the outer wall of the balun 20, it forms a structure similar to a coaxial cable, which feeds the dipole 10, which can reduce the use of coaxial cables and reduce costs; in addition, the feeding part 30 can be formed on the balun during the balun f...

Abstract

The invention provides a base station antenna and a radiation unit thereof. The radiation unit comprises a dipole, a balun supporting the dipole, and a feeding pack for feeding the dipole. The balun comprises a pair of balun arms which are oppositely arranged, at least one balun arm being arranged in a hollow mode; the feed part comprises a feed conductor and an insulating medium, wherein the feedconductor is arranged in the hollow balun arm in a penetrating mode and connected with one radiation arm supported by the other balun arm; and the insulating medium is filled between the feed conductor and the inner wall of the balun arm and enables the feed conductor to be fastened in the balun arm. A feed part composed of a feed conductor and an insulating medium is arranged in an inner cavityof a hollow balun arm; and the feeding part and the balun arm form a structure similar to a coaxial cable, so that coaxial cable feeding is not needed, welding is not needed, welding time is saved, unstable factors of electrical performance caused by welding are reduced, and meanwhile, cost can be reduced due to the fact that the coaxial cable is not used.

Description

technical field [0001] The invention relates to the technical field of mobile communication, 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. In the low-frequency radiation unit used in the existing base station antenna, the coaxial cable is often used to feed the dipole (such as a half-wave oscillator), wherein the outer conductor of the coaxial cable is welded to a balun arm of the balun, and the coaxial The inner conductor of the cable is welded to the radiating arm supported by the other balun arm of the balun, thereby completing the coaxial cable to feed the dipole. [0003] However, in the existing radiating unit, the coaxial cable needs to be welded with the balun and the radiating arm, which has low efficiency and i...
