Problems solved by technology

When the integrated die-casting aluminum alloy design is adopted, the radiation unit often needs a longer mold opening cycle, and once the mold opening is completed, it is more difficult to change the design of the radiation arm
If the requirements cannot be met, the mold needs to be re-opened, resulting in increased R&D costs and waste of molds

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0032] It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "installed on" another element, it can be directly on the other element or there can also be an intervening element . When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. . When a component is perpendicular or nearly perpendicular to another component, it means that the ideal state of the two is vertical, but due to the influen...

Abstract

The invention discloses a base station antenna and a radiation unit. The radiation unit comprises radiation arms, a balun structure and an insulating medium piece. The balun structure comprises baluns, the baluns are provided with coupling parts, and the coupling parts are used for coupling a radiation signal to the radiation arms. The insulating medium piece is detachably connected with the balunstructure, and the insulating medium piece is provided with mounting parts for mounting the radiation arms. The radiation arms are fixed on the insulating medium piece through the mounting parts, andare coupled to and matched with the corresponding coupling parts. The radiation unit can adapt to change design of the radiation arms, die waste is reduced, and the research and development cost is reduced. The base station antenna adopts the radiation unit, and the radiation arms can be replaced according to requirements, so that the debugging of antenna performance indexes is more flexible. Theradiation arms can be replaced on an old structure, so that the old antenna can meet new requirements.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a base station antenna and a radiation unit. Background technique [0002] With the development of wireless technology and the introduction of new communication spectrum and communication standards, multi-system shared antennas that support more frequency bands and more standards have gradually become the mainstream products required by operators. [0003] Radiating units of traditional base station antennas are often made of integrated die-casting aluminum alloys. When the integrated die-casting aluminum alloy design is adopted, the radiation unit often needs a longer mold opening cycle, and once the mold opening is completed, it is more difficult to change the design of the radiation arm. If the requirements cannot be met, the mold needs to be re-opened, resulting in increased R&D costs and waste of molds. Contents of the invention [0004] Based on this, it is neces...
