Problems solved by technology
[0009] 1. The appearance of the product is not very similar to the real exhaust pipe, and the concealment effect is limited;
[0010] 2. The radome and the base are fixed by glue, the structural strength is unstable, and it is easily affected by various factors such as climate, material quality and craftsmanship;
[0011] 3. The lower part of the antenna is not completely closed, so it cannot be reliably waterproof, dustproof and pest-proof;
[0012] 4. The lower cover of the antenna cannot be locked reliably. Non-professionals can easily open the lower cover without any tools, and the antenna loses its basic anti-theft and anti-sabotage capabilities. For this antenna, it is mainly used in semi-open environments such as urban roofs. This point is particularly important;
[0013] 5. The RF connector of the antenna and the RCU cable connector are freely coiled in the antenna body. During the assembly process of the antenna or under the action of external force, it is easy to cause fatal damage to the internal feeder network of the antenna.

Embodiment Construction
[0064] Below in conjunction with accompanying drawing and embodiment describe in detail:
[0065] 1. Overall
[0066] Such as Figure 1.1 , 1.2 , 1.3, the present invention includes working objects: inclination phase shifter 60, downtilt transmission system 70, radio frequency connector 80 and AISG plug 90;
[0067] It is characterized by:
[0068] A top cover 10, a radome 20, an antenna body 30, a bottom mounting frame 40 and a lower housing 50 are provided;
[0069] Its connection relationship is:
[0070] The top cover 10, the radome 20 and the bottom mounting frame 40 are sequentially connected to form a cavity;
[0071] The antenna body 30 is installed in the cavity, and is fixed from both ends by the radome 20 and the bottom mounting frame 40;
[0072] The lower shell 50 is wrapped around the lower part of the radome 20 and the outer side of the bottom mounting frame 40 to protect the internal structure, fix the RF connector 80 and the AISG plug 90, and realize the fu...

The invention discloses a high-performance mechanical structure of an exhaust-pipe electric tilt antenna, relating to the technical field of electric tilt antennas. The structure is characterized in that a top cap, an antenna housing and a bottom mounting bracket are sequentially connected to form a cavity body, and an antenna body is installed in the cavity body and are fixed from two ends through the antenna housing and the bottom mounting bracket; a lower shell body is packed at the lower part of the antenna housing and the outer side of the bottom mounting bracket to protect an inner structure and fix a radio-frequency connector and an AISG (Antenna Interface Standards Group) plug, realizing the fully enclosed antenna appearance; an electrical downtilt phase shifter receives an RCU (Remote Control Unit) through an electrical downtilt transmission system to control an electrical downtilt of the antenna; and the electrical downtilt transmission system receives the control of the RCU to change the sliding block position of the electrical downtilt phase shifter. Under the conditions of smaller antenna appearance size and weight, various function requirements of the exhaust-pipe electric tilt antenna can be realized, the working reliability of the exhaust-pipe electric tilt antenna is increased, the operation of the antenna is simpler, and the antenna installation and debugging difficulty is also reduced.
Description
technical field [0001] The present invention relates to the technical field of electronically adjustable antennas, in particular to a mechanical structure of a high-performance exhaust pipe electronically adjustable antenna, in particular to an exhaust pipe with a built-in RCU (Remote Control Unit, remote control unit) with vertical downtilt adjustment. The tube-shaped integrated beautifies the mechanical structure of the antenna. Background technique [0002] With the continuous improvement of people's quality of life, mobile communication operators not only need to provide high-quality network communication services, but also the erection of antennas must meet the requirements of a concealed appearance that blends with the shape of the building or the environment. The erection of base station antennas in the traditional way will become more and more difficult, because it is difficult to eliminate the concerns of some people about electromagnetic radiation, and it does not ...
