Description

Technical Field

[0001] The utility model belongs to the technical field of antenna detection, in particular to a base station antenna performance detection device. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. In order to maintain the antenna's good signal transmission and signal reception functions, the antenna performance needs to be tested. Most of the existing antenna performance test equipment requires the installation of a signal receiver around the antenna to detect the antenna's signal transmission function. The staff needs to invest a lot of time in the installation work, which occupies a large area and is not flexible enough in operation.

[0003] There are also technical solutions for base station antennas in the prior art. For example, a Chinese patent with announcement number CN216979186U discloses a base station specific antenna performance test device, including a mounting frame, a shielding tube, a receiver, a mounting seat, a box cover, an antenna body, a through hole and a stud. The upper end of the mounting frame is provided with a box cover, and positioning seats are symmetrically provided on the inner walls of both sides of the mounting frame. A shielding tube is placed inside the positioning seat. A through hole is opened on one side surface of the mounting frame, and a mounting seat is inserted inside the through hole. A stud is installed at one end of the mounting seat passing through the through hole, and a screw sleeve is rotatably sleeved on the surface of the stud. One end of the stud is connected to the antenna body, and the antenna body is inserted into the shielding tube. The mounting frame and the inner wall of the box cover are embedded with receivers distributed in a rectangular array with respect to the shielding tube. By placing the antenna body in the shielding tube, the antenna can be quickly and multi-directionally measured. However, the above technical solution still has defects. This technical solution can only detect the signal receiving performance of the antenna, but cannot detect the signal transmitting performance of the antenna. Moreover, it is relatively cumbersome to replace the shielding tube and the embedded layer, so the installation and operation convenience are insufficient.

[0004] In summary, the present invention provides a base station antenna performance detection device to solve the above problems. Utility Model Content
