Problems solved by technology

However, due to the large difference between the test conditions and the actual application scene during the POGO Pin non-welding detection process, the test result has a large error, and the accuracy rate is only about 50%, which is easy to cause misjudgment of the quality of the antenna vibrator, and can only be used for qualitative analyze

Abstract

The invention provides an antenna oscillator electrical performance test device and test method. The device comprises a reflecting plate, a PCB (Printed Circuit Board), a welding seat and a conductive material, the reflecting plate, the PCB and the welding seat are assembled in sequence; a cavity is formed in the welding seat, and the conductive material is arranged in the cavity; a first through hole is formed in the reflecting plate, and a second through hole is formed in the PCB; a metal feed needle in the antenna to be tested can penetrate through the first through hole and the second through hole and then make contact with the conductive material, and then the conductive material makes contact with the bottom of the welding base. The testing device can test the electrical performance of the antenna oscillator under the condition that the antenna to be tested is not welded with the device and is close to an actual application scene, the testing accuracy can reach 100%, and the testing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of antenna testing, and in particular relates to a test device and a test method for the electrical performance of an antenna vibrator. Background technique [0002] Massive antenna technology, also known as Msaaive MIMO, is a key technology for 5G mobile communications. As the name implies, hundreds of antennas (128, 256 or more) are installed at the base station, so that hundreds of antennas can send and receive data. [0003] These antennas generally use the PCB for RF feed in the AAU machine, and the connection between the antenna and the feed PCB is generally soldered. The antenna needs to be inspected for radio frequency electrical performance before being assembled into the AAU machine. The existing technology is to use a special fixture-customized POGO Pin to carry out non-welding inspection. However, due to the large difference between the test conditions and the actual application scene during t...
