Problems solved by technology

[0003] However, some current antenna test devices can only detect some conventional antennas, such as FPC and LDS antennas through the detection of golden fingers on the surface, and Stamping antennas to detect spring pins. They cannot be used for antennas with surface-mounted RF connectors, and additional A special radio frequency test converter is used for testing; furthermore, in the prior art, during the test process for antennas mounted with radio frequency connectors, the miniature radio frequency test converters and radio frequency connectors used to test the test equipment of radio frequency connectors The contact method is hard contact, and there will be poor contact within the range of the upper and lower deviations of the tested antenna height, and there is a certain percentage of the probability of crushing the RF connector of the tested antenna

Abstract

The invention provides an antenna testing device, which comprises a driving assembly and a detection assembly, wherein the detection assembly is installed on the driving assembly; the detection assembly comprises an RF converter, an upper die, a lower die man body and a low die base; the upper die and the lower die main body are oppositely arranged; the RF converter is connected with the upper die, an antenna fixing groove is formed in the lower die main body on the surface opposite to the upper die, and the lower die main body is arranged on the lower die base through an elastic member; and the lower die base is fixed to the driving assembly, and the driving assembly is used for driving the lower die base so that the lower die main body is in contact with the upper die. The antenna testing device can be used for detecting performance of an antenna adhered with an RF coupler, can avoid test error or damage to the RF coupler of the detected antenna caused by size deviation or rigid contact between the RF coupler of the detected antenna and an RF coupler of the detection assembly during the detection process, and is conducive to contact.

Description

technical field [0001] The invention relates to the testing field, in particular to an antenna testing device. Background technique [0002] Before the antenna is finished and put into use, it needs to go through the antenna testing device to conduct simulation tests on its various performances. Only after passing the test can it be listed as a qualified antenna. With the explosive growth of consumer electronics, especially large-screen mobile phones, the distance between the antenna and the modules on the motherboard is getting farther and farther; at the same time, the traditional wires used for signal transmission on the motherboard are gradually changed to use the signal loss rate The smallest high-frequency terminal coaxial cable is used as a dedicated signal transmission tool, and this change requires the antenna to use a surface-mounted RF connector to match the Cable high-frequency terminal interface. [0003] However, some current antenna test devices can only dete...
