Abstract

The invention discloses a coupling test device, and relates to the field of coupling test. The problem that indicator test of all the antennas of a multi-antenna mobile phone cannot be completed at one test station currently is solved. The coupling test device provided by the invention comprises a first flat plate and a second flat plate which are used to place communication equipment. The first flat plate and the second flat plate are connected up and down through at least one support column. At least two coupling test plates are arranged on the upper surface of the second flat plate. Each coupling test plate is placed in a position corresponding to at least one antenna of the communication equipment and used to perform coupling test on at least one antenna of the communication equipment. The at least two coupling test plates are used to perform coupling test on all the antennas of the communication equipment. A three-dimensional antenna is arranged above one end of each coupling test plate, and the three-dimensional antennas are used to reduce the interference of the antennas, not corresponding to the coupling test plates, of the communication equipment.

Description

technical field [0001] The invention relates to the field of coupling testing, in particular to a coupling testing device. Background technique [0002] With the development of communication technology, some mobile phones containing two or more antennas (ie, multi-antenna mobile phones) emerge as the times require to meet the development needs of multiple systems and frequency bands. Among them, in order to ensure the antenna performance of the multi-antenna mobile phone leaving the factory, each multi-antenna mobile phone needs to pass a strict antenna performance test. Antenna performance test (also called antenna coupling test) can only leave the factory after the indicators of all antennas are normal. [0003] In the prior art, the most commonly used antenna coupling test method is: placing a multi-antenna mobile phone on a coupling test board connected to a comprehensive test instrument, then, by turning on the mobile phone and sending mobile phone verification informa...
