[0002] At present, the method of RF performance coupling test (2G / 3G / 4G / WIFI / BT / GPS) of wireless communication products (mobile communication terminals) such as mobile phones is to place the product under test directly on the test antenna or close to the test antenna. Generally, the test does not take into account the sufficient coupling between the antenna radiation area of the product under test and the test antenna radiation area, and the influence of the material of the test fixture on the wireless signal is not taken into account. Such a test method causes a broken machine with low power. , but the test result is normal, and the purpose of effectively intercepting bad and bad machines cannot be achieved, and the test reliability is not good.

Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0025] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should ...

The invention is applicable to the technical field of radio-frequency performance test of mobile communication terminals, and discloses a darkroom-like coupling test method and test equipment for radio-frequency performance test. The darkroom-like coupling test method comprises the following steps: fixing wireless communication equipment by a clamp; making the radiation direction of an antenna ofthe wireless communication equipment opposite to the radiation direction of a test antenna; and adjusting the positions of the wireless communication equipment and the test antenna, so that the coupled radiation power of the wireless communication equipment reaches the maximum value, and a bad machine is used for checking and then test is carried out. The darkroom-like coupling test equipment comprises a shielding box, the clamp arranged inside the shielding box and used for clamping the wireless communication equipment, the test antenna arranged in the shielding box and arranged with the clamp oppositely at intervals, and a coupled radiation power detection device used for monitoring the coupled radiation power of the test antenna and the wireless communication equipment. The darkroom-like coupling test method and test equipment for the radio-frequency performance test provided by the invention can effectively intercept the bad machine, and the test reliability is good.
