Description
Technical Field
One or more embodiments of the present disclosure relate to the field of performance testing technologies for electronic and steam products, and in particular, to an antenna radio frequency testing tool and an antenna testing method.
Background
Antennas are important components for transmitting and receiving electromagnetic energy in wireless communication systems. Since the antenna cannot be integrated into a chip in a semiconductor process in the prior art, the radiation body of the antenna is another critical component that affects the transmission characteristics of the antenna module in addition to the core system chip in the antenna module.
In the prior art, the FPC flexible printed circuit is widely applied to various communication fields due to low price and mature technology; the 5G communication era comes, and wireless communication equipment with a metal frame is very popular in the market with beautiful appearance, good structural strength and metal tactile experience. The two antenna technologies are mature, but the reject ratio after production and assembly is still high, so from the production point of view, the performance test is very important in the production and assembly process.
At present, the antenna testing method which is most widely applied in the production field is to perform a feed test by contacting a probe with a testing pad of an antenna, and the testing mode needs the testing pad to be perpendicular to the probe. The structure of the existing wireless communication equipment is more and more complex, and when a test pad of an antenna is designed to be positioned at the corner position of the side wall or two walls of a frame due to the structural limitation, a probe contact type test is not suitable because the probe contact type test is difficult to directly contact with the test pad.
Currently, two types of test tools are commonly used: cylinder side spring type and spring side spring type.

Most antenna factories use the method, but the structure is relatively complex, the manufacturing cost is high, the multiple switching precision is not very high, the air cylinder can interfere the performance test of the antenna to a certain extent, the strict calibration is needed before the use, and the complex structure causes the maintenance to be complex.

In order to ensure the reliability and yield of products, it is necessary to provide an antenna radio frequency performance testing tool which simultaneously meets a top spring test (that is, a product is horizontally placed and a testing pad is in a horizontal state) and a side spring test (that is, a product is horizontally placed and a testing pad is in a vertical state).
