Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0016] Such as figure 1 As shown, the present invention adds a laser distance measuring device to the radio frequency test equipment. The five red dots in the middle of the four receiving antennas, that is, the center area of ​​the test equipment, are the laser emission sources.

[0017] Such as figure 2 As shown, in the present invention, a layer of plastic wrap is wrapped on the mouth surface of the radiation antenna, and a film coating that can reflect laser light and transmit radio frequency signals is covered in the central area.

[0018] When performing distance measurement, the laser signal emitted by the laser distance measuring device reaches the thin film coating and is reflect...
