According to the scheme, the radian curved surface is arranged at the end part of each antenna ridge, so that the typical value of the standing wave coefficient is smaller than 2, the test accuracy is improved, and meanwhile, the 20G-44 GHz signal test can be covered. Through the design that the splicing assembly is arranged on the shielding panel, the splicing assembly penetrates into one end of the shielding panel to receive signals in the shielding box. Through independent but the shield panel convenient and fast installs on the shielded cell wall, has improved the installation effectiveness greatly. And the two groups of coaxial connectors are respectively connected with the two pairs of antenna ridges to receive signals and connected with an upper computer to feed back signals.

One preferred scheme is, be provided with two signal needles on the concatenation casing, two the signal needle is the cross distribution, two the signal needle passes two pairs respectively the antenna spine is with two sets of coaxial connector connects.

According to the scheme, the signal pin is conveniently and finely adjusted by adopting the design of the signal pin which is separately installed from the coaxial connector, so that the test precision is conveniently calibrated.

According to a preferred scheme, the splicing shell comprises two connecting plates, two cover plates and a tail end plate, the two cover plates are connected through the two connecting plates, the four antenna ridges are respectively and integrally arranged on the two connecting plates and the two cover plates, and one ends, far away from the radian curved surface, of the two connecting plates and the two cover plates are fixedly connected with the tail end plate.

According to the scheme, the two connecting plates and the two cover plates are spliced in a segmented mode, so that the processing difficulty of a single part is reduced, the detection structure is convenient to detect whether the structure meets the requirement, and the manufacturing cost is greatly saved.

One preferred scheme is, be provided with on the shielding panel with the spacing hole of concatenation subassembly looks adaptation, be provided with on the concatenation casing with spacing complex connection boss in spacing hole, connect the boss pass through the bolt with the shielding panel is connected fixedly, connect the boss with be provided with the shielding gasket between the shielding panel.

According to the scheme, the connecting boss is arranged on the splicing shell, so that the splicing shell and the shielding panel provide a connecting station, and the shielding gasket is arranged to prevent external interference signals from passing through the limiting hole into the shielding box.

Preferably, both sides of one end of the antenna ridge, which is far away from the radian curved surface, are in a chamfer shape.

According to the scheme, the mutual interference caused by the contact of the adjacent antenna ridges is avoided by arranging the chamfer structure.
