And the control circuit board 5 is arranged in the sealed cavity to prevent interference signals generated by the integrated circuit during operation from radiating out, thereby affecting the normal communication function of the antenna module circuit board.

Wherein, the base 1 comprises a bottom plate 15 and a side plate 16 arranged on the bottom plate 15. The bottom plate 15 and the side plates 16 together enclose the accommodation chamber 14. The mounting arm 11 is extended by the side plate 16, so that the fixing of the antenna accommodating box 4 and the base 1 at two sides is more stable.
