Abstract: A multi-layer phase shift driving device for an electrically regulated antenna includes multiple control boards that are spaced apart from each other, each of which is arranged with respective phase shift driving mechanisms for driving brushes of the electrically regulated antenna, and arranged with a plurality of holes through which rods pass, wherein each control board is provided with at least one of said rods fixed thereto to serve as fixing rods of the control board and serve as guiding rods of the other control boards of the multiple control boards, such that the multiple control boards can be driven independently of each other.

Abstract: The present disclosure relates to an antenna housing, comprising: a front housing having a front housing edge; and a back housing having a back housing edge, the front housing edge and the back housing edge engaging each other to assemble the front housing and the back housing together to form the antenna housing. The front housing edge and the back housing edge cooperate with each other to form a sealing interface, including: a first sealing member provided with a first sealing portion; and a second sealing member provided with a second sealing portion, the first sealing portion abutting against the second sealing portion when the front housing and the back housing are assembled so that a clearance fit is formed between the front housing edge and the back housing edge, wherein the second sealing member is further provided with a channel positioned inside the second sealing portion and extending parallel to the second sealing portion.

Abstract: A linkage device of a linkage mechanism for a base station antenna is integrally formed with: a body; a flange extending outwardly from the body; a mounting portion suspended from the body and configured to mount the linkage device into the base station antenna, and a coupling portion disposed on the body and configured to couple the linkage device to a drive mechanism of the base station antenna, wherein the flange is formed with a guide configured to cause operation of a phase shifter of the base station antenna.
