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.

Abstract: The present disclosure discloses a mounting structure, an antenna device and a method for assembling the antenna device. The mounting structure is used for mounting a connector to a first fixing part and a second fixing part, and comprises: a main body portion which defines a hollow cavity for receiving the connector, a first flange arranged on an upper surface of the main body portion around the hollow cavity and a second flange arranged on the upper surface of the main body portion around the first flange and spaced apart from the first flange; a protective pad received in a protective pad receiving portion defined between the first flange and the second flange; a supporting component to be fixed to the second fixing part, the main body portion being fitted within the supporting component; and at least one fastener used for fastening the mounting structure to the first fixing part, so that the first flange comes into direct contact with the lower surface of the first fixing part.
