Abstract: The present disclosure relates to a phase shifter assembly comprising a phase shift circuit and a dielectric assembly having at least one dielectric element movable relative to the phase shift circuit for phase shifting, wherein the at least one dielectric element is disposed at a set distance from the phase shift circuit to form a gap between the at least one dielectric element and the phase shift circuit. In addition, the present disclosure also relates to a cavity phase shifter and a base station antenna.

Abstract: A connection assembly for an antenna includes a printed circuit board and a coaxial cable connected to the printed circuit board. A transmission trace and a solder pad are provided on the printed circuit board. An opening for receiving an end portion of the coaxial cable is also provided in the printed circuit board, and an exposed outer conductor of the end portion extends into the opening, and an exposed inner conductor reaches the solder pad. The connection assembly further includes a ground structure, which is electrically connected to a ground metal layer on a second surface of the printed circuit board, and the ground structure is at least partially arranged on both sides of the exposed inner conductor and/or the exposed outer conductor.
