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.

Abstract: A low frequency band radiating element for a multiple frequency band cellular base station antenna comprises a dipole arm including a radiating portion and a first coupling portion and a dipole leg that includes a leg and a second coupling portion located at one end of the leg. The first coupling portion is removably connected to the second coupling portion. A thin metal sheet with a suitable electrical performance can be selected for the dipole arm, and a thick metal plate can be selected for a dipole leg so as to achieve mechanical strength
