1. A connection assembly for an antenna, the connection assembly including a printed circuit board and a coaxial cable that has an inner conductor and an outer conductor connected to the printed circuit board, wherein
a transmission trace is provided on a first surface of the printed circuit board, and a solder pad for electrically connecting the transmission trace is provided on the printed circuit board;
an opening extending completely through the printed circuit board, wherein an exposed portion of the outer conductor at least partially extends in the opening, and an exposed portion of the inner conductor is soldered to the solder pad and is electrically connected to the transmission trace;
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, wherein the ground structure is at least partially arranged on both sides of the exposed inner conductor and/or the exposed outer conductor,
wherein the inner conductor passes completely through the opening.
