摘要： 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.

摘要： A power divider includes: a dielectric substrate; a transmission line circuit on a first surface of the dielectric substrate, the transmission line circuit including an input trace, a first output trace and a second output trace. The transmission line circuit is configured to split a signal received at the input trace into a first sub-component that is output on the first output trace and a second sub-component that is output on the second output trace; and a reference potential layer, set on a second surface opposite the first surface of the dielectric substrate, where the reference potential layer is provided with a decoupling window that exposes a part of the dielectric substrate to reduce coupling in the transmission line circuit.
