Abstract: A communications terminal includes a mainboard, a conductor bezel, a first conductor part, and a second conductor part, where a first location on the conductor bezel is electrically connected to a ground terminal on the mainboard, a second location on the conductor bezel is electrically connected to a ground terminal on the mainboard, the second conductor part is electrically connected to a fourth location on the conductor bezel, and a radio frequency port on the mainboard is electrically connected to a third location on the conductor bezel using the first conductor part; and the fourth location and the third location on the conductor bezel are between the first location and the second location. The communications terminal is conducive to reducing antenna assembly complexity and reducing manufacturing costs.

Abstract: A Bluetooth earphone includes an antenna and a circuit board. The circuit board includes a first grounding branch and a second grounding branch. The first grounding branch is connected in series to a first switch, and the second grounding branch is connected in series to a second switch. When the first switch is on, the first grounding branch serves as a current return path of the antenna. When the second switch is on, the second grounding branch serves as a current return path of the antenna. By controlling the on or off state of the first switch and the second switch, the Bluetooth earphone can switch ground structures of the antenna and select different current return paths for the antenna, to switch radiation patterns of the antenna.
