Abstract (en)
[origin: EP3764469A1] Embodiments of this application disclose an antenna. The antenna is disposed on an insulation medium of a circuit board, and the antenna includes a loop radiator, a signal feed-in part, a first conductive ground structure, and a second conductive ground structure. A first end of the loop radiator is connected to the first conductive ground structure, a second end of the loop radiator is connected to the signal feed-in part, and the loop radiator independently generates a first radiation signal based on a function of a current. The loop radiator and the second conductive ground structure form a groove, the loop radiator and the second conductive ground structure jointly generate a second radiation signal in an opening direction of the groove based on a function of a current, and a radiation direction of the first radiation signal is different from a radiation direction of the second radiation signal. All of the signal feed-in part, the first conductive ground structure, and the second conductive ground structure are connected to a radio frequency circuit of the circuit board. The antenna provided in the embodiments of this application can send signals in two directions, so that the antenna has a wider radiation range.
