Abstract
An antenna, including: a circuit board including a first grounding point, a second grounding point and a feeding point; a metal ring suspended with respect to the circuit board; a grounding arm; and a feeding short-circuit arm; the metal ring, the grounding arm and the feeding short-circuit arm are spaced from each other, and the grounding arm is between the metal ring and the feeding short-circuit arm; the first grounding point is connected with the grounding arm, the second grounding point and the feeding point are both connected with the feeding short-circuit arm; every two of the metal ring, the grounding arm and the feeding short-circuit arm are coupled with each other to form a ring current on the metal ring, so as to achieve circular polarization properties. The structure and arrangement of the antenna are flexible, so as to be adapted to devices with small internal space.
