Abstract
The present disclosure provides an electronic device including a metal housing and a plurality of antennas operating at different frequency bands. A frame of the metal housing is provided with at least one gap, each frame segment of frame segments on both sides of each gap is configured as a radiation structure shared by at least one antenna. Each antenna includes a signal circuit and a matching circuit, the matching circuit is coupled in series between the signal circuit of the antenna where the matching circuit is located and the radiation structure, and configured to output a signal matching with an operating frequency band of the antenna where the matching circuit is located and filter out signals that are coupled from other antennas of the gap and match with operating frequency bands of other antennas of the gap.
