Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an electronic device. Background technique [0002] With the development of communication technology, many communication devices have multiple antennas, and these antennas can send and receive wireless signals in different frequency bands. In the prior art, due to the multi-antenna design, these antennas need to achieve resonance through impedance matching. However, different frequencies will introduce the inductance and / or capacitance required for their own resonance, and the inductance or capacitance introduced by supporting two or more frequencies for one antenna will also cause other antennas to need to introduce more matching components, resulting in the entire The size of the antenna module is large, which is not suitable for the thinning and thinning of communication equipment, or the flexible design of the structure, and to a certain extent, it will increas...
