Patent attributes
The present disclosure provides an electronic device including a metal housing and at least one switch. The metal housing includes a peripheral frame provided with at least one micro seam band, the peripheral frame is partitioned by the at least one micro seam band to form at least one frame body, the micro seam band is formed by at least two micro seams, and a metal strip is provided between two adjacent micro seams. The switch includes a first end and a second end, the first end is electrically coupled to the frame body, and the second end is electrically coupled to the metal strip. The at least one frame body is an independent antenna. The switch includes a plurality of second ends coupled to different metal strips correspondingly, and a variety of low-frequency bandwidths of the antenna is expanded through different closed or open states of the switch.
