Patent attributes
An electronic device is provided and includes a metal housing and at least one switch. The metal housing includes a peripheral frame provided with at least one micro-seam zone, the at least one micro-seam zone divides the peripheral frame into at least one segment of frame body, each micro-seam zone is formed by at least two micro-seams arranged at intervals, and a metal part 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 part. The at least one segment of frame body is an independent; the switch includes a plurality of second ends coupled to the different metal parts within the micro-seam zone, the antenna expands a variety of low-frequency bandwidths through different open-closed states of the switch.
