Abstract
A metal rear cover for a terminal and a terminal are provided. The metal rear cover includes a base plate provided with at least one micro-seam band, and the micro-seam band includes a plurality of micro-seams. The plurality of micro-seams are arranged equidistantly, a distance between two adjacent micro-seams is larger than a width of the micro-seam, the at least one micro-seam band divides the base plate into at least two radiation parts including a first radiation part and a second radiation part. A conducting switch is coupled between the first radiation part and the second radiation part, and configured to disconnect or connect the first radiation part with the second radiation part, so that transceiving of different preset frequency ranges can be achieved by the metal rear cover, when the conducting switch disconnects or connects the first radiation part with the second radiation part.
