    Abstract: A switch in an electronic device includes a substrate, a first signal line, a second signal line, and a ground bridge. The first signal line is on the substrate and extends in a first direction. The second signal line is on the substrate and is spaced apart from the first signal line in a first direction parallel with the first signal line to branch the wireless communication signal at a first point and a second point of the first signal line. The ground bridge is at least partially movable in a space between the first signal line and the second signal line. A first capacitor is between a first point of the first signal line and one end of the second signal line, and a second capacitor is between a second point of the first signal line and the other end of the second signal line.
