Abstract
A foldable electronic device includes a first device body, a second device body, an earpiece, an antenna, and a first switch control circuit. The antenna includes a main radiator and a first parasitic radiator. The main radiator is disposed on the first device body, and the first parasitic radiator and the earpiece are disposed on the second device body. When the foldable electronic device is in a folded state, the main radiator is disposed relative to the first parasitic radiator at a first interval and is coupled to the first parasitic radiator through the first interval. The first switch control circuit includes a first switch component and a plurality of different first matching branches disposed in parallel connection. One end of the first switch control circuit is connected to a ground of the second device body, and the other end is connected to the first parasitic radiator.
