Abstract

This application provides a foldable electronic device and an antenna system for same. The antenna system includes a main antenna element and a parasitic antenna element. The main antenna element is an antenna structure having a radiation characteristic of a current loop antenna, and includes a feed point and a first radiating branch disposed on a first body of the electronic device. The parasitic antenna element includes a second radiating branch disposed on a second body of the electronic device. In a folded state, the first radiating branch and the second radiating branch are at least partially overlapped. The first radiating branch is configured to perform magnetic field coupling with the second radiating branch, to form current loop radiation on both the first radiating branch and the second radiating branch, and a current direction in a current loop formed on the first radiating branch is the same as a current direction in a current loop formed on the second radiating branch. In this manner, longitudinal currents in a same direction may be simultaneously excited on a foldable grounding plate of the electronic device, to achieve a purpose of reducing or eliminating energy consumed in the folded state and increasing antenna efficiency, effectively resolving a problem of poor antenna efficiency in a low band of the electronic device in the folded state.
