Title:
FOLDABLE ELECTRONIC DEVICE AND ANTENNA SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/116006
Kind Code:
A1
Abstract:
Provided in the present application are a foldable electronic device and an antenna system thereof. The antenna system comprises a main antenna unit and a parasitic antenna unit. The main antenna unit is an antenna structure having the radiation feature of a current loop antenna, and comprises a feed point, and a first radiation branch arranged on a first main body of an electronic device. The parasitic antenna unit comprises a second radiation branch arranged on a second main body of the electronic device. In a folded state, the first radiation branch and the second radiation branch at least partially overlap each other, the first radiation branch is used for performing magnetic field coupling with the second radiation branch, so as to form current loop radiation on both the first radiation branch and the second radiation branch, and current directions in current loops respectively formed on the first radiation branch and the second radiation branch are the same. In this way, longitudinal currents in the same direction can be excited on a folding floor of the electronic device at the same time, thereby achieving the aims of reducing or eliminating the energy consumed in a folded state and improving the antenna efficiency, and effectively solving the problem of the low-frequency antenna efficiency of the electronic device in the folded state becoming worse.
