Document Type and Number:
WIPO Patent Application WO/2021/212975
Kind Code:
A1
Abstract:
Provided in the present application are an antenna apparatus and an electronic device. The antenna apparatus comprises: a dielectric substrate, an antenna coil, and a conductive element. The antenna coil is disposed on the dielectric substrate, the antenna coil comprises a winding center part, and at least one first conductor segment and at least one second conductor segment that are disposed on two opposite sides of the winding center part, the first conductor segment and the second conductor segment being in series connection. The conductive element is disposed on the dielectric substrate, the conductive element is arranged opposite to the antenna coil, and the orthographic projection of the conductive element on the dielectric substrate covers the orthographic projection of at least part of the first conductor segment on the dielectric substrate. The conductive element is electrically connected to the first conductor segment, and the magnetic field produced by the conductive element is used to cancel out the magnetic field produced by the first conductor segment. The second conductor segment in the antenna apparatus provided in the present application acts as a main radiator that has excellent communication capabilities.
