Title:
ANTENNA ASSEMBLY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/000731
Kind Code:
A1
Abstract:
Provided are an antenna assembly and an electronic device. The antenna assembly comprises: a dielectric structure, wherein the dielectric structure has a first region, a second region and a third region sequentially connected in a preset direction, the first region is used for generating a first phase change amount for a radio-frequency signal, the second region is used for generating a second phase change amount for the radio-frequency signal, the third region is used for generating a third phase change amount for the radio-frequency signal, and the second phase change amount is different from the first phase change amount and the third phase change amount; and at least one antenna module, wherein the at least one antenna module is arranged opposite the dielectric structure, and in the preset direction, the center position of the at least one antenna module is shifted by a preset distance with respect to the center position of the second region, so that the main lobe direction of the radio-frequency signal transmitted by the antenna module deviates from the normal direction of the antenna module by a preset angle. Provided are an antenna assembly and an electronic device capable of improving antenna signal transmission quality and a data transmission rate.
