Title:
ANTENNA ASSEMBLY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/207277
Kind Code:
A1
Abstract:
An antenna assembly (10) and an electronic device (1) are provided according to the present disclosure. The antenna assembly (10) includes an antenna module (100) and a bandwidth matching layer (200). The antenna module (100) is configured to transmit and receive, within a preset direction range, a millimeter wave signal in a target frequency band. The bandwidth matching layer (200) is spaced apart from the antenna module (100), and at least part of the bandwidth matching layer (200) is disposed within the preset direction range. The bandwidth matching layer (200) is configured to match an impedance of the antenna module (100) to an impedance of free space to enable an impedance bandwidth of the antenna module (100) in the target frequency band when the bandwidth matching layer (200) is provided to be greater than an impedance bandwidth of the antenna module (100) in the free space.
