Title:
ANTENNA APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/063179
Kind Code:
A1
Abstract:
The present application provides an antenna apparatus and an electronic device. The antenna apparatus comprises an antenna module and a radome. The antenna module is used to receive and transmit, from/towards a preset direction range, radio frequency signals of a preset frequency band. The radome is provided spaced apart from the antenna module, and the radome is located within the preset direction range. The radome comprises a substrate and a resonant structure carried on the substrate. The substrate is used to pass radio frequency signals of a first frequency band among preset frequency bands, the resonant structure is used to adjust a pass band width of the substrate for the radio frequency signals of the preset frequency band, so that the radome can pass radio frequency signals of a second frequency band among the preset frequency bands, wherein the bandwidth of the second frequency band is greater than the bandwidth of the first frequency band, and the radio frequency signals of the second frequency band include radio frequency signals of the first frequency band. The antenna apparatus provided in the present application has a large bandwidth, and an electronic device using the antenna apparatus has good communication performance.
