Title:
ANTENNA DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/017777
Kind Code:
A1
Abstract:
An antenna device and an electronic device are provided. The antenna device includes an antenna radome and an antenna module. The antenna radome includes a dielectric substrate and a resonance structure carried on the dielectric substrate. The antenna module is spaced apart from the antenna radome and configured to perform at least one of receiving and transmitting a radio frequency signal of a preset frequency band in a radiation direction which is directed toward the dielectric substrate and the resonance structure. The resonance structure has an in-phase reflection characteristic for the radio frequency signal of the preset frequency band, and a distance between a radiation surface of the antenna module and a surface of the resonance structure facing the antenna module is determined by a reflection phase difference of the antenna radome and a wavelength of the radio frequency signal of the preset frequency band transmitted in air.
