Title:
ANTENNA DEVICE AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/057907
Kind Code:
A1
Abstract:
Disclosed in the present application is an antenna device. In the antenna device, a scatterer structure comprising a Q layer dielectric substrate is disposed above an antenna array. A target region of the Q layer dielectric substrate comprises resonators having an axially symmetric structure, the quantity and distribution thereof satisfying certain conditions. At least one of the resonators is shared by a first antenna unit and an adjacent second antenna unit on the antenna array in a range corresponding to the target region. By disposing a scatterer structure above an antenna array, the technical solution of the present application reduces spatial correlation between antenna units, such that beam signals arriving at the antenna array can be better differentiated, signal superposition interference is reduced, and the MIMO performance is improved.
