Title:
METASURFACE UNIT AND BASE STATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/179306
Kind Code:
A1
Abstract:
Provided in the present application are a metasurface unit and a base station thereof. The metasurface unit comprises: a resonant unit (100), wherein the resonant unit (100) is configured to receive two paths of polarized incident signals, or, to radiate two paths of polarized reflection signals; a power divider (200), wherein the power divider (200) is connected to the resonant unit (100), and the power divider (200) is configured to combine, into a combined signal, the two paths of polarized incident signals, which are input by the resonant unit (100), and/or, divide an input reflected signal into the two paths of polarized reflection signals and output same to the resonant unit (100); and a phase shifter (300), wherein the phase shifter (300) is connected to the power divider, and the phase shifter is configured to perform phase modulation on the combined signal, which is input by the power divider (200), and output, to the power divider (200), the reflected signal, which is obtained by performing the phase modulation.
