Title:
METASURFACE UNIT AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/060510
Kind Code:
A1
Abstract:
The embodiments of the present disclosure belong to the technical field of communications. Disclosed are a metasurface unit and an antenna. The metasurface unit comprises: a metal radiation patch with a notch, an upper-layer dielectric plate, a metal ground layer, and a lower-layer dielectric plate, which are sequentially arranged from top to bottom; and a feed structure, wherein one end of the feed structure is connected to the metal radiation patch, and the other end of the feed structure penetrates a feed through hole and is arranged on a bottom layer of the lower dielectric plate; the feed through hole sequentially penetrates the upper-layer dielectric plate, the metal ground layer, and the lower-layer dielectric plate; and the metal radiation patch may rotate around a central axis, such that different angles of included angles between the notch and the positive direction of an X-axis correspond to different polarization states. Therefore, metasurface units in different polarization states can be obtained by means of adjusting an angle between a notch of a metal radiation patch and the positive direction of an X axis, such that a polarization isolation relationship can be directly achieved between different sub-arrays of an antenna based on a metasurface, thereby reducing crosstalk between sub-flows, and improving data flow transmission efficiency.
