AI Technical Summary

Technical Problem

The reflective meta surface experiences reduced reflection performance due to current formation between metal patches and exhibits significant variation in reflection performance based on the on/off state of switching elements, particularly in high-frequency bands.

Method used

The reflective meta surface is designed with a specific structure that includes a first patch, a second patch spaced apart from the first patch, a switching element between them, and a ground layer. The patches are arranged with varying intervals and widths to minimize current-induced magnetic effects and optimize reflection performance.

Benefits of technology

This configuration reduces the magnetic system's impact on reflection performance, stabilizes the reflection performance across different switching states, and enhances the overall reflection performance, thereby improving wireless communication coverage.

Abstract

This reflective metasurface comprises: a first patch formed on a first surface of a substrate; a second patch formed on the first surface of the substrate and arranged to be spaced apart from the first patch; a switching element disposed between the first patch and the second patch; and a ground layer formed on a second surface of the substrate. A first spacing and a second spacing are provided in a region where the first patch and the second patch face each other. The switching element is disposed in the first spacing, and the second spacing is formed to be wider than the first spacing.
