Reconfigurable intelligent surface including multiple unit cells

Abstract

A 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A reconfigurable intelligent surface (RIS) including a plurality of unit cells in a wireless communication system includes a first pattern included in a top layer of a unit cell included in the RIS, a second pattern included in a bottom layer of the unit cell included in the RIS, and at least one switch configured to electrically ground or short the first pattern and the second pattern in response to a command for determining whether the unit cell included in the RIS operates as a transmissive RIS or a reflective RIS.

Dependencies are inferred from the claim text.
