A Study on Controlling the Direction of the Scattering Pattern on Meta-Surface Reflector

Abstract

In a wireless environment where radio waves are transmitted and received, the location and size of the communication area and dead zone may change depending on the passage of time and various conditions. To improve the wireless area, using a meta-surface reflector which reflect the radio waves to the coverage hole is considered. In this paper, a 2.45GHz band meta-surface reflector was proposed. The reflection angle of this reflector can be dynamically controlled by designing a unit cell configuration which change the reflection phase.
