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. The reflection phase can be controlled by changing the distance between the reflective element and the ground plane of a reflector. Therefore the reflection angle can be controlled by designing the configuration. In this paper, the measurement results of a prototype of the meta-surface reflector are shown.
The distance between the ground plane and the reflective element of the reflector can be controlled by using servo motor unit.
