Liquid Crystal Reflect Arrays for Electromagnetic Wave

LC device eliminates coverage hole in millimeter wave communication

Overview

・ At millimeter wave communication, there is a concern about increasing coverage hole which is area where the communication becomes impossible.　
・ Therefore, installing the reflect array for all over city that can control the direction of electromagnetic wave is proposed.
・ A conventional reflect array composed of liquid crystal (LC) has problem of slow response.
・ In the invention, reduction of response time is achieved by forming a stripe electrode on　substrate which can be applied vertical and horizonal electric field.
・ The invention is not only expected to apply for reflect arrays, but also phase modulators and phased array antennas.
