Title:
RADIO WAVE REFLECTIVE ELEMENT USING LIQUID CRYSTAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/188734
Kind Code:
A1
Abstract:
This reflective element comprises common electrodes that are arrayed in a matrix shape at intervals in one direction and in a direction intersecting the one direction, bias electrodes that are arrayed so as to overlap with the common electrodes in a plan view, a liquid crystal layer between the common electrodes and the bias electrodes, and common wires that connect adjacent common electrodes in the array of common electrodes, and the length of the common wires is half the apparent wavelength λg of a radio wave having a specific wavelength λ when the radio wave having the specific wavelength λ propagates through the liquid crystal layer.
