Title:
RADIO WAVE REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2023/127710
Kind Code:
A1
Abstract:
Provided is a radio wave reflector that can reflect radio waves without impairing intensity or damaging the view. This radio wave reflector is for reflecting radio waves. There is a frequency at which the intensity of reflected waves that result from specular reflection of incident waves is at least -30 dB relative to the intensity of the incident waves, and the total light transmittance measured using a D65 standard light source is at least 65%.
