Title:
METHOD FOR IMPROVING RADIO WAVE TRANSMITTANCE OF MEMBER
Document Type and Number:
WIPO Patent Application WO/2024/062705
Kind Code:
A1
Abstract:
This method is for improving the radio wave transmittance at a frequency of 77 GHz of a member having a base material containing resin, the method being characterized by comprising stacking a film on the member, and in that the film has a thickness of 50 to 10,000 μm, a refractive index of 1.3 to 10, and a surface roughness (arithmetic average roughness Ra) of 0.01 to 2.0 μm.
