Title:
IMPEDANCE MATCHING FILM AND RADIO WAVE ABSORBER
Document Type and Number:
WIPO Patent Application WO/2021/049284
Kind Code:
A1
Abstract:
An impedance matching film 10a has a plurality of openings 11 regularly formed along a main surface 10f of the impedance matching film10a. For the impedance matching film 10a, a value ρ/t, obtained by dividing a resistivity ρ of a material forming the impedance matching film 10a by a thickness t of the impedance matching film 10a, is 1-300 Ω/□.
