Title:
CONDUCTIVE FILM FOR ANTENNAS, AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/085051
Kind Code:
A1
Abstract:
A conductive film for antennas, said conductive film being obtained by superposing an electroconductive film on a base material that is formed from a polycarbonate resin material containing a polycarbonate resin that contains, as main constituent units, a unit (A) represented by formula (1) and/or a unit (B) represented by formula (2). This conductive film for antennas has bendability and low dielectric characteristics, thereby being capable of forming an antenna having a low propagation loss, while exhibiting excellent adhesion to the electroconductive film. (In formula (1), each of R1 and R2 independently represents an alkyl group having from 1 to 6 carbon atoms, or a halogen atom; and each of R3 and R4 independently represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or a halogen atom.) (In formula (2), each of R1 and R2 independently represents an alkyl group having from 1 to 6 carbon atoms, or a halogen atom; each of R3 and R4 independently represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or a halogen atom; R5 represents a halogen atom, an alkyl group having from 1 to 20 carbon atoms, or a cycloalkyl group having from 3 to 20 carbon atoms; and n represents an integer from 0 to 10.)
