DIELECTRIC, INSULATED WIRE, COAXIAL CABLE, AND DIELECTRIC PRODUCTION METHOD

摘要

A dielectric is characterized in that the main component is a polytetrafluoroethylene resin, the effective relative dielectric constant is 1.8 or less, and the dulometer hardness is A50 to D36. An insulated wire exhibits a low attenuation in the high-frequency band and an excellent transmission characteristic. The adhesion of the center conductor to the dielectric and strippability are excellent. A desired characteristic impedance is obtained accurately. The characteristic impedance at a bent portion does not vary.
