HighPermittivity TapeTransmission LineforMillimeter-Wave Integrated Circuits

A newtransmission medium, whichconsists ofhigh permittivity tapes inserted inahorizontal mid-plane ofabelow cut-off parallel metalplate waveguide, wasproposed for millimetre-wavelength. This guide hasadvantage suchaswide bandwidth of50% foruseofhighpermittivity tapewitha relative dielectric constant of24.Moreover this guide exhibits lowtransmission loss, measured tobe3dB/mat50GHz.
