We present an air-gapped microcoaxial transmission line fabricated on low resistivity silicon substrate (ρ = 10 Ω·cm). The transmission line is based on a damascene copper process and has demonstrated superior microwave properties of low attenuation (<0.02 dB/mm) and a low and constant effective...
