Abstract
The dielectric properties at millimeter-wave band(MMW) of commercially available LTCC substrate were measured using cavity resonance method. A6S substrate from Ferro has best dielectric properties at MMW bands, and the other substrates also have good dielectric properties. CBCPW (Conductor backed coplanar waveguid) lines for MMW were designed and measured. The transmission losses of CBCPW lines on LTCC substrate with tand less than 0.002 were 0.1dB/mm. As the tand of LTCC substrate increases to 0.004, the losses of CBCPW lines at 60 GHz increase to 0.15dB/mm. However, this transmission loss of 0.15dB/mm is sufficiently low in the application of LTCC as a packaging technology at MMW band. As expected, the transmission losses of lines were critically dependant on the dielectric properties of the substrate used.
