Effective Conductivities for Both Sides of Copper Foil Coating Surface of Dieffectric Substrate at 60GHz
It was found out that conductivities of both sides of copper foil coating dieffectric substrate have different values at centimeter frequencies since the one side of surface of the dieffectric substrate is roughened due to tight copper-coating 1. Having this fact in mind, we evaluated the effective conductivities of both sides of copper foil by measuring Q-factors of an NRD guide resonator at millimeter-wave frequencies 2. It was obvious that the effective conductivities of the both surfaces decreased by about 10 percents compared with that of the standard copper balk at 60 GHz band.
