Abstract :
A characteristic impedance de-embedding technique of conductor-backed CPW (CBCPW) lines with probe-tip measurements and with automatic detection of the equivalent reference plane position is presented. The measurements up to 100 GHz, supported by full-wave finite element method (FEM) simulations, indicate some deviations in the extracted values as a result of the conversion to the waveguide modes.
