Radiation, Multimode Propagation, and Substrate Modes in W-Band CPW Calibrations



Dylan F. Williams, Franz-Joseph Schmuckle, Ralf Dorner, G.N. Phung, Wolfgang Heinrich, Uwe Arz


We investigate the degradation of the accuracy of coplanar waveguide calibration standards at higher frequencies due to multi-mode propagation, substrate modes, and radiation. Based on a typical calibration substrate, we investigate these effects and their impact on vector-network-analyzer calibrations at W-band.
