Abstract

In this paper, the authors have obtained the transmission losses by measuring microstrip lines and post-wall waveguides of different lengths and estimated the loss per unit length. These losses have been analytically derived by different closed formulas and compared with the measured values. The effective conductivity and complex permittivity by WG mode resonator method have been quantitatively confirmed in millimeter wavebands. The efficiency due to the transmission loss has been discussed.
