23. A microstrip line has the per unit length pa- rameters L = 1 nH/m and C = 1 pF/m, also at 1 GHz the substrate has a conductance G of 0.001 S/m. The substrate loss is solely due to di- electric relaxation loss and there is no substrate conductive loss. The resistance of the strip is 0.5 N/m and the resistance of the ground plane is 0.12/m. (a) What is the per unit length resistance of the microstrip line at 1 GHz? (b) What is the magnitude of the characteristic impedance at 1 GHz? (c) What is the conductive attenuation constant in Np/m? (d) What is the dielectric attenuation constant of the line at 1 GHz in dB/m?
