1. (7 pts.) For a microstrip of width w on a dielectric substrate of thickness h and dielectric constant &, the distributed capacitance is C = 102.56 pF/m. After removing the dielectric, the corresponding air capacitance of the microstrip is found to be Cair = 25.64 pF/m. (a) Determine the distributed inductance of the microstrip line. (b) What is the characteristic impedance of the microstrip line? (c) What is the physical length of a N5 microstrip section at f = 3 GHz? (d) Qualitatively indicate how the four parameters given in the table below change with increasing w/h ratio of the microstrip: increases decreases no change Parameter Capacitance per-unit-length Inductance per-unit-length Characteristic Impedance Physical length of a 15 microstrip section
