3 The Input Impedance of a Single Terminated Lossy Transmission Line Since the input impedance is a very general parameter representing well the behavior of circuits and transmission lines, this will be used as a reference to compare the analytical, simulated, and measured responses of the test circuits. Thus, the input impedance of a loaded transmission line is derived from the previous theory. 35) from which 25 Analysis of Passive Microstrip Circuits The relation of the reflected and incident voltage wave amplitudes represents a very important figure of merit known as the voltage reflection coefficient.
