45) The Input Impedance of a Single Terminated Lossless Transmission Line From a signal point of view, losses are of enormous importance for long or highly dissipative coaxial transmission lines but only relatively important for short microstrip lines in which the attenuation constant can be disregarded. Thus, the microstrip test circuits analyzed here will be considered as lossless a = 0. 46) 27 Analysis of Passive Microstrip Circuits where bl = θ is the electric length of the transmission line under consideration.
