Propagation constant of a Transmission line Characteristic Impedance of a Transmission line: The characteristic impedance of a transmission line is defined as the ratio of the positively travelling voltage wave to the current wave at any point on the line. Lossless Transmission line Input impedance on a transmission line Stub Matching In a transmission line, if the load is mismatched and a reflected wave exists on the line. However, for maximum power transfer, it is desired that load be matched to the transmission line, Stub is a line matching device An open-circuited stub radiates some energy at high frequencies. Consequently, shunt short-circuited stubs are preferred. Stub has the same characteristic impedance as the main line.
