Investigating the Behaviour of Lossy Transmission Lines in Communication Systems

This paper investigates the behavior of lossy transmission lines used in communication systems using a lossless transmission line as a case study. It has been the usual practice to skip the detailed study of the lossy transmission line theory by reducing it to the low-loss approximation. Although this is valid in the most common practical cases, however, the study of the general lossy case becomes very important due to the fact that it makes possible a better and deeper understanding of the physical effects associated to general losses. This paper deals with the analysis of some important parameters involved in the general lossy transmission line theory using MATLAB thus improving the understanding of the effects of losses on general transmission line performance. From the results obtained, it is observed that the phase shift really determines the difference between the Heaviside and the low-loss behaviors as there is an increasing mismatch in the line and load voltages as the losses increases.
