Comparison of Exact Analysis and Steplines Approximation for Externally Excited Exponential Transmission Line


Electerical Engineering, Iran University of Science & Technology


In the present paper, the problem of externally excited exponential transmission line hasbeen solved analytically in frequency domain using a simple approach. Then steplines approximationas a first order approximation for the problem of externally excited nonuniform transmission lines ingeneral and exponentially tapered transmission line (ETL) as a special case has been presented.Finally the two approaches are compared and some useful results are obtained to show when the twomethods are equivalent.
