Abstract

In this paper a numerical procedure is presented based on the method of least squares (MLS) to synthesize a STEPLINE TRANSFORMER to match two complex impedances over a frequency bandwith for a specified line length. First, the input impedance of a stepline terminated in a load impedance is obtained using the transmission matrices of the line sections and junction discontinuity impedances. Then, an error function is constructed as the sum of the magnitude squared of the difference between the input impedance of the stepline and the generator impedance over discrete frequencies in the desired bandwidth. The error function is then minimized with respect to the stepline characteristic impedances and also separately with respect to the stepline length. This numerical procedure serves as an effective tool for the design of transformers of complex impedances with specified lengths and frequency bandwidths and its implementation reveals uncommon and interesting transformer shapes which best realize matching conditions in the least square sense.
