Abstract : This report deals with an experimental investigation of the use of a digital computer to synthesize impedance-matching networks for arbitrary load immittances. The load immittance is described only in terms of measured immittance data, and not by a model (network). The computer algorithm developed will select the correct form of the matching network, as well as the element values, for an impedance match which is close to the optimum for the specified number of elements in the matching network. The problem is formulated for solution by digital computer as a multidimensional minimization problem. The most suitable objective function for the minimization process to operate upon is investigated. Along with a discussion of several known minimization techniques applicable to the problem, a new technique is described which performs better than previously available methods on some problems. Finally, some examples of the use of the impedance-matching technique are given for typical antenna immittances. (Author)
