MoM analysis of the pin-fed network for a radial line planar antenna

This paper proposes a numeric procedure that enables the iterative design of the radial line pin-fed network included into the optimization loop. For reliable results of the pin´s self impedance the end effect need to be considered, especially for the long pins. By including the end effect in the mutual impedance calculation the accuracy of the results may be further improved. The theoretical analysis is verified by a MATLAB code. The program enables analysis of the radial line feed network with arbitrary number of probes.
