Abstract:

This thesis presents analytical and numerical techniques for analyzing the scattering from a planar equiangular spiral antenna loaded at its terminals. The scattering matrix for the loaded antenna is derived as a function of the antenna load impedance. This derivation is the result of an analytical study of the voltagecurrent relationship at the antenna terminals along with an application of a multiport analysis of the scattering problem. A numerical technique is also developed that utilizes at different wavelengths common elements of the generalized impedance matrix of the moment method solution. This technique provides for rapid computation of the scattering properties of the spiral antenna across a band of frequencies.
