The purpose of this thesis is to investigate the use of Conformal Subdomain Basis Functions (CSBF) in the Method of Moments (MM) solution of a thin wire scatterer. The effect of using CSBF on the computed current and the scattered field is investigated by formulating and coding the MM solution for a thin wire loop and comparing the computed results for various loop sizes to measured data and two other MM codes. Significant reduction in the number of segments (and computer memory requirements) are found for loops with circumferences of less than one to two wavelengths for plane wave incidence. From these results, it is concluded that the use of CSBF will significantly reduce the number of segments required for the MM solution of a spiral antenna.
