An efficient integral transform technique of a singular wire antenna kernel

This paper presents an efficient integral transform technique for evaluatin g the singular part of the scalar and vector potentials due to a uniform cu rrent subdipole. By performing several transformations, the original double integral 1/R-s with a singular kernal can be represented as a finite one-d imensional integral whose integrand possesses an analytically integrable lo garithmic singularity. The results of the newly driven integral are compare d with those using other available numerical methods and checked the validi ty of the proposed method.
