Abstract :
The antenna as an anisotropic boundary value problem was first considered by Cheo, Rumsey and Welch[1] in their solution to the frequency independent antenna problem. The theoretical results so obtained not only displayed the expected nature of an equiangular spiral antenna, but also closely agreed with actual experimental measurements. Therefore, the directionally conductive surface as a mathematical model of radiator is indeed a potentially powerful approach to antenna analysis. The present paper is a theoretical investigation of the solutions of a class of spherical spiral antennas.
