Abstract :
In this work we present a closed-form solution for the electromagnetic radiation of a prolate or oblate spheroidal antenna. The problem is solved using a shape perturbation technique, allowing a closed-form solution which is valid for small eccentricities of the spheroid. We validate our approach by comparing with the full wave solution and present numerical results for radiation patterns.
