Size reduction of dielectric-loaded horn antennas combining a Body-of-Revolution (BoR) - FDTD solver and a Genetic Algorithm (GA)

This paper presents an electromagnetic synthesis tool for the design of axis-symmetrical radiating structures has been described. It is based on the combination of a fast BoR-FDTD solver coupled to a real-coded GA. To reduce the computation time, grid-computing techniques have been applied. The implementation has been validated through the synthesis of conical horn antennas loaded with shaped lenses at 60GHz. The proposed designs have shown that a 60% size reduction can be achieved. Experimental results will be presented during the Conference.
