Synthesizing layered dielectric cylindrical lens antennas

Cylindrical lenses are attractive antennas launching multiple fan-beams, each of them originating from one primary feed ; the beams are scanned by moving the feed around the surface of the lens or by switching between one feed and an adjacent one. In this paper we describe an optimization technique for synthesizing cylindrical layered dielectrical lenses by the algorithm based on the spectral-domain analysis approach coupled to the PSO (Particle Swarm Optimization) global optimization technique.
