Scanning vehicular lens antennas for satellite communications

This paper presents technique for designing hemispherical dielectric lens antennas for satellite communications enclosed in protective radome based on spectral domain analysis approach. The analysis technique is coupled with the global optimization technique (namely the particle swarm optimization algorithm), to allow optimization or synthesis of that kind of antennas. The developed tool is used to synthesize vehicular antenna structures and study the influence of radome on radiation pattern.
