Query: Steerable Antennas for Automotive Communication Systems   This research project undertakes a comprehensive analysis of RF beamforming
techniques for design, simulation, fabrication, and measurement of Butler
Matrix and Rotman Lens beamforming networks. It is aimed to develop novel and
well-established designs for steerable antenna systems that can be used in
vehicular telematics and automotive communication systems based on microwave
and millimeter-wave techniques.
