RF and Millimeter-wave Antennas

Our group develops antennas operating from 100 kHz to 150 GHz for application in radar, wireless communications, and wireless charging systems.  Our recent research focuses on wide bandwidth antennas for ultra-wideband radar and millimeter-wave antennas for automotive radar. Using novel design techniques, we have designed, fabricated, and tested elliptical resistively loaded vee dipoles (0.4-6 GHz) and compact and light-weight Vivaldi antennas (0.3 – 50+ GHz) for ultra-wideband radar systems. Additionally, we have developed low sidelobe and high gain antennas for millimeter-wave automotive radar.  Our current projects include:

            •    Development of compact, light-weight and high gain wide bandwidth antennas 

            •    Development of millimeter-wave on-chip antennas and on-chip antenna measurements
