RF and Millimeter-wave Antennas

RF and Millimeter-wave Antennas

Antenna systems are developed to operate from 100 kHz to 150 GHz for radar, wireless communications, and wireless charging applications. Recent efforts emphasize wideband designs for ultra‑wideband radar and millimeter‑wave solutions for automotive radar. Elliptical resistively loaded vee dipoles (0.4–6 GHz) and compact, lightweight Vivaldi antennas (0.3–50+ GHz) have been designed, fabricated, and tested for ultra‑wideband radar systems. Low‑sidelobe, high‑gain antennas for millimeter‑wave automotive radar have also been created.

Current projects

  • Development of compact, lightweight, high‑gain wideband antennas
  • Development of millimeter‑wave on‑chip antennas and on‑chip antenna measurement techniques
