Kathleen L. Melde formerly Virga) joined the faculty of UA Electrical and Computer Engineering in 1996 with extensive experience in modeling, fabrication and measurement of the performance of antennas, antenna arrays, high-density microwave circuits, and high-speed packaging interconnects. Prior to the University of Arizona, from 1985 to 1996, she worked in the Radar Systems Grouat Hughes Electronics in California. Melde is known for her contributions to the design and development of antennas and transmit-receive, or T/R, modules for airborne phased and active arrays. She has more than 90 publications, 5 U.S. patents, and has been an expert witness and consultant in the area of RF circuits and antennas. Her current projects include tunable RF front ends for cognitive radio, high-speed electronics packaging, on-chiantennas, and antennas for wildlife tracking.
