Seminar: ECE Faculty Candidate
Wednesday March 8th 11:00 - 11:50am KEC 1005 Nader Behdad PhD. Candidate Department of Electrical Engineering and Computer Science University of Michigan Multifunctional Antennas for Wireless Integrated Micro-Systems The goal of the Center for Wireless Integrated Micro-Systems at the University of Michigan is to develop functional micro-systems combining micro-power integrated circuits, wireless interfaces, and Micro-Electro-Mechanical Systems (MEMS) in a platform suitable for a wide range of applications. One example of such an application is a miniature integrated environmental monitoring system that uses an integrated wireless interface to transmit the recorded data using radio frequency signals. Such systems require electrically small antennas that can easily be integrated with their RF transceiver circuits and provide adequate bandwidth for the system to operate. Developing viable methods for designing such antennas is the main subject of this presentation. The presentation will begin with an overview of a number of antenna miniaturization techniques and examples of miniaturized antennas that are 15 to 20 times smaller than their commercial counterparts will be presented. The focus of the second half of the presentation will be on developing methods for bandwidth enhancement of such antennas. In particular, a method for designing electronically reconfigurable antennas will be studied in detail. The application of this technique in the design of an antenna with two operating bands that can be tuned independently over a wide frequency range will also be discussed and measurement results of this highly tunable dual-band antenna will be presented. Biography: Nader Behdad received the Bachelor of Science degree in Electrical Engineering from Sharif University of Technology in September 2000 and the Master of Science degree in Electrical Engineering from The University of Michigan, Ann Arbor, in 2003. He is currently working towards the Ph.D. degree at the Department of Electrical Engineering and Computer Science of the University of Michigan, Ann Arbor. Mr. Behdad is the recipient of the best student paper award in the Antenna Applications Symposium held in Monticelo, IL, in September 2003, winner of the second prize in the student paper competition of the USNC/URSI National Radio Science Meeting in Boulder, CO, in January 2004, and the recipient of the Horace H. Rackham Predoctoral Fellowship from the Rackham School of Graduate Studies of The University of Michigan in 2005. _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
