Room location: ACES 2.302

Date:  April 18, 6:00 to 8:00 pm

Talk Abstract: This talk summarizes the recent work on phased arrays starting from the lower frequency chips at 6-12 GHz, and passing by the satellite communication chips at 6-22 GHz, and ending by the short-range communication chips and car radar chips at 60 GHz and 77-81 GHz. Different topologies will be covered: RF phase shifting, IF phase shifting, LO phase shifting, and and digital beamforming, with the pros and cons for each topology. Also, wafer-scale integration and the use of efficient on-chip antennas at 30 GHz and above will be presented. Phased-array systems from industry and academia will be covered in detail.

Biography:  Prof. Gabriel Rebeiz is the Wireless Communications Industry Chair Professor at the University of California, San Diego. He is an IEEE Fellow, an NSF Presidential Young Investigator, an URSI Koga Gold Medal Recipient, IEEE MTT 2003 Distinguished Young Engineer, and is the recipient of the IEEE MTT 2000 Microwave Prize, the IEEE MTT 2010 Distinguished Educator Award and the IEEE Antennas and Propagation 2011 John D. Kraus Antenna Award. He is also the recipient of the 1998 Amoco Teaching Award given to the best undergraduate teacher at the University of Michigan, and the 2008 Jacobs ECE Teacher of the Year Award at UCSD. His group has lead the development of complex RFICs for phased array applications from X-band to W-band, culminating recently in wafer-scale integration with high efficiency on-chip antennas. His phased array work is now used by most companies developing complex communication and radar systems. He has graduated 50 PhD students and 16 post-doctoral fellows, and currently leads a group of 20 PhD students in mm-wave RFIC, planar mm-wave antennas and terahertz systems, microwave circuits, RF MEMS, tunable networks, and is the Director of the UCSD/DARPA Center on RF MEMS Reliability and Design Fundamentals.
