High-Performance Microwave Active Circuits for some Interesting Applications

Thursday, 19 June, 2014 - 08:30 to 10:30

This talk will present an overview of the activities in the microwave group at the University of Colorado, Boulder, followed by a more detailed discussion of a few specific projects: (1) wireless powering for low-power sensor platforms and other wireless powering applications; (2) micro-fabricated G-band frequency-steered antenna arrays for planetary landing radar operating in the 130 to 180GHz frequency range; (3) high-efficiency microwave transmitters for non-constant envelope communication and radar signals, from 2.5kW to 5W in power level, and 450MHz to 10GHz in frequency;  and time-permitting, microwave radiometers for internal body thermometry. Related to the first topic, for example, ISM-band (915 MHz, 2.45GHz and 5.8GHz) rectennas integrated with power management circuitry and low-power wireless sensors will be described. Additionally, rectenna arrays for various applications ranging from broadband 2-18GHz harvesting to 1.96GHz cellular base-station power recycling will be shown.
