July 9th, 2014: Congratulations to Nathan Jastram for winning the 1st place Best Student Paper Award at the 2014 IEEE APS/URSI Symposium for his paper: Wideband Multibeam Millimeter Wave Arrays. 

Antenna Research Group (ARG)

The Antenna Research Group at the University of Colorado Boulder is housed in the Department of Electrical, Computer, and Energy Engineering. ARG’s research specializes in antenna theory and design with emphasis on frequency independent and wideband antennas; development of passive millimeter-wave components, systems, and electronic warfare front-ends; low-cost fabrication of RF systems; simultaneous transmit and receive; and multi-physics, multi-scale modeling.

Current Projects

  • Enabling Technologies for High-Power Wideband Millimeter-wave Space-Constrained
    Nate and David are developing components and subsystems that will enable high-power, low-loss and dispersion, performance in 18-45GHz range for small EW platforms. 
  • High-Power Subhyperband Antennas and Arrays
    Mohamed and Jaegeun are researching fundamental physics that will enable miniaturization of high-pulsed power antennas and their performance in time and frequency domains.
  • Low Profile HF Antennas for Vehicles on the Move
    Maxim, Saurabh, and Sushant are developing electrically small, low-profile vehicular antennas with wide bandwidth (>24kHz) for all 3 HF modes with emphasis on NVIS.

Anechoic Chamber

  • NSI 700s-30 Fully Automated and Computer controlled system
  • Spherical Near-field 1-75 GHz
  • Far-field from 1-110 GHz
