August 4, 2015: Congratulations to Jaegeun Ha for winning the best student paper award at the 2015 ASIAEM Conference.

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 millimeter-wave direction finding systems; simultaneous transmit and receive (STAR); broadband antennas, low-cost micromachining alternatives; frequency independent and wideband antennas; development of passive millimeter-wave components, systems, and electronic warfare front-ends; low-cost fabrication of RF systems; and multi-physics, multi-scale modeling.

Current Projects

  • SPEAR Front-End
    Elie, Prathap, Varun, and Mohamed are developing a 90:1 wideband mono/bi-static dual-polarized STAR system.
  • Embarkable Decoy
    Conrad and Nate are working on the mmW decoy platform.
  • Circulator in Aperture (CIA)
    Ehab, Bryan, and Maxim are investigating front-end configuration for wideband STAR and millimeter-wave Luneburg lenses. 
  • Flexible RF System for Space Constrained Decoys
    In collaboration with Professor Popovic, Sara and Muhannad are looking into fundamental and applied solutions for extending decoy operation through the W-band. 
  • 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, Sushant, Brad, Matt, Milica, and Chad are developing, constructing, and testing 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
