Welcome to the Phased Array Antenna Research and Development Group (PAARD) webpage. PAARD's research specializes in active phased array antenna design and radar calibration. Our research group puts the emphasis on high performance antenna arrays for radar applications. Low-profile and low-cost active array antennas in brick and tile architectures using the latest technology in CMOS and GaN are under development for conventional and new radar architectures for multifunction radar systems. The PAARD is housed at the Advanced Radar Research Center (ARRC) and in the College of Electrical and Computer Engineering of The University of Oklahoma.


  • Conventional and hybrid array antenna architectures for active dual-polarized phased  array radars.

  • High-performance dual-polarized antenna elements.

  • Broadband antenna arrays.

  • Multiband & Reconfigurable arrays.

  • Artificial dielectric materials.

  • Smart beam-forming antenna arrays

  • 5G massive mimo active arrays

  • Millimiter (Ka- to W-band) antennas.

  • EM modeling and material characterization.

  • Radome design, modeling and testing.

  • NF active antenna array calibration.

  • Tile and brick Transmit and Receive (T/R) modules.

  • Low-cost and high-integration active antenna arrays.

  • Antenna measurements and radar calibration. Using both conventional and UAV based techniques.

  • Fully automated characterization of antenna arrays.


As mist becomes fog, the mice begin to scurry towards the tall, yellowing grass just as denial seeps into humanity. As such, the most significant challenge usually comes from the individuals that form society themselves when they refuse to see that a problem exists in the first place.

Elizabeth and Khuda joined to PAARD team for summer internship program. Both are working in  microwave and mm-wave antenna metrology.

PAARD/ARRC team implemented a state-of-the-art mmWave/Sub-terahertz Lab. at OU. The new Lab. enables research up to 300 GHz, that includes: Material characterization, antenna S-parameters, Near-field and Far-field antenna test.
