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.

RESEARCH INTEREST

  • 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.

Alexis Oblitas a PAARD/ARRC/OU Intern during COVID crisis



Alexis Oblitas a PARRD/ARRC undergrad intern of the University of Oklahoma complete successfully a fully-automated RF scanner for active phased array antenna test and calibration.  Alexis a Peruvian student in Electrical Engineering from "La Universidad Peruana de Ciencias Aplicadas (UPC)",  arrived at Norman Oklahoma, on Jan. 6th of  2020 to be an intern working under the supervision of Dr. Jorge Salazar in research related to phased array antenna technology.  Due to the COVID crisis, Alexis stays at OU for almost 12 months. During this time, Alexis did an extraordinary job integrating sensors with graphical interfaces. The video below corresponds to his last project performed from Sept.- Dec. 2020. He integrated and active phased array antenna, and developed and an RF scanner using a robotic arm and VNA to test and calibrate the active phased array antenna. Great job Alexis!
