Graduate Courses
ECE 5973: Phased Array Antenna
Semester: Fall
Graduate course will provide the basic knowledge and the most important design trade-offs of phased array antennas that are used for civil and military applications. This class will put emphasis on the critical evaluation of the performance of phased array antenna systems, especially for atmospheric applications. Factors that are important for high-performance radar and communication systems, such as scanning performance, phased array antenna architectures, feed-networks, mutual coupling, infinite and finite active arrays, T/R modules and technologies, multibeam arrays, adaptive arrays and sidelobe cancellers, will be introduced.

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.

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.

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!

2020 "the COVID year" was not easy at all. Our lab was closed for months, and working from home was challenging. Students kept working day and night to get work done and move on to the next steps of their careers. There is not more gratification for a professor than to see students finishing one of the biggest milestones in their lives. Five of my students graduated successfully this year. Congratulations!!! I'm very proud of all of you!!!

Lab. session of 2020 Phased Array Antenna class at OU. Proud of my Lab. session of 2020 Phased Array Antenna class at the University of Oklahoma (OU). In this class, six active phased array antenna modules in S-band were developed by the PAAARD team. Each module has a dual-polarized S-band passive array, T/R modules, beam-former a 2-port VNA, RF probes, RF cables, cal-kit, etc. The students have the opportunity to learn how to measure mutual coupling and calibrate in near-field the array excitation using fundamental concepts learned during class. Later the validate calibration in NF or FF chamber at the RIL.
