Sonny Lee Wins 3rd Place in Student Paper Competition at IEEE International Symposium on Phased Array Systems

Sonny’s paper, “Highly Integrated mmWave Antenna-on-Chip Arrays Using Substrate-Integrated Air Cavities,” won third place in the student paper competition at the IEEE International Symposium on Phased Array Systems (PAST). The paper presents the design, fabrication, and characterization of a 60 GHz beamforming array for 6G high data-rate wireless systems. The proposed silicon-based antenna offers the potential for future wireless system-on-a-chip (SoC) applications better equipped to handle high data throughput. Congratulations Sonny!

Sonny and Thomas Presented at IEEE Phased Array

Two Ph.D. students from the mmWave Antennas and Arrays Laboratory – Seung Yoon (Sonny) Lee and Thomas Williamson – presented their papers at the 2024 IEEE International Symposium on Phased Array Systems & Technology (PAST) held October 15-18 in Boston, MA. Sonny’s paper is titled “Highly Integrated mmWave Antenna-on-Chip Arrays Using Substrate-Integrated Air Cavities”. Tom’s paper is titled “A 10–50 GHz Ultrawideband Low Loss mmWave VO2 based Phase Shifter for Passive Scanning Arrays”.

Walter Disharoon Receives Herbert P. Haley Fellowship

Ph.D. student Walter Disharoon received the Herbert P. Haley Fellowship. Walter joined Georgia Tech as a Ph.D. student in 2021. He joined the mmWave antennas and arrays laboratory in Spring 2022. He won the fellowship for his continued research on VO2-based reconfigurable metasurfaces including a reconfigurable reflectarray and an energy selective surface.  Congratulations Walter!

Ashley Goodnight Receives NSF Fellowship

Undergraduate researcher Ashley Goodnight receives the prestigious NSF Graduate Research Fellowship Program (GRFP). Ashley has been involved in design, fabrication, and test of tunable mmWave transmission lines using phase-change materials. She recently received her B.S. from Georgia Institute of Technology. Ashley will join MIT as a Ph.D. student in Fall 2024. We wish her the very best. Congratulations Ashley! We will miss you!

David West Receives NDSEG Fellowship

Ph.D. student David West receives the prestigious National Defense Science and Engineering Graduate (NDSEG) Fellowship. David joined Georgia Tech and mmWave Antennas and Arrays Laboratory as a Ph.D. student in 2022. He has performed research on VO2-based reconfigurable mmWave devices, including tunable Ka-band polarizers, low-loss switches, mmWave arrays, and periodic structures.  Congratulations David!

Seung Yoon Lee Receives IEEE 2023 Antennas & Propagation Society (AP-S) Doctoral Research Grant

Seung Yoon (Sonny) Lee was awarded the prestigious IEEE 2023 Antennas & Propagation Society (AP-S) Doctoral Research Grant. The grant awards $5000 to only 10 PhD students globally every year to support students in their pursuit of careers in electromagnetics. Sonny’s project aims to develop a highly efficient on-chip antenna array operating in the mmWave band, incorporating low-loss vanadium dioxide (VO­­­­2) switches through monolithic integration. The primary objective is to design, fabricate, and characterize a 60 GHz electronically scanned array for high-speed wireless systems.
