Yuxiao He, a graduate student of Electrical and Computer Engineering, has won the 2nd place in the student paper competition at the 2018 IEEE 11th Global Symposium on Millimeter Waves (GSMM) that was held in Boulder, Colorado, on May 22-24, 2018. Congratulations!
Yuxiao is currently pursuing his Ph.D. degree under Dr. John Papapolymerou, Chairperson and MSU Foundation Professor of Electrical and Computer Engineering. He joined the group in 2016 after receiving his M.S. degree in Electrical Engineering from State University of New York (SUNY) at Buffalo. Prior to his Masters he graduated with B.E. degree in Communications Engineering from the Communication University of China in 2013. His research interests include microwave and RF circuits, additive manufacturing and magnetic nanomaterials in high-frequency applications.
The awarded paper is entitled "A Bi-material Fully Aerosol Jet printed W-band Quasi-Yagi-Uda Antenna". It presents for the first time the successful fabrication of a bi-material, fully printed W-band quasi-Yagi-Uda antenna using the Aerosol Jet printing technology. On top of the Liquid Crystal Polymer host substrate, the ground plane and the metal antenna layer were Aerosol Jet printed with silver ink, while the dielectric substrate was deposited using polyimide. Various sizes of nozzles were used to achieve quality geometry resolution and fast prototyping. The measured S11 was -20 dB at the resonance frequency of 92.7 GHz and matched well with the -31.6 dB of simulated S11 at 94 GHz. Additionally, 7.65 dBi of simulated maximum realized gain and 9 GHz of simulated 3 dB bandwidth was also obtained.
