In order to meet the need of radio-on-chip, on-chip antennas are preferred. However, conventional
CMOS on-chip antennas suffer from their poor radiation efficiencies because of the low resistivity and high permittivity of the silicon substrate. In this talk, innovative broadband high-efficiency on-chip
antennas fabricated using a standard 0.18-μm CMOS process with an artificial magnetic conductor
for 60-GHz applications will be addressed. In the meantime, antennas-in-package are still popular for
radio-in-package solutions. Integrated broadband antenna arrays using the LTCC technology for 60-
Ghz applications will be discussed. I would also briefly introduce my other research activities including MMIC device modeling and designs, wireless power transmission for implantable devices and patch antennas with broadband feed networks.


Yong Xin Guo joined the Department of Electrical and Computer Engineering, National University
of Singapore, as an Assistant Professor in February 2009. He received the Ph.D. degree from City
University of Hong Kong in electronic engineering in 2001. From July 2004 to January 2009, he was an adjunct Assistant/Associate Professor of the National University of Singapore. From September 2001 to January 2009, he was with the Institute for Infocomm Research, Singapore, as a Research Scientist.
He has authored or co-authored 94 international journal papers and 110 international conference
papers. Thus far, his publications have been cited by others more than 800 times and the H-index is
17 (source: Scopus). He holds one Chinese Patent and one U.S. patent. His current research interests include low-temperature co-fired ceramics-based system-on-package technology, microwave circuits, and MMIC modelling and design, microstrip antennas for wireless communications, implantable/wearable antennas and RF energy harvesting, silicon-based millimetre-wave/THz on-chip antennas.
He was a recipient of the Young Investigator Award 2009, National University of Singapore.
