In the last decade increasing attention and efforts have been placed on designing reconfigurable antennas, especially those utilising substrate-integrated technology which provides many advantages such as low-loss, low cost and ease of circuit integration. This seminar introduces a new type of reconfigurable antenna based on a substrate-integrated cavity with very wide frequency tuning range and highly stable radiation patterns. Using 3 varactors with measured capacitance from 0.149 pF to 1.304 pF, the antenna has been designed and optimized based on a theoretical model to operate from 2.60 GHz to 3.95 GHz, i.e. S-band or WR-284 waveguide band.
Nghia Nguyen-Trong received a Bachelor degree with a first class Honour in electrical and electronic engineering from the University of Adelaide in 2013. He is currently working towards a PhD at the University of Adelaide with the Adelaide Applied Electromagnetic Group. His research interest includes leaky-wave antennas and reconfigurable antennas. He received the Governor’s International Student of the Year of South Australia award in 2012. He was one of the recipients of the best student paper award at the 2014 International workshop on Antenna Technology (iWAT).
