Abstract:
This talk will give an overview of the recent research activities in antennas at University of Technology Sydney. Following that, it will focus on a beam-steering conformal transmitarray. For the transmitarray, an ultra-thin transmitarray element consisting of three layers of identical square ring slots is developed. The element has a thickness of 0.508 mm (0.04 wavelength in the free space at 25 GHz), achieving a transmission phase range of 330° with a maximum 3.6 dB loss. The element is then applied to a curved transmitarray conformal to a cylindrical surface fed by a standard gain horn with about a 10-dBi gain. A prototype is fabricated radiating a boresight beam with a peak measured gain of 19.6 dBi. Based on the fixed beam transmitarray, a mechanically beam-steering one is developed.
Biography：
Pei-Yuan Qin received a Bachelor Degree in Electronic Engineering from Xidian University, Xi’an, China, in 2006, and a joint Ph.D. Degree from Xidian University and Macquarie University, Australia, in electromagnetic fields and microwave technology in 2012.
From 2012 to 2015, he was a Postdoctoral Research Fellow in Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia. From 2015 to 2016, he was a Chancellor's Postdoctoral Research Fellow/Lecturer with University of Technology Sydney (UTS), Australia. Since 2017, he is a Senior Lecturer (Permanent Position) with UTS. In 2018, he was a Visiting Scholar with Harvard University. His research interests are in the areas of reconfigurable antennas, reflectarrays, transmitarrays and MIMO communications.
Dr. Qin was a recipient of an Australia Research Council Discovery Early Career Researcher Award. Since 2017, he has been serving as an Associate Editor of the IEEE Antennas and Wireless Propagation Letters.
