A rapidly growing demand for fast wireless services calls for wideband communication systems with wideband antennas, which are compact, aesthetically appealing and inexpensive, yet have good performance. With novel concepts, this project aims to produce a new class of antennas that deliver impressive performance (bandwidth and gain) while taking up a dramatically reduced area in a way that was impossible before, increasing a figure-of-merit to up to seven times the state-of-the-art. Their planar geometry and simplicity lead to low cost. This is expected to create new knowledge, design methods and examples, prototypes, test results and guidelines required to design, optimise and make these versatile antennas for emerging robust broadband wireless systems.Read moreRead less

This project aims to establish terahertz measurement capabilities to further Australia's strength and momentum in terahertz research. This will comprise of two terahertz extension modules, working with a dedicated vector-network analyser, and high-precision probes and probe station. The project will enable point-feeding, monochromatic, coherent, and fine spectral-resolution measurement at an atmospheric window of 220-330 GHz. The capabilities are essential for development of two-dimensional materials, active components, waveguides, and antennas towards a common goal of efficient integrated terahertz devices and systems. The project will serve emerging terahertz applications including standoff imaging and short-range high-speed data transmission. This will have broad impact in the areas of surveillance, biomedicine, security, and public safety and well-being.Read moreRead less

This project aims to develop affordable and compact, reconfigurable antenna systems for satellite-terminals. With unprecedented performance, the wide bandwidth of operation, and low cost of production, the resulting antenna systems will act as the ‘enabling’ chip in providing internet connectivity to millions of people, who are unconnected or poorly connected at present. High-speed internet is not a reality outside densely populated areas, even today. The outcomes will close the digital divide, increase Australia’s economic and intellectual standing internationally, generate socio-economic benefits by empowering regional populations, increase the economic viability and remote-jobs outside metropolitan cities, and develop tourism.Read moreRead less
Dual-band antennas with digitally steerable beams made out of multi-state electromagnetic elements. A collection of antennas required for forthcoming wireless systems will be designed, made and tested. They are ideal for wireless on-body medical devices and wireless transmission of high-quality video and high-speed data. These systems will bring great benefits to wireless users and patients, including better quality of life and convenience.

Unconventional antennas from macro- to nano-scales. This research project will develop unconventional radio-frequency antennas for tomorrow's miniaturised multi-function wireless communication systems. It will also extend the principles to resonant nano-structures or 'optical antennas' which offer new perspectives in sensing physics, with the possibility of single molecule detection and identification.
