The Australian government has decided to support the timely rollout of fifth-generation (5G) mobile communication systems due to their potential for producing far-reaching economic and social benefits. This infrastructure rollout requires a quick, efficient deployment of the associated 5G base stations. The integration of 5G antenna arrays into existing 3G/4G base stations would alleviate the substantial cost increases and negative environmental impacts tied to acquiring new sites for them. This project aims to develop the theory and engineering methodologies necessary to successfully address the significant scientific challenges posed by the detrimental interference effects associated with the compact integration of 3G/4G/5G arrays.

This project aims to develop a revolutionary antenna beam steering method. A high-gain antenna with the ability to steer its pencil beam to any direction in two-dimensions within a wide range is an essential part in many telecommunication and defence systems. The project expects to produce compact, low-cost antenna systems with high performance, to circumvent the limitations of existing methods in applications such as providing internet connectivity to those who are unconnected or poorly connected, or data transfer from satellites to earth stations. The proposed technology should significantly improve internet services in regional Australia and connect billions of people worldwide who do not have regular internet access at present.Read moreRead less
Airborne passive radiometer for high resolution soil moisture monitoring. The project proposes to create a novel technology to measure soil moisture. Accurate knowledge of soil moisture profiles at high resolution is important for sustainable land and water management including efficient irrigation scheduling and cropping practices. A passive multi-band soil moisture-measuring radiometer at L-, Ku- and Ka-bands is proposed. The radiometer comprises a three-band shared aperture antenna array, a ....Airborne passive radiometer for high resolution soil moisture monitoring. The project proposes to create a novel technology to measure soil moisture. Accurate knowledge of soil moisture profiles at high resolution is important for sustainable land and water management including efficient irrigation scheduling and cropping practices. A passive multi-band soil moisture-measuring radiometer at L-, Ku- and Ka-bands is proposed. The radiometer comprises a three-band shared aperture antenna array, a receiving electronics, a digital controller and a data logger. The array antenna comprises dual polarised stacked patch elements. Beamforming networks form agile beams to scan the ground. Sensitive radiometer receivers apply brightness temperature downscaling for high resolution. The high-resolution passive radiometer would revolutionise airborne soil moisture monitoring by removing the mechanically steerable bulky and heavy scanheads.Read moreRead less
Empowering terahertz sources with silicon antennas. This Project aims to create dielectric antennas for high-frequency terahertz sources, i.e., resonant tunnelling diodes.

Motivated by their end-use, the Project expects to deliver high-efficiency, high-gain low-profile cavity antennas for free-space operation and Yagi-Uda couplers for guided-mode operation. Silicon will be a key material for both types of terahertz structures to achieve highest efficiency. Effective medium theory will enable performance, functionality, and integrability, while maintaining structural simplicity for cost benefits. The expected outcomes will replace decades-old costly hyper-hemispherical lenses for future terahertz systems in fixed wireless backbone beyond 5G and short-range see-through radar and imaging.Read moreRead less
