Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distribut ....Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distributed network of nodes can create a detailed picture of the surrounding radio-frequency (RF) environment: the nodes can work together to map the “RF weather”. In this project we will design advanced sensing and localisation methods to accurately map the RF spectrum, and then exploit this map in communication system design.Read moreRead less
Opening a New Era of High-Performance Microwave Devices. We propose a conceptually new method of manufacturing high-performance microwave components at the low-cost and short lead time using liquid form conductors and 3D printing technology. Innovation consists in developing surface roughness free waveguide- and coaxial-based RF and microwave devices, in one-single-piece. This technique can be further extended to create high-performance reconfigurable RF and microwave devices such as filters, an ....Opening a New Era of High-Performance Microwave Devices. We propose a conceptually new method of manufacturing high-performance microwave components at the low-cost and short lead time using liquid form conductors and 3D printing technology. Innovation consists in developing surface roughness free waveguide- and coaxial-based RF and microwave devices, in one-single-piece. This technique can be further extended to create high-performance reconfigurable RF and microwave devices such as filters, antennas, directional couplers, phase shifters and switches by manipulating the locations of the liquid conductors. Furthermore, the method will enable the management of heat generated in high-power applications. Australian telecommunication industry and defence will benefit from the outcome of this project.Read moreRead less
Reconfigurable Conformal Antenna Arrays for Broadband in the Sky Networks. The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas. The antenna would be conformal to the surface of the mounting platform, and its elements would be reconfigured in situ to generate the optimum rad ....Reconfigurable Conformal Antenna Arrays for Broadband in the Sky Networks. The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas. The antenna would be conformal to the surface of the mounting platform, and its elements would be reconfigured in situ to generate the optimum radiation characteristics to suit the radio environment. It is expected that the project would advance the scientific knowledge of space-borne wireless communications and sensing in general, and antennas in particular, and significantly enhance the performance and reduce the cost of BISNets.Read moreRead less
