Hybrid-resonator antennas for wireless communication networks. The rapid emergence of modern wireless communication systems has led to a requirement for small, lightweight antennas. In this project, a new, broadband, low-cost, small and lightweight antenna architecture will be developed for wireless systems.

The rapid emergence of modern wireless communication systems has led to a requirement for small, lightweight antennas. In this project, a new, broadband, low-cost, small and lightweight antenna architecture will be developed for wireless systems. The new architecture is based on a novel hybrid-resonator concept: a dielectric resonator tightly coupled to a metal patch resonator. The rapid design and optimisation of new antennas will be achieved by developing several new theoretical methods. Antennas targeted for the Unlicensed National Information Infrastructure (UNII) band (5-6 GHz) commercial wireless communication systems will be designed, fabricated, tested and integrated with the systems.

Numerically Robust Extruder Die Design for Fabricating High-Quality Preforms for Microstructured Polymer Optical Fibres. Microstructural polymer optical fibres (mPOFs) were pioneered in Australia, are now comparable in performance (but much more versatile) than conventional polymer fibre, and are a highly attractive commercial option. Potential industrial applications envisage cost-effective preform fabrication as a key issue, with extrusion as the favoured route. This interdisciplinary project ....Numerically Robust Extruder Die Design for Fabricating High-Quality Preforms for Microstructured Polymer Optical Fibres. Microstructural polymer optical fibres (mPOFs) were pioneered in Australia, are now comparable in performance (but much more versatile) than conventional polymer fibre, and are a highly attractive commercial option. Potential industrial applications envisage cost-effective preform fabrication as a key issue, with extrusion as the favoured route. This interdisciplinary project benefits Australia by (i) extending and exploiting our research advantages in advanced photonics and computational rheology, (ii) providing the 'missing link' for large-scale mPOF production and positioning us to reap the economic benefits of this innovative technology, and (iii) providing computational techniques for rheological modelling that are applicable in diverse Australian industry sectors.Read moreRead less

The revenue generated from traditional telecommunication services is continuing to drop. New value-added services such as multimedia services become the fastest growing revenue-generating sector in Australia's telecommunications industry. The ubiquitous presence of scaling behaviour in network traffic presents a big challenge for delivering better Quality-of-Service (QoS) which is demanded by the new services. A complete understanding of the scaling behaviour and its impact is very important. This research addresses a key problem of defining the timescale range of interest for the scaling behaviour. The research outcome benefits a number of areas, which are all critical for developing enhanced QoS support and better network management.Read moreRead less
