Microwave System for Early Breast Cancer Detection Employing Ultra Wideband Conformal Array Antenna. Breast cancer is the most common cancer diagnosed in women in various parts of the world. Currently the primary method for breast screening is X-ray mammography and in rare cases Magnetic Resonance Imaging. X-ray mammography has saved many lives, but the technology still produces a relativity high number of false negative and false positive diagnoses. In the last decade, active microwave techniqu ....Microwave System for Early Breast Cancer Detection Employing Ultra Wideband Conformal Array Antenna. Breast cancer is the most common cancer diagnosed in women in various parts of the world. Currently the primary method for breast screening is X-ray mammography and in rare cases Magnetic Resonance Imaging. X-ray mammography has saved many lives, but the technology still produces a relativity high number of false negative and false positive diagnoses. In the last decade, active microwave techniques have attracted considerable interest as viable alternatives to X-ray mammography. This project aims at the design and development of a low-cost microwave system, which will complement all the currently available breast cancer diagnosis tools. Read moreRead less
Radio Frequency Wireless Monitoring in Sleep Apnoea (Particularly for Paediatric Patients). Disease diagnosis, chronic disease monitoring and stress monitoring all are limited by diagnostic systems that are attached to patients by wires restricting the recording of such parameters to limited intervals in the clinician's office. The proposed system will enable patients to have a range of physiological parameters recorded without the attachment of wires. This will enable extensive periods of dia ....Radio Frequency Wireless Monitoring in Sleep Apnoea (Particularly for Paediatric Patients). Disease diagnosis, chronic disease monitoring and stress monitoring all are limited by diagnostic systems that are attached to patients by wires restricting the recording of such parameters to limited intervals in the clinician's office. The proposed system will enable patients to have a range of physiological parameters recorded without the attachment of wires. This will enable extensive periods of diagnostic data to be recorded to characterize respiratory, cardiac and other parameters during extended periods, and during normal daily activity. In addition the system can be used to monitor patients with chronic disease and detect trends in their disease.Read moreRead less
Printable Multi-Bit Radio Frequency Identification for Banknotes. This project will investigate inexpensive radio-frequency transponders on banknotes that enjoy all of the advantages of, and, indeed, operate in a manner somewhat similar to barcodes. Transponders of this type may potentially replace barcode technology, thereby allowing automated identification of individual banknotes at multiple points in transaction chains. The resulting efficiencies in banknote authentication and other applic ....Printable Multi-Bit Radio Frequency Identification for Banknotes.

Transponders of this type may potentially replace barcode technology, thereby allowing automated identification of individual banknotes at multiple points in transaction chains. The resulting efficiencies in banknote authentication and other applications will generate a significant economic benefit for Australia. Additionally, the development of state-of-the-art transponders based on fundamental microwave- and antenna engineering prospectively gives Australia a cutting-edge advantage as a leading player in the fast-growing RFID market.Read moreRead less

Microwave Differential Imaging of Myocardium for Assessment and Therapeutic Monitoring of Transcatheter Cardiac Ablation. We propose to develop Microwave Imaging techniques for cardiovascular disease diagnosis at 2.45 GHz. Firstly, we aim to image the contrast in the complex dielectric constants of healthy and ischaemic heart tissue. The second aim is to image the extent and efficacy of therapeutic lesion formation due to cardiac ablation modalities.

Smart Antennas for Broadband Wireless Data Systems. Smart antennas can facilitate accommodation of an increasing demand for bandwidth and quality in wireless communications by directing the antenna beam towards the desired user, while suppressing signals coming from interferers. The beam forming processor can adapt to changes in channel propagation conditions as well as movements of the user or interferers. Many algorithms for controlling smart antennas have been proposed, and usually there is a ....Smart Antennas for Broadband Wireless Data Systems. Smart antennas can facilitate accommodation of an increasing demand for bandwidth and quality in wireless communications by directing the antenna beam towards the desired user, while suppressing signals coming from interferers. The beam forming processor can adapt to changes in channel propagation conditions as well as movements of the user or interferers. Many algorithms for controlling smart antennas have been proposed, and usually there is a trade-off between complexity and performance. We aim to find a suitable compromise to implement smart antennas for broadband wireless access systems and to apply smart antenna technology to increase the range of ultra-wideband communications.Read moreRead less
