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.

Electromagnetic field strength simulator (ELMO) for RF hazard assessment. There is significant community fear related to exposure to mobile telephone radiation. The computer program ELMO will be designed to accept information about all RF transmitters in the vicinity of cellular telephone towers from an existing database, and to calculate the total field strength. This will allow hazard assessment for both RF technicians working on the tower and adjacent residents.

The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.Read moreRead less

Recently, the capacity of the broadcast channel with multiple antennas is investigated. Various space-time (ST) processing techniques to adapt channel conditions are utilized to increase capacity. Precoding becomes vital to deal with interferers and cooperation problems efficiently. ST codes will be investigated in conjunction with precoding. We aim to investigate channel adaptive ST coding and precoding techniques to achieve the maximum capacity with practical quality of service requirements. Although the capacity is extensively investigated, implementation methods are relatively less investigated. This project is to fill the cap between implementation (ST coding and precoding methods as outcomes) and theory (capacity analysis).Read moreRead less
