A rapidly growing demand for fast wireless services calls for wideband communication systems with wideband antennas, which are compact, aesthetically appealing and inexpensive, yet have good performance. With novel concepts, this project aims to produce a new class of antennas that deliver impressive performance (bandwidth and gain) while taking up a dramatically reduced area in a way that was impossible before, increasing a figure-of-merit to up to seven times the state-of-the-art. Their planar geometry and simplicity lead to low cost. This is expected to create new knowledge, design methods and examples, prototypes, test results and guidelines required to design, optimise and make these versatile antennas for emerging robust broadband wireless systems.Read moreRead less
Dual-band antennas with digitally steerable beams made out of multi-state electromagnetic elements. A collection of antennas required for forthcoming wireless systems will be designed, made and tested. They are ideal for wireless on-body medical devices and wireless transmission of high-quality video and high-speed data. These systems will bring great benefits to wireless users and patients, including better quality of life and convenience.

Summary
Integration of Nanoantenna-Enhanced Sensors and Light Sources. Metal nanoparticles are ideal candidates to enhance and modify the radiation of nanoscale light sources. However, research in nano light sources is only just beginning, thus their full potential has not yet been unlocked. This project aims to develop novel nano light sources to control the polarisation-state of emission and to enhance their efficiency and brightness. The project aims to deliver a new technology platform for on-chip i ....Integration of Nanoantenna-Enhanced Sensors and Light Sources. Metal nanoparticles are ideal candidates to enhance and modify the radiation of nanoscale light sources. However, research in nano light sources is only just beginning, thus their full potential has not yet been unlocked. This project aims to develop novel nano light sources to control the polarisation-state of emission and to enhance their efficiency and brightness. The project aims to deliver a new technology platform for on-chip integration of these light sources which is needed to demonstrate real-world applications. This platform will also be used to develop a new class of compact waveguide sensors that are highly sensitive and flexible with a broad range of applications.Read moreRead less
New Technologies for Second Generation Search and Rescue. This project aims to improve the Cospas-Sarsat search and rescue system to ensure faster, more reliable, more accurate, and more cost-effective search and rescue operations, ultimately saving lives. The satellite-based Cospas-Sarsat system has assisted with the emergency rescue of more than 35 000 lives worldwide since its introduction in 1982.

This project aims to improve the Cospas-Sarsat search and rescue system to ensure faster, more reliable, more accurate, and more cost-effective search and rescue operations, ultimately saving lives. The satellite-based Cospas-Sarsat system has assisted with the emergency rescue of more than 35 000 lives worldwide since its introduction in 1982. A second generation of this system is currently under development, promising to significantly improve detection rate and localisation accuracy. However, in an emergency, the system’s performance is often compromised due to interference and atmospheric effects, leading to false detections that waste valuable resources. This project aims to develop novel techniques to improve this performance.Read moreRead less

Signal Processing for Reconfigurable Antennas – a Multidisciplinary Approach for Next Generation Wireless Communications. To satisfy the enormous demand for wireless applications with scarce radio spectrum, new technologies must be researched, developed, and then employed. Reconfigurable antennas, through morphing their physical structures with various switches, can adapt to the radio propagation environment, thereby increasing spectrum efficiency and power efficiency of wireless communications. ....Signal Processing for Reconfigurable Antennas – a Multidisciplinary Approach for Next Generation Wireless Communications.

This project aims to demonstrate room temperature hybrid nanowire-nanoantenna infrared photodetectors by integrating plasmonic nanoantennas on semiconductor nanowire arrays. It is expected that such novel device architectures will not only bring enhanced performance in responsivity, detectivity, and photoresponse bandwidth, but also additional functionalities such as selective wavelength and tunable polarisation, which may significantly outperform current infrared technology.
