Unprecedented emergence of new wireless applications in recent years pervades all aspect of our life. To host all these applications and accommodate the future ones in a single platform, flexible multi-purpose wireless devices are required. These devices need to sense environmental conditions, adapt to user requirements, and decide how to communicate among themselves in a self-organized manner. Achieving such versatility and performance with current state-of-the-art technology is extremely difficult if not impossible. It involves bulky, complex and expensive system which are not amenable to the high level of miniaturizations and integrations imposed by many of these applications. These challenges highlight the need for a conceptual approach to redefine the way that these wireless devices interact with outside environments. Our proposed solution to address these challenges is to transfer the implementation of these main features i.e. “sensing, intelligence and adaptability” from higher physical layers to the level of antenna apertures and investigate new topology in which systems become the integral part of antenna structures. This approach enables antennas to act as multifunctional systems with unparalleled level of integration that can be conform to the body of a car, human or plane and offers unmatched levels of performance.
Currently my research group is concentrating in four research themes:
- Intelligent ultra-wideband sensor
- Intelligent sensor-antennas for cognitive wireless sensor networks
- Intelligent multifunctional antennas
- Intelligent integrated sensor- antenna structures based on 3-D printing technologies.
