The rapid development of wireless communications and the emerging demand for high frequency, high efficiency microwave devices and systems for sensing applications have prompted considerable interest in antenna technology such as the realisation of small size (without comprising gain), wide bandwidth and linear phase response devices. This project aims to develop and study MEMS enabled high gain (and reconfigurable) antennas for RF and microwave applications. Microstrip based stacked patch antennas have been designed and fabricated successfully. Some of the targeted applications are ultra wide band wireless communications, on chip communications, collision avoidance radar at 76 GHz and millimetre sensors. Electromagnetic simulation and measurement have shown the devices provide enhanced performance compared to the conventional devices. Further work is being carried out to obtain compact and high efficiency devices.
