Wireless communications systems

The microwave wireless systems group is also part of the London Metropolitan University Microwaves (LMUM), which was one of the original and principal research groups within the School of Computing and Digital Media. Radio and microwave systems are at the core of the wireless communications revolution and play a key role in mobile phones, satellite broadcasting, navigation radar and remote sensing. Hence, research in this area focuses on developing enabling technologies to meet the challenging demands for the next generation of wireless communications systems, eg 3G, Bluetooth, WLAN, RFID, satellite communications, GPS navigation and future cellular communication systems.

Specific research activities include:

reconfigurable devices
techniques to suppress spurii in devices such as filters for electromagnetic compatible (EMC) systems
photonic band-gap (PBG) miniature devices
novel microstrip resonators for frequency selective applications using fractal
efficient high-power RF amplifiers
ultra-broadband amplifiers
ultra-low noise tuneable reference oscillators with low phase noise
broad tuning low noise voltage controlled oscillators (VCO)
efficient low-noise oscillators
linear broadband highly efficient power amplifiers
multimode filters
ultra-broadband frequency discriminating devices
metamaterial filters for wireless communications systems
novel narrowband microstrip filters for wireless communication
development of a new security mechanism reference and model for intrusion detection systems in wireless LANs

All work in the microwave area is supported by fully integrated laboratories, including: Electronic Design Automation (EDA) software from Agilent Technologies USA, such as Advance Design System (ADS?) for high-frequency system, circuit, and modelling applications; thick-film manufacturing; and modern test instrumentation. ADS? is an industry standard state-of-the-art EDA software system. These facilities are intensively utilized for both research and teaching purposes.
