Research summary

My research is broadly in the area of RF and microwave electronics, in which I have built up expertise  since 1984. Particular areas are as follows:

RF circuits and systems. Particularly phase-locked loops and PLL frequency synthesisers. RFID tags. Antennas, phased arrays. Location systems.

Radar systems, especially for geophysical imaging applications, such as snow avalanche imaging and Antarctic ice shelf imaging. Active target location radar for marine navigation. RF-based medical imaging. Many of my ideas have resulted in patents.

Paul Brennan was born in London, UK, in 1963 and obtained a BSc(Eng) degree in 1984 and a PhD degree in 1988 in Electronic and Electrical Engineering from University College London (UCL).

After a short spell working on agile transceivers for Plessey Military Communications, he rejoined UCL as a PhD student and then Research Fellow and is now a Professor of Microwave Electronics. He has published widely in many areas, including radio frequency and microwave electronics, antennas, radar and phase-locked loops, including a textbook on the subject 'Phase-locked loops, principles and practice' (McGraw-Hill/Macmillan, 1996). His current research interests include MIMO / phased array radar imaging systems for geophysical applications, such as snow avalanches and Antarctic ice shelves, radar location systems, phased array and other antenna systems, phase-locked loops and general RF/microwave electronics.

Prof. Brennan is highly active as a consultant and is a member of the Rolls Royce Electrical, Control Systems and Electronics Advisory Board. He is a Fellow if the Institute of Engineering and Technology, Deputy Head of the Electronic & Electrical Engineering Department at UCL and Head of the Sensors, Systems and Circuits research group.
