Abstract

This paper summarizes our recent advances in antenna designs for ultra wideband (UWB) applications. Two types of monopoles are studied and developed in our research group. The first type belongs to the electric monopole with a circular disc fed by three different feeding structures. The second type is the magnetic monopole with an elliptical slot. The performances of these two types of antennas are evaluated in both frequency and time domains. The important design parameters for achieving optimal operations are also analyzed. It is shown that both electric and magnetic monopoles can provide ultra wide bandwidth with nearly omni-directional radiation patterns over the entire frequency band. In addition, the impulse responses of the selected antennas are shown to correspond well to the frequency domain characteristics.

Xiaodong Chen (M’96) received the degree of B.Sc. in Electronic Engineering from the University of Zhejiang, Hangzhou, China in 1983, and the degree of Ph.D. in microwave electronics from the University of Electronic Science and Technology of China, Chengdu in 1988. In September 1988 he joined the Department of Electronic Engineering at King's College, University of London, as a Postdoctoral Visiting Fellow. In September 1990 he was employed by the King’s College London as a Research Associate. In March 1996 he was appointed to an EEV Lectureship at King's College London. In September 1999 he joined the Department of Electronic Engineering at Queen Mary and Westfield College, University of London as a College Lecturer. In October 2003, he was promoted to a Readership at the same institution. His interests are in microwave devices and antennas, bio-electromagnetic and nonlinear dynamics and chaos. He has authored and co-authored over 130 publications (book chapters, journal papers and refereed conference presentations). He has involved in the organisation of many international conferences; he has served as Chairman of Institute of Electrical Engineers (IEE) International Workshop on Ultra Wide Band Technologies and Systems (2004), co-chairman of the Institute of Physics (IoP) / IEE International Workshop on RF Interaction with Humans (2003), Executive Chairman of ‘The International Conference on Telecommunications (ICT), 2002’. He is currently a member of UK EPSRC Review College and Technical Panel of IEE Antennas and Propagation Professional Network.
