Antennas for Portable Devices

Zhi Ning Chen is Lead Scientist, Head for Antenna Lab and Manager for Radio Systems Department, Institute for Infocomm Research, Singapore.? Zhi Ning has been working on applied electromagnetics, antennas and RF systems for 20 years. Recently, his major research interests include wave propagation, antennas, and RF design for UWB-(Ultra WideBand) and MIMO- (multiple input, multiple output) based radio systems. He has conducted research work on UWB, including the study of small and broadband antennas for UWB radio systems, measurements on pulsed antennas UWB, assessment of diversity performance of multiple antennas in UWB systems, effects of the human body on the UWB signal propagation, co-design of antennas and RF circuits for UWB transceivers. He has been invited to give talks on UWB antenna design and measurement at several international conferences and workshops, and has organized many international UWB events
