Jani Ollikainen

Research Leader
Espoo, Finland

I received my D.Sc. (Tech.) degree from the Helsinki University of Technology (TKK), Espoo, Finland, in 2004. The title of my doctoral thesis was "Design and Implementation Techniques of Wideband Mobile Communications Antennas". From 1996 to 2003, I was with the Radio Laboratory of TKK researching small internal antennas for mobile phones. In early 2003, I joined Nokia Research Center (NRC) in Helsinki, where I continued small antenna research as a Senior Research Engineer. From 2005 to 2008, I worked at NRC leading research teams and projects in the areas of antennas and electromagnetics. Since the beginning of 2009, I have led the Enabling Radio Technologies research team. My main research interests include small antennas for personal mobile communications and cognitive radio.
