Personal profile
Artistic and research interests
My main research topics are sub-6 GHz antennas for mobile devices, and millimeter-wave beam-steerable antennas for mobile devices, mobile networks and radars. Regarding sub-6 GHz antennas, I aim at finding solutions that would provide significantly higher efficiency than the currently used antennas. At millimeter waves, I aim at finding feasible beam-steerable antenna solutions for mobile devices and wide-band antennas whose beam is steerable across a very broad angular range in networks and radars. Besides, I develop wireless sensors powered only with ambient RF energy.
