Research & Innovations
Recent breakthroughs in wireless power transfer (WPT) systems have achieved high RF-to-DC conversion efficiencies—up to 94%—using advanced rectifier designs and CMOS modeling. Innovations in UWB phased arrays, Vivaldi antennas, and reflectarrays enable dynamic beam steering and efficient energy delivery, with some systems reaching over 87% beam collection. High-performance GaN and CMOS power amplifiers further enhance far-field power beaming for mobile and aerial applications. Explore our research findings here.
