Abstract

See full text

Pathogens (e.g., viruses or bacteria) within a volume of air can be killed or deactivated using RF energy. A plurality of phase shifters input an RF signal and output a phase-shifted version of the RF signal at their respective outputs, wherein an amount of phase shift introduced by each of the phase shifters is controllable. A phased array antenna has a plurality of microwave radiators, and each of the respective outputs of the phase shifters drives a respective one of the microwave radiators. A controller controls the phase shifters to drive the phased array antenna such that a beam of RF energy emanates from the phased array antenna and sweeps through a volume positioned in front of the phased array antenna, and the beam of RF energy kills or deactivates the pathogens.
