Abstract
A system and method for sterilizing recirculated airflow in closed environments, as well as certain types of material equipment includes electronically steered antenna (ESA) elements. The ESA elements operate in radio frequencies (RF). The ESA elements produce directed beams of microwave radiation to sterilize surfaces or volumes of air. The directivity gain associated with the beam forming increases RF energy density in the area where the beam is steered.
Claims5
A method for sterilizing an enclosed volume comprising:
- defining the enclosed volume with a plurality of electronically steered array antenna panels and radio opaque parabolic reflector endcaps;
- determining one or more frequency ranges for the plurality of electronically steered array antenna panels based on characteristics of a target pathogen;
- applying signals to each of the plurality of electronically steered array antenna panels to produce steerable beams in the one or more frequency ranges;
- and
- reflecting sidelobes produced by the plurality of electronically steered array antenna panels within the enclosed volume,
- wherein the radio opaque parabolic reflector endcaps define doors into the enclosed volume.
