1. An autonomous battery-free microwave frequency communication device, comprising:

  • a capacitance;

    at least one antenna;

    a microwave energy harvesting system which is configured to harvest and store microwave energy received via said at least one antenna onto said capacitance;

    a microwave frequency transceiver empowered by energy stored on said capacitance, which is configured to use a portion of energy stored on said capacitance to autonomously generate a microwave frequency carrier and to autonomously transmit information using said microwave frequency carrier according to a predetermined communications protocol via said at least one antenna; and

    a control system empowered by energy stored on said capacitance, which is configured to provide said information for transmission.
