Patent ID: 8330298

Claim:
A method of converting RF energy from ambient electro-magnetic (EM) radiation into useable electric power using a simultaneous collector of ambient radio frequencies (SCARF) circuit, the method comprising: simultaneously capturing EM radiation from a plurality of ambient RF or microwave signals using an array of antennae having at least two antennae, each signal having a different resonant frequency; aggregating the plurality of ambient signals to generate an aggregated signal having a single predetermined intermediate frequency signal with greater AC power than AC power of each of the plurality of ambient signals individually, wherein the single predetermined intermediate frequency is either a sum of the resonant frequencies of the plurality of ambient signals or a difference between the resonant frequencies of the plurality of ambient signals; and converting the aggregated signal into useable electric power using a rectifying circuit, wherein for every incremental increase in the AC power of the aggregated signal, there is a corresponding exponential increase in DC power at the output of the rectifying circuit.
