1. An apparatus, comprising:
- means for receiving RF radiation within a plurality of frequency bands; and
means for converting separately the received RF radiation associated with each of the plurality of frequency bands into DC, the converting means includes an inductor and at least three taps, each tap from the at least three taps being placed at a unique point along the inductor to access an energy associated with the RF radiation.

Abstract
An apparatus for a wireless power supply including a mechanism for receiving a range of RF radiation across a collection of frequencies. The apparatus includes a mechanism for converting the RF radiation across the collection of frequencies, preferably at a same time into DC. A method for a wireless power supply including the steps of receiving a range of RF radiation across a collection of frequencies. There is the step of converting the RF radiation across the collection of frequencies, preferably at a same time into DC.

18. An apparatus, comprising:
-
means for receiving a range of RF radiation across a collection of frequencies with a single antenna; and means for converting RF radiation across the collection of frequencies from the single antenna into DC, the converting means includes an inductor that is resonant for a desired band of RF spectrum, the inductor having a plurality of taps placed at points along the inductor to access the RE energy.

19. A method, comprising:
-
receiving a range of RF radiation across a collection of frequencies at a single antenna; converting the RF radiation received at the single antenna across the collection of frequencies into DC by absorbing the energy with an inductor; and accessing the absorbed energy with a plurality of taps on the inductor.

20. A method, comprising:
-
receiving radiation within an RF spectrum band via a single antenna, a first portion of the received radiation being associated with a first portion of the RF spectrum band, a second portion of the received radiation being associated with a second portion of the RF spectrum band different than the first portion; converting separately the received radiation from each of the first portion of the RF spectrum band and the second portion of the RF spectrum band into a DC voltage; and combining the DC voltage associated with the first portion of the RF spectrum band and the DC voltage associated with the second portion of the RE spectrum band.
