Backscattering Different Radio Frequency Protocols
First Claim
1. A Radio Frequency (RF) tag, comprising:
- an antenna configured to receive an RF signal from any of a plurality of readers, wherein each reader is associated with a different protocol having different time durations; and
a storage module coupled to the antenna and configured to store energy associated with the RF signal and substantially maintain a voltage in the tag during any of the different time durations independent of an internal power supply.

Abstract
The present disclosure is directed to a system and method for backscattering different radio frequency protocols. In some implementations, a radio Frequency (RF) tag includes an antenna and a storage module. The antenna is configured to receive an RF signal from any of a plurality of readers. Each reader is associated with a different protocol having different time durations. The storage module is coupled to the antenna and configured to store energy associated with the RF signal. In addition, the storage module substantially maintains a voltage in the tag during any of the different time durations independent of an internal power supply.
