Abstract
A system for conveying a radio frequency (RF) signal from a base station to a detached integrated circuit (IC) has an intermediate resonant circuit and an IC. The intermediate resonant circuit is configured to resonate in response to the RF signal from the base station, reproducing the RF signal. The IC has an integral resonant circuit configured to resonate in response to the reproduced RF signal. The IC and the intermediate resonant circuit are affixed proximate each other. Both are separate from the base station and each other. Either or both of the intermediate resonant circuit and the integral resonant circuit may contact a high magnetic permeability layer. The intermediate resonant circuit may be formed of conductive ink.
