Patent ID: 8022815

Claim:
An RFID magnetic coupler arrangement, comprising: an input signal source that provides an input signal having a target wavelength; a splitter including a single conductive transmission line coupled to the signal source that receives the input signal and splits the input signal into a first signal and a second signal, said splitter being configured to phase-shift said second signal by 180 degrees; a dielectric substrate having a longitudinal axis extending along a length thereof; a first elongated conductive patch that receives the first signal and is disposed over a first surface of the substrate; and a second elongated conductive patch that receives the second phase-shifted signal and is disposed over the first surface of the substrate opposite and spaced from the first conductive patch, wherein the first conductive patch and the second conductive patch are longitudinally aligned with one another and extend along the longitudinal axis of the dielectric substrate, the input signal source being disposed on a second surface of the substrate, the second surface of the substrate being on a vertically opposed side of the dielectric substrate to a side of the dielectric substrate defining the first surface of the substrate.
