Abstract
A method of detecting products includes a magnetic field generating device configured to generate a magnetic field, and a split ring resonator assembly configured to be magnetically coupled to the magnetic field generating device and configured to focus the magnetic field produced by the magnetic field generating device.
Claims11
An RFID antenna assembly configured to be energized with a carrier signal, the RFID antenna assembly comprising:
- an inductive component including a multi-segment loop antenna assembly, wherein the multi-segment loop antenna assembly includes:
- at least a first antenna segment including at least a first phase shift element configured to reduce the phase shift of the carrier signal within the at least a first antenna segment;
- at least a second antenna segment including at least a second phase shift element configured to reduce the phase shift of the carrier signal within the at least a second antenna segment;
- at least one far field antenna assembly;
- and
- at least one matching component configured to adjust the impedance of the multi-segment loop antenna assembly,
- wherein the length of each antenna segment is no more than 25% of the wavelength of the carrier signal.
