COUPLING ENHANCEMENT INTERMEDIARY COIL FOR TAG COMMUNICATION STANDARDIZATION

摘要

Systems include a transceiver having a transceiver antenna, a transponder positioned a first distance from the transceiver, and an intermediate structure positioned a second distance from the transponder (where the first distance is greater than the second distance). The transponder has a transponder antenna, and the intermediate structure has an intermediate antenna (and a capacitor). The transponder antenna is a first size antenna (smallest), the intermediate antenna is a second size antenna (bigger), and the transceiver antenna is a third size antenna (biggest). The intermediate structure provides field lines between the transceiver antenna and the transponder antenna that the transponder antenna is otherwise incapable of fully receiving from the transceiver antenna. This causes the intermediate antenna to transfer voltage received from the transceiver antenna to the transponder antenna.
