An encoding module and related systems and components are provided. The encoding module includes a plurality of encoding elements arranged in an array of columns and rows and one or more switching elements configured to selectively connect the encoding elements to a reader. The connection of the encoding elements may be based on the location of a targeted transponder disposed among multiple adjacent transponders to ensure the selective communication with the targeted transponder only. The module is configured for various types and locations transponders to be used within a system, such as a printer-encoder. Each encoding element may include a loaded conductive strip comprising a loop shape portion and a shield that corresponds to the loop shape portion. In another embodiment, an access control system having an encoding module with the plurality of couplers and an access card having a plurality of transponders corresponding to the couplers is provided.

Encoding module, associated encoding element, connector, printer-encoder and access control system

A RFID system and an associated antenna-coupler are provided. The system may be for selectively communicating with a targeted transponder from among a group of multiple adjacent transponders is provided. The system may include a transponder conveyance, a transceiver, and an antenna-coupler. The transponder conveyance is adapted to transport at least one targeted transponder from a group of multiple adjacent transponders through a transponder operating region. The transceiver is configured to generate one or more electrical signals. The antenna-coupler has first and second microstrips in a cross-like arrangement relative to each other. Each of the first and second microstrips is configured to transmit one or more electro-magnetic fields concentrated in a near-field region of the antenna-coupler based on the one or more electrical signals for communicating with the targeted transponder.

RFID system and associated antenna-coupler

An example media processing device includes a coupler configured to transmit wireless signals to an encoding area, the coupler to transmit the wireless signals via a plurality of radiating elements; a controller to control which set of the radiating elements is to transmit the wireless signals; and a processor to adapt the coupler to a transponder configuration by: encoding a first transponder of the transponder configuration using the first set of the radiating elements to transmit the wireless signals; executing a first encoding evaluation on the encoded first transponder; encoding a second transponder of the transponder configuration using the second set of the radiating elements to transmit the wireless signals; executing a second encoding evaluation on the encoded second transponder; and selecting, based on the first and second encoding evaluations, the first set or the second set as a preferred radiating set for the transponder configuration.

Near field coupling devices and associated systems and methods

A near-field coupling device that may facilitate communications with a transponder is provided. The near-field coupling device may include a ground plane, a dielectric substrate, one or more conductive strips and a terminating load. The conductive strips together with the ground planes form coupling elements. The near-field coupling device further includes one or more switching elements for selectively connecting and disconnecting the coupling elements with a transceiver. The connected coupling elements define a total characteristic impedance. Using the switching element, the ratio between the total characteristic impedance of the connected coupling elements and the terminating load may be changed in order to adjust the distribution of an electromagnetic field along the coupling elements according to the type and position of the transponder to be processed.
