Abstract

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.

First claim

That which is claimed:

1 . An encoding element comprising:
a ground plane; a first dielectric substrate adjacent to the ground plane; a conductive strip adjacent the first dielectric substrate and extending from an input end to a loaded end and comprising at least one portion having a loop shape; a terminating load in communication with the loaded end of the conductive strip a second dielectric substrate adjacent the conductive strip; and a shield adjacent an opposite surface of the second dielectric substrate from the conductive strip and generally corresponding to the at least one portion having a loop shape of the conductive strip including providing a central open area.
