AI Technical Summary

Benefits of technology

The conductive layer effectively shields unwanted signals, reduces interference, and enhances the reliability and directionality of wireless communications, improving the performance of the communication device even when attached to metal objects.

Problems solved by technology

Such identification systems configured to communicate via radio frequency signals are susceptible to incident RF radiation.
Such RF radiation can degrade the performance of the identification system.
For example, application of transponders to objects comprising metal may result in decreased or no performance depending on the spacing of the transponder antenna to the nearest metal on the object.

Abstract

The present invention relates to wireless communication devices and methods of forming and operating the same. The present invention provides a wireless communication device including a substrate having a support surface, wireless communication circuitry upon the support surface of the substrate, at least one antenna electrically coupled with the wireless communication circuitry, a conductive layer configured to interact with the antenna, and an insulative layer intermediate the conductive layer and the antenna. A method of forming a wireless communication device includes providing a substrate having a support surface, forming an antenna upon the support surface, conductively coupling wireless communication circuitry with the antenna, forming an insulative layer over at least a portion of the antenna, and providing a conductive layer over at least a portion of the insulative layer.

Description

TECHNICAL FIELD [0001] The present invention relates to wireless communication devices and methods of forming and operating the same. BACKGROUND OF THE INVENTION [0002] Electronic identification systems typically comprise two devices which are configured to communicate with one another. Preferred configurations of the electronic identification systems are operable to provide such communications via a wireless medium. [0003] One such configuration is described in U.S. patent application Ser. No. 08 / 705,043, filed Aug. 29, 1996, assigned to the assignee of the present application and incorporated herein by reference. This application discloses the use of a radio frequency (RF) communication system including communication devices. The communication devices include interrogator and a transponder such as a tag or card. [0004] The communication system can be used in various identification and other applications. The interrogator is configured to output a polling signal which may comprise ...
