Assignee:

Sensormatic Electronics, LLC - Boca Raton FL

International Classification:

H01Q 1/32

US Classification:

343700MS

Abstract:

A near field antenna is disclosed which is configured to read an RFID label such that a localized electric E field emitted by the antenna at an operating wavelength resides substantially within a zone defined by the near field. The localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.

Richard L. Copeland - Lake Worth FL, US

International Classification:

G08B 13/14

US Classification:

3405727

Abstract:

A method and an analogous system for tuning an RFID label prior to application to an article are disclosed. The method includes providing an RFID label having at least one antenna disposed therein, identifying an article, relaying information related to the identification of the article to a controller, with the controller including a memory of predetermined tuning parameters for the article, retrieving from memory one or more of the tuning parameters for the article; and adjusting the tuning parameters of the RFID label to correspond to the article by altering a geometric parameter of the antenna of the RFID label. The system includes a cutting device to alter a geometric parameter to correspond to the article by removing material from at least one antenna forming part of the RFID label.
