Abstract

An RFID system includes an RFID antenna assembly configured to be positioned on a product module assembly of a processing system. The product module assembly is configured to releasably engage at least one product container. A first RFID tag assembly configured to be positioned on the at least one product container. The at least one product container is configured to position the first RFID tag assembly within a detection zone of the RFID antenna assembly whenever the product module assembly releasably engages the at least one product container.

First claim

What is claimed is:

1 . A method for loading products into a processing system, comprising:
providing a housing assembly including at least one secured access door, the access door including an RFID antenna assembly having inductive component formed as a multi-segment loop antenna assembly configured to be energized with a carrier signal; providing a plurality of product containers, each having an inductive component unique to a product therein; positioning one of said product containers proximate said at least one secured access door; receiving a signal from said inductive component to allow RFID-based actuation of the processing system if the appropriate inductive component is positioned proximate the RFID antenna assembly; and opening said at least one secured access door if said RFID-based actuation is engaged.

2 . The method of claim 1 , wherein the RFID antenna assembly is configured to be coupled with an RFID subsystem that is capable of generating the carrier signal.

3 . The method of claim 2 , wherein the carrier signal is a 915 MHz carrier signal.

4 . The method of claim 1 , wherein the multi-segment loop antenna assembly comprising at least a first antenna segment including at least a first phase shift element configured to reduce the phase shift of the carrier signal within the at least a first antenna segment.

5 . The method of claim 4 , wherein the multi-segment loop antenna further comprising at least a second antenna segment including at least a second phase shift element configured to reduce the phase shift of the carrier signal within the at least a second antenna segment.

6 . The method of claim 5 , wherein the length of each antenna segment is no more than 25% of the wavelength of the carrier signal.

7 . The method of claim 6 , wherein at least one matching component configured to adjust the impedance of the multi-segment loop antenna assembly.

8 . The method of claim 1 , wherein the wavelength of the carrier signal is approximately thirteen inches.

9 . The method of claim 1 , wherein the inductive component includes:
at least one far field antenna assembly.

10 . The method of claim 9 , wherein the far field antenna assembly is a dipole antenna assembly.

11 . The method of claim 9 , wherein the far field antenna assembly includes a first antenna portion and a second antenna portion.

12 . The method of claim 11 , wherein the sum length of the first antenna portion and the second antenna portion is greater than 25% of the wavelength of the carrier signal.

13 . A method for loading products into a processing system, comprising:
providing a housing assembly including a plurality of secured access doors configured to receive a specified product, each of said access doors including an RFID antenna assembly having inductive component formed as a multi-segment loop antenna assembly configured to be energized with a carrier signal; providing a plurality of product containers, each having an inductive component unique to a product therein; positioning one of said product containers proximate one of said secured access doors; receiving a signal from said inductive component to allow RFID-based actuation of the processing system if the appropriate inductive component is positioned proximate the RFID antenna assembly; and opening said proximate secured access door if said RFID-based actuation is engaged.

14 . The method of claim 13 , wherein the RFID antenna assembly is configured to be coupled with an RFID subsystem that is capable of generating the carrier signal.

15 . The method of claim 14 , wherein the carrier signal is a 915 MHz carrier signal.

16 . The method of claim 13 , wherein the multi-segment loop antenna assembly comprising at least a first antenna segment including at least a first phase shift element configured to reduce the phase shift of the carrier signal within the at least a first antenna segment.

17 . The method of claim 16 , wherein the multi-segment loop antenna further comprising at least a second antenna segment including at least a second phase shift element configured to reduce the phase shift of the carrier signal within the at least a second antenna segment.

18 . The method of claim 17 , wherein the length of each antenna segment is no more than 25% of the wavelength of the carrier signal.

19 . The method of claim 18 , wherein at least one matching component configured to adjust the impedance of the multi-segment loop antenna assembly.

20 . The method of claim 13 , wherein the wavelength of the carrier signal is approximately thirteen inches.

21 . The method of claim 13 , wherein the inductive component includes:
at least one far field antenna assembly.

22 . The method of claim 21 , wherein the far field antenna assembly is a dipole antenna assembly.

23 . The method of claim 21 , wherein the far field antenna assembly includes a first antenna portion and a second antenna portion.

24 . The method of claim 23 , wherein the sum length of the first antenna portion and the second antenna portion is greater than 25% of the wavelength of the carrier signal.
