UHF RFID tags from The Tag Factory successfully tested by EECC 
The RFID UHF transponder types - M-Crown (On-Metal), - M-Shield (On-Metal) and - Pallet Tag from TTF (The Tag Factory) were controlled and tested between the 16th August 2010 till 17th August 2010 by the EECC.
A series of five transponders were used and measured the following:
- Measuring the responsiveness of the frequency response of the tag; calculate the resultant reading distance of the line Reader to Tag (forward link).
- Measuring the signal power of the reflected signal of the frequency response, the tag response; at the respond threshold; calculate the resultant reading distance of the line Tag to Reader (back link).
- Measuring of the transponder tags („median tag“) for three frequencies (European/US/Japan) regarding directionality
Test description
All transponder measurements were performed in the EECCs own high frequency absorption test room (anechoic chamber). A high frequency absorption test room is a metallic shielded measurement room which enables HF and UHF measurements to be standardised and reproduced. The special absorption walls are covered in specially formed structures to absorb, or at least dampen, electromagnetic waves. Under these conditions the RFID-Transponders can be tested and compared. They only receive the broadcast from the test antenna without any internal reflections.The test room fully meets the ETSI EN302 208-1. Inside the test room is a 360 degree turntable upon which a table made from special foam sits. This turntable and foam table has nearly no effect on the wave distribution. For the measurements a special reader is used from National Instruments (NI) PXI not a normal RFID reader. As a platform the PXI gives the best industry wide measuring system due to the high transfer speed and best latency times. The PXI system architecture is of a modular design and includes I/O Modules for high resolution, reproducible measurements. A self written EECC program is used to control the hardware and to interpret and evaluate the results.
Summary of the most important results
Each tag type is excellent all in all. Noticeable is that both “On Metal Tags (OMT)” (M-Crown / M-Shield) are very broadband concerning the forward link. All three important frequency bands are equally strongly supported. With regards to back link (back scatter) both the OMTs were very range limited in certain frequencies. This leads to some ranges being dependant on the forward link and some being dependant on the back link both being frequency dependant. The Pallet Tag showed over all frequencies a most excellent range with symmetrical send and receive properties. The directionality showed the typical performance of a dipole in the standard form of an 8.
