UHF Passive Tag Principle
• Backscatter radio; reader sends commands and offers CW
• Tag doesn’t send anything, it just modulates it’s reflectivity
• Tag only needs Microwatts of power for the IC
• The power is harvested from the reader carrier

Field Regions
• Reactive near field• Non-radiating field components (electric field or magnetic field) dominate
• Tag affects antenna properties (matching, bandwidth)
• Radiating near field• Radiating fields dominate• Angular field distribution is dependent on distance from antenna
• Far field• Only radiating field components are significant• Fields can be approximated as plane waves• Power density decays as the inverse square of distance
• Field region limits are approximate and depend on the wavelength and the dimensions of the antenna

Forward Link Physics
• The power density at the tag location is
• ISO uses electric field strength at the tag location as a measure of tag sensitivity
• However, sensitivity can also be expressed as power on the tag. The effective aperture of an isotropic antenna is
• Thus, power on the tag is

Reader-based Measurements
• Typically where everyone starts
• Measuring read-range• Hold the tag and walk away from the reader
• Reliability of reader functionality?• Is the limiting factor forward or return link?
• What is the effect of the environment?
• Attenuating transmitted and received signal• Keep the measurement distance constant
• Measure how much attenuation can be added to each path, so that the tag can still be read
![Page 17: FromResearchto Business: Case Voyantic · 2018-11-29 · Voyantic Ltd. Voyantic provides RFID measurement and testing solutions • Installation base of over 600 systems on five continents](https://reader034.vdocuments.site/reader034/viewer/2022042420/5f376c9ff3552d65e719464a/html5/thumbnails/17.jpg)
Threshold Measurement
• Challenging the power source of the tag, i.e. findingthe minimum power required to activate the tag
• Procedure1. Start from a transmit power where the tag does not
respond2. Send a command to the tag3. Check if there is a response
1. If yes, you have found the threshold transmit power2. If no, increase power and return to 2
4. Use knowledge of measurement geometry to calculate a comparable value such as electric field strength, power on tag, read range
5. Repeat with different frequencies, orientation, materials, external interfernce etc.

Voyantic provides RFID measurement and testing solutions • Installation base of over 600 systems on five continents](https://reader034.vdocuments.site/reader034/viewer/2022042420/5f376c9ff3552d65e719464a/html5/thumbnails/18.jpg)
Backscatter Measurement
• Measure the strength (and phase) of the signal returning from the tag
• Use a coherent (superheterodyne) receiver
• Repeat with different transmit powers, frequencies, materials etc.
• What to measure:• Received signal includes carrier leaking from the transmitter
• Power distribution: If a carrier of power P is modulated with binary 100% ASK (OOK), the total power is P/2, which is divided between the carrier and the sidebands, P/4 each
![Page 19: FromResearchto Business: Case Voyantic · 2018-11-29 · Voyantic Ltd.

Theoretical Read Ranges
• Read ranges are an intuitive way to assess tag performance
• The forward link and return link should be assessed separately
• Forward link: What would the acquired read range be with the maximum allowed transmit power (e.g. 2 W erp) if the response can always be detected and decoded?
• Return link: What would the acquired read range be if the tag is always powered up and a receiver with a given sensitivity and antenna gain (e.g. -70 dBm and 4dBi) is used?

• Check IC impedance and design a matching antenna?
• To learn about the old school tag design RF side of things, check Monza 1&2 datasheets

“Thank you for the update. Unfortunately
I will not be at RFID Journal LIVE as most
travel has been suspended and RFID has
been greatly scaled down here. Any
additional spending for RFID equipment is
unlikely for the remainder of the calendar
year and likely beyond.”
“XXX is still struggling financially.I don’t think we’ll be able to purchaseany new equipment until Q1 ‘2010. Please keep in touch.”

Going Back to 2008-2009:What Did We Do?• Entering Japanese market was crucial
• Changes in organization• Management job rotation• Bring in office manager
• The market recovered in Spring 2010 and the work started to pay off
• We did attempt Market Development and Product Development as well
• Expanding to system integrators has not really worked out
• Production testing did, but a lot slower than we expected

Testing with reader is not enough
42
Narrow frequency
Power output variation
poor and detuned tags may appear to be exactly as sensitive as good ones, if checked on single frequency.
Accuracy of the output power is poor and not calibrated, distinguishing difference is uncertain.
functionality testing ≠ performance testingTesting at reader frequency does not consider detuning.

Example of variation in UHF Tags
Roll of 7000 UHF tags measured in production with:
- Tagsurance UHF
- Snoop Pro UHF near field coupling element

6 tags were chosen and picked out:
- Chosen to represent the overall variation
- Chosen tag responses highlighted in the graph

Variation detected in near field and far field
45
6 chosen tags were measured also in far field:
- There’s offset both in frequency and power domain between near field and far field
- But the differences between tags are similar in both
- This is the case only with Snoop Pro near field coupling

Tag Variation in Application Point of View
• This is how the tag was designed to work
• 6-8m read range both free air and plastic
• This was found with 6 chosen tags from the same roll of 7000 tags
• 2-8m read range in free air
• 5-10m read range on plastic

Antenna Radiation Pattern Measurements
The radiation pattern of an antenna can be measured easily by turning the antenna into an ad-hoc RFID tag.
1. Terminate the antenna with a connectorized RFID tag chip.
2. Measure the orientation sensitivity of the “tag” and normalize the results.

RFID Sensors
There are several different ways to design an RFID sensor. Depending on the type, testing may include RF tests and/orprotocol level testing.
