Read range
The environment influences the HF field of the integrated antenna, making it impossi‐
ble to provide a “clear” demarcation of the sensing range.
•
Application-specific reflections can result in both overreaches and “holes”
(destructive interferences).
•
Other factors that can significantly impact the read range include:
°
Transponder quality: The quality depends on the antenna gain, the integrated
transponder chip and its sensitivity, the reflected energy.
°
Material of the carrier object (plastic, wood, metal)
°
Objects between the device and transponder that can affect the UHF field
(items, liquids, people)
In addition to the read results, the device can also output diagnostic data. The diagnos‐
tic data provides an indication of the write and read quality. This diagnostic data can be
used to achieve optimum read results when setting up the system.
The radiation pattern shown here for the device’s antenna was obtained in a reproduci‐
ble environment (absorber chamber as a reflection-free space) for illustrative purposes.
The diagram shows how the UHF field propagates in the reflection-free space, but
cannot be used to draw any conclusions on the likely sensing range in a real application
on-site.
