Frequency Range

The standard frequency range of 12 MHz – 16 MHz is often sufficient, when testing a tag applied on the item intended, or a packaged tag. The extended frequency range is a valuable tool in cases where further processing or the use environment is expected to tune the response. With the extended frequency range of 10 MHz – 30 MHz, the Tagsurance HF provides visibility over the entire operating bandwidth of an inlay or a tag. This allows detecting the variance also far beyond the typical read frequencies.

The operating frequency range of an HF tag is highly dependent on the use case. The reader uses 13.56MHz frequency and this is targeted to be the center frequency of the tag, the frequency, where the tag is most sensitive and least power is required from the reader to wake up the tag in the end
application.

When an HF tag is placed on material, or near to other tags, the tag frequency response changes. For example in document tagging the individual HF tags resonance frequency is tuned up to 15MHz higher than the reader frequency, to compensate the effect of other tags in the stack and to provide the best application performance.
