What UHF tag read range do you need?

2017-12-22 View:

“Everyone wants a small tag with long range – it’s probably the single most wished-for tag people ask me about. 

They only have room for a 1” by 1” tag, but they want to read it from 40 feet away. And that’s something that physics just cannot deliver in an inexpensive, passive UHF tag
Generally speaking,” he explains, “with passive tags, the longer the read range, the bigger the antenna.

“Do you want to read items from a distance, like for identifying inventory in a warehouse, or is this a security or authentication application, where you’d want the tag to come into much closer contact with a reader before registering? Be ready to answer those types of questions, because read range definitely influences tag selection.”

A close read range for passive UHF RFID tags is generally less than 3 feet, while mid-range is between 3 and 9 feet, and long range is closer to 9 to 20 feet. While antennas and readers can be calibrated to different levels of sensitivity, tag read range cannot greatly outperform their physical limitations.
