Eager to try out the new [Ultra-small UHF RFID Rain Tags](https://www.sparkfun.com/products/15116) it quickly became apparent that the trace antenna on the [M6E Nano Shield](https://www.sparkfun.com/products/14066) wasn’t going to cut it so we based a board on Murata’s reference design. So born was the UHF RFID Ring Antenna! This antenna does one thing and does it well – increasing the effective range of the Rain tags from (effectively) zero to about one inch. Ask any mathematician and they’ll tell you that’s a very good return!
This antenna is intended to be used in the UHF band (902MHz to 928MHz) and the [U.FL connector](https://learn.sparkfun.com/tutorials/three-quick-tips-about-using-ufl) makes it easy to connect to the M6E Nano or most other compatible RF products using a [U.FL to U.FL cable](https://www.sparkfun.com/products/15114). You can even use two through-hole locations to solder in place strain protection for the cable.
