Abstract

Measurements taken between 28-30 July 2014. UHF tag on thin mylar backing measured firstly on an adjustable height stand at heights of 1.4m and 1.9m. Objective to assess and compensate for read range variation caused by ground/tag distance. Tag read performance measured for read powers of 33dBm, 30dBm, 26dBm, 20dBm, and 10dBm using Favit UHF RFID 7dBic patch antenna provided with the system. Measurements taken in open area with dry ground. Tag then attached to mature Oak tree at 1m, then 2m above ground and successful read over 5m between reader antenna established at 1.5m and 0.5m heights.

The read range data in the provided file has been compared with the open space Friis power relationship of received power being proportional to transmit power divided by transmission distance squared.
