A Method and Product for Evaluation RFID Tag Performance

Description

The present invention is a method for efficient calculation of the powering area of an RFID tag by use of a newly developed power-scaling factor. The method, when used in conjunction with the three-dimensional reader and tag antenna gains, can provide insight into the powering capability of the tag. Additionally, the power-scaling factor provides a new figure of merit that can be used to compare performance of RFID tags.
