The sensitivity test of 2.45GHz RFID active tag

Abstract

RFID active tag sensitivity is an important indicator of the tag, and its sensitivity is related to the location and orientation of the tag. However, in the actual application of the tag, its optimal working position and direction cannot be determined directly. Analysed the existing test method of active tag sensitivity, the test result of the tag sensitivity in any direction is used as the tag sensitivity. For the limitations of existing test methods, this paper presents a new idea and method for sensitivity testing of a 2.45GHz RFID active tag. Setting up the test environment used the biconical antenna, based on the sensitivity test in the stepping at the same angle in different directions, and the analysis algorithm based on measured data. The test experiment shows that the test result based on this method is rigorous and effective, and can be widely used in 2.45GHz RFID active tag sensitivity test.
