Research on the Directivity Test of RFID Tag in GTEM Cell

摘要

The paper can demonstrate that the directivity test of RFID tag using GTEM cell has a good agreement with the test in free space, by theoretical analysis and mathematical calculation. At the same time, we do the directivity test with GTEM cell and UHF RFID tag, and can finally verify the feasibility of GTEM cell in doing directivity test, and raise a new low-cost, efficient testing method for the directivity test of RFID tag.
