Since the method of using GTEM cell to do EMI measurement is put forward, it gradually received the testers' attention because of the advantages of GTEM cell. In this paper, HFSS software is used to simulate a GTEM cell of classic structure, and the reliability of simulation is conformed from two aspects. The two aspects are characteristic impedance and output power of GTEM cell. The experiment result...
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...
At present there are several methods to do EMI measurements in GTEM cell, such as EDM, MDM, Linear, Wilsonpsilas method and so on. But the difference between the calculated results of these methods and the EMI results measured in OATS (open area test site) is very large in some situation. This article provides a new method to calculate electric field intensity in GTEM cell using the equivalent dipole...
