【 摘 要 】

In this paper, the GTEM cell electric field using to UHF sensor calibration is simulated by HFSS software. According to the simulation results, the field uniformity of the total electric field strength in the "1/3 area" of the GTEM cell can meet the requirements before being placed in the UHF sensor. However, the field uniformity of the total electric field strength has been greatly changed after the UHF sensor is placed. In addition, the maximum amplitude of the field strength change in the UHF sensor test area exceeds 10 dB compared to that before the UHF sensor is placed. It has a great influence on the calibration accuracy of UHF sensors. Through the simulation study of the electric field of GTEM cell, it provides a reference for further improving the calibration accuracy of UHF sensor.
