Novel Test Set Up for GTEM Cell Characterization

摘要

The GTEM cell is a new version of the modified transmission line, operated at very high-frequency test equipment for EMI or EMC measurement. The equipment is designed for an electromagnetic compatibility, immunity and radiated emissions test. In this paper, GTEM is designed using ANSYS HFSS 13.0 and fabricated for 1 to 3.9?GHz frequency. This paper focuses mainly on the novel validation test for the manufactured GTEM cell characterization without using costly Vector Network Analyzer. The novel test set up comprises of GTEM cell, transmitter and the receiver is designed and tuned at 2.4?GHz. Using this set up field uniformity is checked for fabricated GTEM ranges within +/? 6dB. This makes a compact and cost-effective novel test validation set up for the designed, developed and manufactured GTEM for 1 to 3.9?GHz.
