A Design and Sumulation of Gigahertz Transverse Electromagnetic (GTEM) Cell
AbstractGigahertz Transverse Electromagnetic (GTEM) cell is a type of Electromagnetic Compatibility (EMC) testing room that is used for radiated emission testing. Of the several types of EMC test rooms, GTEM cells have advantages on the economic side compared to anechoic chambers. In this study a GTEM cell been designed and tested the results of the design in a simulation so when GTEM cell got fabricated at a higher stage it will get results that are in accordance with the parameters and need lower cost. GTEM cell is designed to work at a frequency of 300 MHz - 1 GHz with a length of 1.68 m, width 0.9 m and a height of 0.6 m. The GTEM cell design was tested to obtain the VSWR value, e-field response, return loss and shielding effectiveness. In this study design and simulation will be done by verifying the design results with the simulation results. The design and simulation of GTEM cell aims for radiated emission testing according to CISPR 22 standard and can be used as a reference in building a GTEM cell at a lower cost. The results of the GTEM cell design get the lowest return loss on -32 dB and the lowest VSWR on 1.04 at 890 MHz frequency. The average shielding effectiveness value is -1309 dB and the e-field response reaches 600 V / m
