Stripline for electromagnetic susceptibility testing — Input impedance matching

This paper is focused on input impedance optimization of a stripline. The stripline for electromagnetic susceptibility testing represents a radiating structure which is composed of one active and one or more grounded conductors. The characteristic impedance of the stripline is given by the dimension and the material between conductors. If the characteristic impedance does not match to the output impedance of the RF amplifier, the impedance mismatch occurs and output circuits of the amplifier could be destroyed. The impedance matching circuit is necessary to be used in this situation. The impedance matching of the stripline using attenuators is shown in this paper; simulation results of S-parameters for different attenuator types were discussed.
