Abstrakt EN: Unshielded stripline antenna is an essential instrument of electromagnetic compatibility studies. It is used primarily for generating uniform TEM field to test electromagnetic immunity. Defining the geometry of a stripline antenna could be a challenging task for a specified frequency range. It is due to various limiting factors; among them is the impedance of a stripline. Various approximation formulas used at present are adequate only if the ground plane is much larger than stripline and in proximity to it, which is not the case of a stripline antenna for EMC tests. This study demonstrates two approaches—2D static and 3D time harmonic—to the finite element simulation of a stripline in order to predict its impedance. The results demonstrate good agreement between two approaches. The developed 2D FEM model is a rigorous way for defining the optimal geometry of a stripline.
