The Influence of the Geometric Shapes of the Component Elements of the Planar Filter on its Parameters

Today, in the age of 4G and 5G technologies, the continuous development of high-tech devices through their minimization and various forms of design for their components that need to comply with EMC standards, make the analysis and design of EMI filters to be a research topic of great interest that will certainly stay that way for many more years. In this context, the present paper proposes the analysis of the influence of the geometric shapes of the elements that compose a planar EMI filter on its parameters. On one hand, we will follow the self-parameters of the component elements, and on the other hand, the minimization of the parasitic parameters will be followed. The analyzes will be performed on a low pass filter, which is the main element of the filter for the suppression of the electromagnetic interferences.
