Influence of Adjacent Metal Cover Planes on EMC Filter Structures

This paper deals with the influence of metal cover planes close to SMD filter structures. The low-pass structures are used for EMC purpose and work in a frequency range of 100 kHz to 4 GHZ. It will be shown by measurement and simulation that a close cover plane changes the filter behavior significantly in dependency of the filter component used. For low and high impedance filter structures different influences are obtained; a parameter study was carried out in order to derive design rules. Key words: EMC, low-pass, conductive planes.
