Shielding_and_DecouplingLocalized Shielding Page-1 Shielding and EMI for Wireless Circuits By Allen Podell VP of Technology, Besser Associates With much material from Anatoli Tsaliovich Copyright 1999 A. Tsaliovich Courtesy of the author Localized Shielding Page-2 Introduction EMI and unwanted coupling between components or systems is being addressed by improved grounding, balanced lines, wideband decoupling chokes, and local shielding. The characteristics of local shielding are addressed in this talk, along with some other techniques for EMI mitigation, such as balanced lines, single point grounding, slotted ground planes, ferrite beads, and multiple bypassing. EM simulation is an invaluable tool when assessing the effectiveness of these techniques. Moreover, the improved speed of simulation has led to ……
