Conformai faraday cage micro-coaxial shielding for combined optimization of routing distribution and EM coupling reduction

This paper proposes an original approach developed for MMIC´s that allows optimizing high frequency signals isolation together with routing optimization. In fact, the proposed approach leads to a significant area reduction of the routing together with enhanced performances. Electrical performances of these interconnections are reported to area occupation compared to conventional micro strip and/or coplanar structures. It is observed that parasitic coupling is reduced by at least 23 dB at 5 GHz compared to classical isolation techniques. Based on the available data a BBS (Broad Band Spice) electrical model is proposed and compared to measurements. Deviation between both simulated and measured is found satisfactory.
