Abstract :
With appropriate setup, shielded planar EM (electromagnetic) analysis can be used for antenna analysis. While shielded EM analysis can not handle the variety of antenna problems that unshielded analysis can, shielded analysis offers extreme numerical robustness. This robustness allows, in turn, rigorous identification, quantification, and elimination of analysis error sources. This robustness also allows perfectly calibrated groups of internal ports, unique to shielded EM analysis. This in turn leads to new efficient design methodologies and also allows a new compact model extraction (actually, synthesis) capability. These capabilities are described and illustrated with examples.
