This paper describes the effort to miniaturize common mode filters based on electromagnetic bandgap structures. It describes the proposed approach by means of a systematic analysis of different configurations. The typical 3-patch configuration proposed in the past is modified removing the central patch and the bridge dimensions are tuned for keeping the same target frequency. The analysis of the crosstalk is carried out for the relevant configurations in order to assess the possible implementation of these structures in high density printed circuit boards. The simulation results are discussed and compared to identify the best miniaturized geometry for a practical implementation.

Abstract

This paper describes the effort to miniaturize common mode filters based on electromagnetic bandgap structures. It describes the proposed approach by means of a systematic analysis of different configurations. The typical 3-patch configuration proposed in the past is modified removing the central patch and the bridge dimensions are tuned for keeping the same target frequency. The analysis of the crosstalk is carried out for the relevant configurations in order to assess the possible implementation of these structures in high density printed circuit boards. The simulation results are discussed and compared to identify the best miniaturized geometry for a practical implementation.
