A compact Hertzian dipoles multiport model for near-field MIMO system assessment

The information flow rate in chips and also on circuit boards of modern electronic systems has developed into a bottleneck. Wireless ultrawideband (UWB) multi-input-multi-output (MIMO) chip-to-chip communication may provide a solution to this problem. The physical modeling of near-field MIMO systems requires network-oriented modeling accounting for the reciprocity of near-field MIMO antenna configurations. In this work we investigate a compact circuit model to assess near-field MIMO configurations and study a 2 × 2 MIMO test configuration for it potential with respect to its channel capacity under parameter variation concerning antenna positions and scatterers within the signal path.
