The information flow rate in chips and also on circuit boards is a limiting factor in the development of modern high-performance electronic systems. Wireless ultrawideband (UWB) multi-input-multi-output (MIMO) chip-to-chip communication has been considered as an option to mitigate these bandwidth limitations. The physical modeling of near-field MIMO systems requires network-oriented modeling accounting for the reciprocity of nearfield MIMO antenna configurations [1]. Nanoelectronics-based integrated circuits including also integrated antennas open new prospects for broad-band wireless chip-to-chip and board-to-board data transfer, and could facilitate wireless ultrawideband (UWB) multi-input-multi-output (MIMO) communication [2].
