“…Equivalent current models were used to estimate the spatial distribution of the near‐field coupling from the IC to the antennas while maintaining a fixed position of the IC. To investigate the positional impact of ICs on RFI, a simulation‐based position optimization procedure for ICs has been proposed . The idea was to represent the IC radiation response with a small loop structure and characterize the positional variation of near‐field coupling from the loop to the antennas.…”

In this article, an optimization procedure for the placement of integrated circuits (ICs) for reduced radio‐frequency interference (RFI) in mobile devices is presented. The concept of a power conversion factor (PCF) is introduced to quantify the near‐field radiation of ICs based on near‐field measurement techniques. For PCF extraction, equivalent source antennas are designed to represent the radiation chracteristics of ICs. In addition, the concept of a power transfer function (PTF) is also introduced to characterize the near‐field propagation from RFI noise sources to the built‐in antennas in mobile devices. From the combination of the PCFs and the PTFs, a spatial near‐field specification of ICs for reduced RFI is proposed. Based on the proposed specification, the application example of an optimized IC placement in mobile platform design is presented. © 2016 Wiley Periodicals, Inc.
