Methodology for RF receiver sensitivity analysis using electromagnetic field map

Accurate modelling of a chip is a very important factor when analysing and predicting radio-frequency (RF) receiver sensitivity. Chip modelling based on the tangential electromagnetic (EM) field from the near-field measurement just above the top surface of the chip is introduced, and a methodology utilising three-dimensional (3D) EM simulation, for predicting receiver sensitivity generated by the chip-noise of a mobile phone, is suggested. It is worth noting here that the calculation of absolute coupling values between a noise source and an antenna is possible by using the real measured data source to obtain reliable results.
