The near‐field validation of computational electromagnetic models of personal wireless communication devices is becoming indispensable, especially, when assessing specific absorption rate (SAR) compliance to regulatory limits by computer simulation. A possible practice for such validation is to compare measured and simulated electromagnetic field distributions in a standard flat phantom designed for SAR compliance measurements. The authors recently presented an input impedance measurement‐based validation method. They extend their scheme with a deconvolution procedure. This enables near field validation based on the reconstructed E2 field obtained by the deconvolved measurement of the impedance change compared to the calculated E2. However, the reconstruction problem is inherently ill conditioned and requires numerical treatment. They demonstrate that the regularisation of the convolution matrix makes the reconstruction of the E2 field feasible with promising error. Through examples of a 1 GHz printed inverted F and a 1.8 GHz printed monopole antenna, they show that the mean‐square error as low as 1% between the original and the reconstructed E2 is achievable with the proposed method.
