Reliable prediction of mobile phone performance for different daily usage patterns using the FDTD method

The objective of this study was to evaluate whether the performance of mobile phones can be reliably predicted by numerical methods. It has previously been demonstrated [1, 3] that performance can be accurately assessed for standardized testing positions at the head. In this study, the requirements were extended to actual usage patterns such as different positions at the head and especially for different ways of holding the phone with the hand. The latter is of particular importance because fingers placed at certain locations could strongly affect the antenna.
