Summary:
This study discusses the suitability of numerical methods as robust analysis and prediction tools regarding the RF performance of CAD derived mobile phones. The investigation was conducted using one of the latest commercial quad-band mobile phones and in addition included head and different hand models targeting a detailed assessment of in-use situations. In particular, the effect of the user’s hand position on the antenna performance was given a special focus. In the simulation different parameters were evaluated such as impedance, efficiency, far-field, as well as EM near-field distributions. The results are compared to measurements obtained with the latest tools available. The resulting reliable prediction for various daily usage configurations demonstrate the usability of numerical methods in the early design phase of devices such as complex high-end multi-band mobile phones.
