Abstract :
A standard WLAN-antenna operating at 2.4 GHz, connected to a PC-notebook has been investigated. In practise, both the presence of human biological tissue and of the notebook casing influence the antenna radiation pattern significantly. For determining the distortion, several numerical investigations have been accomplished. Thereby, more and less favorable polarization directions have been investigated. A dedicated FEM-based as well as a FDTD-based program have been applied and the results have been compared
