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, variant configurations have been computed and comparisons are given. A dedicated FE-based program has been applied. The radiation patterns have been obtained by evaluating the vectorial Huygens principle
