Analysis of handset antennas in the vicinity of the human body by the electromagnetic simulator

As the capacity of a personal computer and workstation increases rapidly, m ana electromagnetic simulators solving antenna problems are widely used. In this: paper, the IE3D electromagnetic simulator, which is a commercial sof tware product, is applied to the analysis of handset antennas in the vicini ty of tile human body. Firstly, basic characteristics of popular handset an tennas such as whip and planar inverted-F antennas are obtained by the IE3D electromagnetic simulator and calculated results: are compared with measur ed results quoted from the referenced paper. Secondly, on tile basis of new ly considered design concept fur a handset antenna, a loop antenna system f ur the handset, which we have proposed in order to re duce tile influence o f human body, is taken as an example of a balance-fed antenna and is analyz ed theoretically and experimentally including the influence or tile human b ody. In a result, calculated results: by the IE3D electromagnetic simulator are ill good agreement with measured results and it is: confirmed that the simulator is very effective e in analyzing the handset antenna in the vici nity of tile human body.
