Abstract
In this paper the feasibility of balanced antenna structures in the mobile terminal environment has been investigated concerning bandwidth and radiation properties. It has also been studied if the effect of the user´s hand on frequency de-tuning and decrease in radiation efficiency could be reduced with the balanced antenna structures compared to the traditional antenna structures. In addition, emphasis has been put on the specific absorption rate (SAR) and hearing-aid compatibility (HAC) performance of balanced antenna structures.
