Abstract
The use of sensor transponder technologies in medicine opens valuable possibilities in therapy of human cardiovascular system diseases, for example cardiac insufficiency. This paper deals with the question, what relevant effects exist concerning energy transmission through the human body and how they can be considered during the system design process. Parasitic effects in the transponder antenna are analysed. Finally, a combination of all effects is taken into account to analyse the frequency behaviour of the whole system. Practical examinations confirm the feasibility with a HF transmission system.
