Abstract
With the exponential grow of personal wireless devices, issues like power consumption, communication security and interference immunity are gaining more importance. Body Area Networks(BAN), due to their reduced range, are by nature relatively low power, but as an answer to achieve even a more confi ned range, Near Field Communications(NFC) and Body Coupled Communications (BCC)have been proposed. While the 1 st is used to link two devices that are physically very close, the BCC concept broadens the communication range to the region around the human body. One of the possible technologies supporting BCC is based upon relatively low frequency capacitive coupling. In this paper we propose a simple model for estimating the gain of a capacitive coupling system. This model has been validated by 3D electromagnetic simulations and double checked with practical experiments. The results are similar within an order of magnitude which, for the intended use of the model, proves to be accurate enough.
