文摘

The performance of a body area network (BAN) is strongly dependent on several parameters which make wireless communication quite challenging. For instance, the performance of the antenna itself could be affected by its geometric deformation when the structure is directly integrated into clothes. Operation of the antenna close to the human body necessitates adjusting its design for the intended applications whereas the maximum SAR value estimated in such conditions has to respect the standards. In this context, simulation tools that can take into account specific biological models offer a range of possibilities for investigating and optimizing the performance of BAN devices. Two different applications are presented here: the case of an RFID tag operating at 870 MHz, and a UWB antenna working in a frequency range between 3 and 6 GHz. The simulation tools developed by CST are used in this context to optimize the implementation of BAN devices shown in this paper.
