本文讨论了体上通信天线的最佳选择。几种不同的天线，包括单极天线、环形天线、贴片和贴片阵列已经在体内环境中制造和测试。特别是，已经针对一系列身体姿势执行了两个在体路径的路径增益测量。很明显，单极天线在大多数测量情况下表现最佳。路径损耗的一阶分析（包括根据链路几何形状推导的天线增益和适合路径距离的自由空间损耗）给出的结果对于大多数身体姿势而言测量结果在 10 dB 以内。
The optimum choice of antenna for on-body communications is discussed in this paper. Several different antennas, including the monopole, the loop and patch and patch arrays have been fabricated and tested in the on-body environment. In particular, path gain measurements of two on-body paths has been performed for a range of body postures. It is clear that the monopole antenna performs best in most of the measurement cases. A first order analysis of the path loss, consisting of antenna gain deduced from link geometry and a free space loss appropriate to the path distance, give results that are within 10 dB of measurements for most body postures.
