本文对超宽带天线分集技术及其对人体无线电传播信道的影响进行了实验研究和分析。各种分集合并技术被应用于突出;如何整体系统性能可以被增强。计算了五个不同的人体通道的分集增益，并讨论了分集分支天线之间的间距变化的影响，重点是互耦，相关性和功率不平衡。结果表明，重复性和可靠性的分析与误差变化低至0.8dB。该研究强调了分集技术在以身体为中心的无线通信中用于非视距传播场景的重要性。
This paper presents an experimental investigations and analyses of ultra-wideband antenna diversity techniques and their efiect on the on-body radio propagation channels. Various diversity- combining techniques are applied to highlight; how the overall system performance may be enhanced. Diversity gain is calculated for flve difierent on-body channels and the impact of variation in the spacing between diversity branch antennas is discussed, with an emphasis on mutual coupling, correlation and power imbalance. Results demonstrate the repeatability and reliability of the analysis with error variations as low as 0.8dB. The study highlights the signiflcance of diversity techniques for non-line-of-sight propagation scenarios in body-centric wireless communications.
