摘要

提出了采用一对反旋向平面端射圆极化可穿戴天线进行分集的体域通信抗多径接收方法，其原理是利用平面端射圆极化天线的俯仰面宽波束特性克服身高变化带来的幅度衰落，并利用其圆极化特性改善来波极化失配引起的深度衰落。在5.8 GHz频段上设计了天线实物，然后测量体域传播特性并建立离体分集信道模型，进而研制了信道仿真器，并与线极化天线分集情况进行比较。实验与仿真结果表明，同等条件下圆极化分集的等增益合并功率电平比线极化分集平均提升2.1 dB，多径均方根时延扩展及多径数显著降低，系统传输误码率可降低一个数量级，充分验证了体域圆极化天线分集接收方法的正确性及有效性。

Abstract

An anti-fading diversity receiving approach to body-area communications was proposed.A pair of opposite-sense called planar endfire circularly polarized antennas (PECPA) was employed to implement the receiving approach.The wide beamwidth CP characteristic of the PECPA was used to mitigate the height-dependent fadings.Antenna designs and body-area propagation measurements were performed at 5.8 GHz-band.An off-body channel model was established

and a channel simulator was accordingly developed.All results were compared to the cases using linearly polarized (LP) antennas diversity on equal conditions.The results show that the equal-gain-combination (EGC) signal levels for CP diversity reception are 2.1 dB greater than the LP one (with polarization mismatching loss removed).The rootmean-square delay spread (RDS) and number of multi-path component (MPC) can be significantly reduced.In addition

the simulated bit error rate (BER) of the body-area communication system using CP diversity can be improved by one order of magnitude compared the LP diversity one.The correctness and effectiveness of the proposed approach has been evidently validated by the experimental and simulated results.
