摘　　要：罗兰C全向磁天线体积小、信噪比高、不需接地的优点使得其成为国内接收机生产厂家研究的热点;文中详细介绍了罗兰C磁天线设计制作过程及其接收罗兰C信号的特点和特性,重点研究了全向磁天线的组合环路设计和全向磁天线原理样机的结构设计,给出了详细的设计步骤和测试结论;在原理样机的基础上,进行了电、磁天线实测罗兰C信号的对比分析试验,试验结果表明设计的磁天线接收信号强度和功率均高于电天线,且磁天线接收信号的信噪比要高于电天线。Omni-directional H-field antenna had more advantages than E-field antenna,such as small volume,high SNR and no grounding needed,which was studied by many receiver manufacturing enterprises.The thesis introduced the process of designing omni-directional H-field antenna and analyzed the characteristics of omni-directional H-field antenna,at the same time,the combinational loop and the structure of prototype omni-directional H-field antenna were studied in detail.The experiments of receiving signal were done by using the H-field and E-field antenna.The results of experiments indicated that H-field antenna could get bigger voltage range and higher power of the signal than E-field antenna;furthermore,using H-field antenna could get higher SNR.
