摘　　要：集群移动通信技术发展对天线小型化、轻量化提出了更高要求。加载技术是天线工程中常用小型化与宽带技术,论文采用磁振子加载集总电阻方法设计了小型化天线。利用电磁仿真软件HFSS,详细分析了电阻阻值对天线工作性能的影响,经过优化后的小型化天线工作频率为500MHz~660MHz,相对带宽达到了28.1%,整体尺寸小于十分之一波长,满足小型化设计目标。最后加工制作了天线实物,实测-10dB带宽为483MHz~661MHz,与仿真结果一致性较好,表明所设计天线的可靠性。The development of trunked mobile communication requires smaller and lighter antenna.Loading components is commonly used miniaturization and broadband technology.The miniaturized antenna which uses loaded magnetic ring is designed.The loaded resistance value on performance of antenna is analyzed in detail using scanning mode in HFSS.The working frequency of optimized antenna is from 550MHz~730MHz.The relative bandwidth of antenna reaches 28.1%and the size of antenna is smaller than the tenth wavelength,which required the designed goal.Finally,the real antenna is made and measured.The measured-10dB bandwidth is 483MHz~661MHz,which has great consistence with simulated result.The consistency of simulated and measured re⁃sults indicates that reliability of designed antenna.
