【摘要】 本文以宽带无线电引信系统天线为研究背景，研究微带天线小型化、宽带技术，设计用于无线电引信系统的小型化宽带微带天线。文中选择与引信弹体共形的环形微带天线作为设计方案，通过对环形微带天线加载电阻，实现天线的小型化和高带宽；使用基于矩量法的电磁仿真软件对天线进行分析，并对天线参数进行了测量，给出了天线性能的仿真和测试结果。结果表明，本文设计的加载环形微带天线具有带宽高、体积小等优点，适合在宽带无线电引信系统中使用。更多还原

【Abstract】 Regarding the antennas of broadband radio fuze system as research background, we study the compact and broadband technology of microstrip antennas in this paper, and design the compact and broadband microstrip antennas used in radio fuze system. We choose a project with loaded annual ring microstrip antenna, and the character of compact and broadband is achieved by loading a chip-resister to the antenna. The antenna is analysed by the software based on MOM. The results of simulation and measurement indicate that the antenna designed in this paper has advantages of broadband and compact size, and it is suitable for broadband radio fuze system.更多还原
