| 摘 要： | 为解决超宽带引信发射机与天线带宽、功率匹配的问题，设计了一种超宽带无线电引信天线。借助CST电磁场仿真软件对三角对称振子天线的馈电点和张角天线性能进行了仿真优化，通过分析其驻波比、天线带宽、天线增益和辐射信号幅度，可得出三角对称振子天线的最佳馈电点为三角形顶端、最佳张角为60°以及时域分析法更适合于超宽带无线电引信天线的仿真与优化。

| Abstract: | A new ultra-wideband radio antenna is designed for the match of ultra-wideband fuze transmitter with antenna bandwidth and power. The feeding point and opening angle of triangular symmetrical dipole antenna are optimized by CST. The results show that the best feeding point of the ultra triangular symmetrical dipole antenna is at the top, and the best opening angle is 60°. The time domain analysis is more suitable for the simulation and optimization of radio antenna by analyzing the voltage standing wave ratio (VSWR), antenna bandwidth, antenna gain and radiation signal amplitude of ultra-wideband radio antenna. |
