采用矩量法分析了安装在金属圆柱筒上的套筒天线。研究了这种新型套筒天线的输入阻抗、电压驻波比(VSWR)、增益及辐射方向图等电特性。设计出了工作在105~420MHz频段和225~600MHz频段的实用天线,分析结果与实验结果吻合良好。
Using the moment method, the sleeve antenna mounted on a metal cylinder is analyzed. The input impedance, voltage standing wave ratio (VSWR), gain and radiation pattern of the new sleeve antenna are studied. Designed a practical antenna operating in the 105 ~ 420MHz band and 225 ~ 600MHz band, the analysis results agree well with the experimental results.
