| 摘 要： | 以超宽带窄脉冲辐射为应用背景,通过添加补偿回路并调整回路的大小,设计了一种具有低频补偿的超宽带TEM喇叭天线.利用FDTD方法对天线结构进行了仿真,分析了不同补偿回路大小时TEM喇叭天线的S11参数、相位特性、辐射带宽及前后向辐射场等参数,得到了在大于400 MHz频带范围内S11参数低于-10 dB的天线结构.制作天线原型,并进行了实际测试,频域S11参数测试结果与仿真结果基本吻合.通过对时域波形的分析可知,该天线具有较高的波形保真度. |

| Abstract: | By adding a loop and properly adjusting the loop structure,an UWB TEM horn antenna with low-frequency compensation is designed.The S11 parameter,phase characteristic and bandwidth of TEM horns with different loop size are simulated and analyzed using FDTD.The designed antenna is capable of operating in a very wide bandwidth,defined by a-10 dB S11.The prototypes of the antenna is manufactured and tested.The simulation result is in good agreement with the result obtained by measurement,and the antenna is show... |
