For a UWB communication system, by using differential characteristic of Herz magnetic dipole antenna, the narrow pulse can be produced from the rise edge of input square-wave signal.
在UWB通信中，利用赫兹磁偶极子天线的微分特性，由输入方波的上升沿产生窄脉冲。
So the selective of the transitional waveguides should be decided according to the large port or the narrow port as the input port.
因而应根据过渡波导是宽端口输入还是窄端口输入来选用过渡波导。
The result showed that the analyzer has wide input frequency range, narrow RBW (Resolution Bandwidth) and high scanning accuracy, and it reaches the international advanced level.
测试结果表明所设计的分析仪输入频带宽、频率分辨力和扫频准确度高，达到国际同类产品先进水平。
