摘要
渐近线喇叭天线的传输模式为TEM波,因此不会产生色散,引起波形畸变,是辐射脉冲电磁波的理想天线。通过对渐近线喇叭天线组成各部分的设计与分析,介绍了一个应用于高能脉冲辐射条件下的渐近线喇叭天线的设计实例,具体描述了解决耐功率和驻波问题的方法,并进行了性能比较。测试和使用结果表明,所提方法切实可行,天线具有良好的阻抗特性和辐射特性,具有很好的实用价值。
TEM horn is an ideal choice for radiating pulse electromagnetic wave because the transmission mode in this kind of antenna is TEM mode, thus no dispersion and waveform aberration is induced. A modified TEM horn used as high power pulse radiator is given in this paper,design and analysis of the horn is presented in details. Results of simulation and measurement indicate that excellent impedance and radiation characteristics can be achieved using the method presented in this paper.
