摘要
TEM喇叭是一种超宽带天线,已广泛应用于瞬变电磁场的研究中,本文提出了分析和设计具有波形保真性能的TEM喇叭的新概念和计算方法,介绍了实际制作的加脊圆锥TEM喇叭,并给出了实验结果,表明它具有良好的阻抗特性和波形保真性,对瞬变场和超宽带雷达的研究具有很好的理论和实用价值.
TEM Horn is an ultrawideband (UWB) antenna which is widely used in the research of transient electromagnetic field. A novel design concept and calculation method have been presented in this paper. According to this concept, a ridged conical TEM horn has been designed and fabricated. The experiment results show that its waveform fidelity and impedence performance are excellent. so it is very valuable for the study of transient field and UMB radar.
