摘要 研究一种超宽带TEM喇叭天线。提出一种无需加载的超宽带TEM喇叭天线的设计思路,理论推导该天线的远区场,由此得到特性阻抗变化与反射系数的关系。利用电磁仿真软件Ansoft HFSS模拟分析,在此基础上,设计一种视轴长度10cm的此类型TEM喇叭天线。测量得到在100～550MHz天线驻波比小于2.0,结果表明此天线在不加载情况下,通过对其结构进行合理的弯曲设计,也能使其具有良好超宽带特性。 A ultrawide-bandwidth TEM horn antenna is proposed in this paper.Far field pattern of the antenna is theoretically derived,and thus the relation between the variation of characteristic impedance of TEM wave and reflection coefficient is obtained.The antenna without resistive loading is simulated and analyzed with electromagnetic software Ansoft HFSS.Based on this,a TEM born antenna with 10 cm practical axial length is designed,the VSWR of less than 2.0 is measured within the antenna bandwidth from 100～550 MHz.The experiment result indicates that the antenna,without resistive loading,and through the structured curving,could be of good wideband feature.
