摘　　要：通过分析TEM喇叭天线的阻抗匹配特性和远场辐射特性,设计了一种新型指数线形TEM喇叭天线。与传统的TEM喇叭天线相比,新型指数线形TEM喇叭天线在全频段内减小了天线的反射系数,提高了低频时天线的辐射效率,拓展了天线的带宽。验证实验表明,该天线带宽为800MHz~6GHz,尺寸为20cm×20cm×20cm,同时兼顾了天线的小型化与超宽带。By analyzing the impedance matching and far-field radiation characteristics of TEM horn antenna,a novel exponential linear TEM horn antenna is designed. Compared with the traditional TEM horn antenna,the new exponential linear TEM horn antenna reduces the reflection coefficient of the antenna in the whole frequency band,increases the radiation frequency of the antenna at low frequency,and expands the bandwidth of the antenna. The experimental results show that the bandwidth of the antenna is 800 MHz ~ 6 GHz,the size is 20 cm × 20 cm × 20 cm,and the miniaturization and ultra-wideband of the antenna are considered.
