TEM喇叭天线阵元间互耦的研究
内容简介:TEM喇叭天线是一种典型的超宽带天线,已广泛应用于高功率脉冲辐射的研究中.应用FTT方法研究了TEM喇叭天线阵互耦特点,并从时域角度比较分析了阵间距离对互耦的影响,研究发现当天线阵在低频段阵间互耦较高、频段较强时,阵元间距越大,互耦越弱,而阵元间互耦可以改善阵列的低频辐射.
Abstract:TEM horn antenna is a typical ultra-wideband antenna which has been widely used in high-power pulsed radiation study. In this paper, the author used FIT method to study the characteristics of inter-element mutual cou- pling, analyzed how distance between array affect mutual coupling, and found out when the aerial array is in the low-frequency linear array, with higher frequency, distance between inter-element becomes longer and mutual cou- pling becomes weaker.The inter-element mutual coupling can improve the array of low-frequency radiation.
