摘　　要：本文介绍一种新型喇叭天线——带相位校正隔片式E面扇形喇叭。该喇叭的工作机理是藉助于在喇叭中重新分配能量和金属加速透镜方法使喇叭口径上分别获得电场幅度锥削和等相位。与通常的E面扇形喇叭比较,新设计的喇叭天线具有较低的副瓣电平、宽的张角和较短的喇叭长度。此外,测试结果表明,本文所述新喇叭的工程设计方法是合理的,并已成功地用在一相控阵天线中作为辐射单元。In this paper,a now type of horn antcnna——E plane sectorial horn with amplitude taper and phase correction in the apcrture is presented. Operating mechanism of this horn is that amplitude taper and phase correction arc obtained by redistributing energy in horn arid metal aecelerated lens method respectively. Compared with conventional E plane scetorial horn,the horn antenna of the latest design have low sidelobe level,short physical length and wide flare angle. Besides,test results show that engineering design method of this horn deseribed above is reasonable and it has been applied in a phase array antenna as a radiating clement successfully.
