摘　　要：本文介绍一种在喇叭口径上具有幅度锥削的相位校正的E面扇形喇叭。在喇叭内部不同区域中重新分配能量和改变相速来获得幅度锥削和相位校正。与通常的E面扇形喇叭比较,这种喇叭具有较低的副瓣电平,短的喇叭长度和宽的张角。此外,测试结果表明,本文描述的设计方法是合理的,并成功地用在一相控阵天线中作为辐射单元。In this paper, an E—plane sectoral horn with amplitude taper and phase correction in the aperture is presented. The amplitude taper and phase correction are obtained by redistributing energy and changing phase velocity in different region inside the horn respectively. Compared with conventional Eplane sectoral horn, it has low sidelobe level, short physical length and wide flare angle. Besides, test resuits show that engineering design method described in the paper is reasonable and it has been applied in a phased array antenna as a radiating element successfully.
