摘  要:四脊型宽带宽波束圆极化喇叭天线因其扇形波束和圆极化特性在电子自卫干扰设备中应用广泛。分析表明,采用非等化对脊结构四脊喇叭体与异型介质移相片结合可实现3:1工作带宽,新颖的层叠介质透镜在解决波束展宽的同时实现2.4:1.0轴比带宽,整体指标已接近国外类似产品。研究表明,该设计方法可作为解决宽带宽波束圆极化喇叭天线小型化有效途径之一。Four ridge broadband and wide beam circularly polarized horn antenna is widely used in electronic self-defense jamming equipment because of its sector beam and circular polarization characteristics.The analysis shows that the combination of non-equivalent to the ridge structure four ridge horn body and the heteromorphic medium transfer photo can be achieved 3:1 working bandwidth.The new laminated dielectric lens can achieve 2.4:1.0 axial ratio bandwidth while solving beam broadening.The overall index is close to similar products abroad.Research shows that this design method can be used as one of the effective ways to solve miniaturization of the broadband and wide beam circular polarization horn antenna.
