| 摘 要： | 以天线口径效率为目标,研究了四脊喇叭口径对馈源波束等化、波束宽度恒定和天线口径效率等性能的影响,得到了一种3∶1带宽高效率圆四脊喇叭馈源的设计。该馈源在整个频带内具有较低的电压驻波比,三个主平面的主极化方向图波束等化较好,-10d B波束宽度基本恒定,且天线口径效率达到55%以上。

| Abstract: | The antenna aperture efficiency is regarded as the goal of quad-ridged flare horn (QRFH) feed design and the effects of its diameter on beam symmetry, beamwidth constancy and antenna aperture efficiency are studied. A high-efficiency QRFH design with 3:1 bandwidth is given. The calculated results show that a low reflection, a main lobe with near-constant symmetrical beamwidth and more than 55% antenna aperture efficiency are realized across the bandwidth. |

| Keywords: | broadband high efficiency beamwidth constant quad-ridged flare horn |
