摘要

本文介绍了一种用于平方公里阵列的宽带馈电，覆盖2.8-5.18 GHz。首先，在现有设计的基础上研制了一种宽喇叭，结果并不令人满意。因此，该设计优化了紧凑的尺寸和更高频率下的更好性能。仿真结果表明，重新设计的混合槽喇叭具有良好的阻抗和辐射性能。采用形状SKA碟形光学系统，模拟孔径效率达到86%以上，在工作频带内满足灵敏度要求。

Wideband wide flared corrugated horns designed for the Square Kilometre Array

This paper presents the development of a wideband feed for the Square Kilometre Array, covering 2.8-5.18 GHz. At the start, a wide flared horn is developed based on an existed design and the results are not satisfactory. Hence this design is optimized for compact size and better performance at higher frequency. The simulation results show the redesigned horn with hybrid slots achieves excellent impedance and radiation performance. The simulated aperture efficiency is above 86% with shaped SKA dish optics, and the required sensitivity is satisfied over the operating frequency band.
