一种超宽频带高效率波纹喇叭的设计

设计了一种90°波纹喇叭作为天线馈源。由经典理论得出喇叭尺寸，利用HFSS进行仿真、综合优化，并根据某些关键尺寸对性能指标的敏感程度给出了合适的公差。工程实现表明：该波纹喇叭的仿真结果与实际测试结果基本一致；工作带宽〉40％，也验证了其超宽带特性。

The design of an ultra-wide band, high-efficiency corrugated horn

A 90° corrugated horn is designed as an antenna feeder. With the dimensions of the horn obtained via the classical theory, the simulation and comprehensive optimization are made through the HFSS. Besides, the suitable tolerance is given for the sensitivity of performance indexes based on some key dimensions. The engineering implementation indicates that the simulation results of the corrugated horn are basically consistent with actual test results, and the operating bandwidth is 〉 40% which verifies the UWB characteristics.
