同轴波纹喇叭内部高频馈源特性研究

Study of Inner High Frequency Feeds of Coaxial Corrugated Horn

同轴波纹喇叭可用作双频段馈源或多频段馈源。纵槽波纹喇叭可以作为同轴波纹喇叭的内部高频馈源,除具有良好的辐射特性外,还具有较小的口面面积。文中利用模式匹配法对同轴馈源的内部高频馈源进行理论分析与研究,并对实际馈源进行了测试。实测结果与计算结果基本一致,从而验证了分析方法的正确性。

Coaxial corrugated horns can be used as dual-frequency or muti-frequency feeds. The corrugated horns with axial slots, with good radiation and small size, can be used as the inner high frequency feeds of the coaxial corrugated horns. The inner high frequency feeds are analyzed and studied by use of mode matching method, and tested practicality. The measured consequence and theoretic computation are basically identic, which validates the method.
