对馈电喇叭相位中心的概念进行了严格的研究，并使用高斯波束模式分析，详细研究了平衡混合模式下波纹馈电喇叭的几个不同定义的相位中心，包括最大增益相位中心。导出了这些相位中心位置的表达式，该表达式适用于宽范围的波纹角尺寸以及近场和远场距离。>
The notion of phase center for a feed-horn is critically examined, and, using Gaussian beam-mode analysis, several variously-defined phase centers, including a maximal-gain phase center, are investigated in detail for corrugated feed-horns in balanced hybrid mode. Expressions for the locations of these phase centers are derived which are applicable for a wide range of corrugated horn dimensions and for near-field as well as far-field distances. >
