Abstract :
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
