摘要：
Accurate estimation on the direction and the amount of beam squint is important in many applications of modern reflector antennas. This paper characterizes the beam squint phenomenon in circularly polarized fed paraboloidal, Cassegrain, and Gregorian antennas. Geometrical optics (GO)/aperture field method is used to derive generalized squint-predicting formulas, the accuracy of which are verified by computer simulations based on diffraction analysis. From these formulas, the squint-free conditions are developed. An extension of these formulas is suggested to predict the squint angles for general multireflector antennas.
