Abstract :
The beam squint phenomenon is of importance when antenna pointing performance is considered. This phenomenon is characterised in paraboloidal, Cassegrain and Gregorian antennas. Squint-predicting formulas are presented, squint-free conditions are outlined and an extension of these formulas to general multi-reflector antennas is suggested.
