Abstract :
The gain factor of an offset-fed paraboloidal reflector is derived. The reflector is assumed to be in the far field of the feed, and the feed patterns are of the class 
. Results are presented as a function of the angular aperture 
, the offset angle 
, and even values of the feed-pattern parameter 
. Phase-error effects due to a displacement of the feed from the focal point are calculated. Displacements of 
, and 
are considered. The gain factor is again derived as a function of the previously mentioned parameters and the feed displacement 
.
