Abstract
A multifrequency antenna includes a main reflector for signals in a low frequency band. One or more portions of the main reflector are deformed to provide one or more auxiliary reflectors for signals in one or more higher frequency bands. The feed for the low frequency band is located axially of the main reflector, while the feeds for the higher frequency bands are offset to the side of the low frequency feed. The lateral and axial offsets of the vertex of an auxiliary high frequency reflector from the vertex of the main low frequency reflector and the focal length of the auxiliary high frequency reflector are selected to minimize the degradation of the performance in the low frequency band.
Claims15
A multifrequency antenna comprising:
- a main reflector for signals in a first frequency band, a portion of the surface of said main reflector being deformed in curvature to form an auxiliary reflector for signals in a second frequency band higher than said first frequency band, the deformation of curvature being such as to minimize degradation of the performance of said main reflector.
