International Classification:

H01Q 3/00
H01Q 19/00

US Classification:

343756, 343762

Abstract:

An antenna assembly is provided having a primary feedhorn arranged in a first plane and configured to provide a first scan pattern having a first gain and first beamwidth. In another embodiment, a plurality of feedhorns are configured to provide a second scan pattern, wherein each of the plurality of feedhorns may be oriented substantially parallel to the first plane. A support structure may be provided to arrange the primary feedhorn in the first plane and the plurality of feedhorns substantially in parallel to the first plane. According to another embodiment, the first and second scan patterns produce a resulting scan pattern having a resultant beamwidth greater than the first beamwidth and a resultant gain that is greater than a minimum gain requirement.
