US 10,122,085 B2 · Feed re-pointing technique for multiple shaped beams reflector antennas

Abstract

Systems, methods, and apparatus for re-pointing at least one beam are disclosed. In one or more embodiments, the disclosed method involves receiving and/or transmitting, with at least one feed, electromagnetic (EM) energy towards a non-parabolic reflector. In at least one embodiment, reflected EM energy that is reflected from the non-parabolic reflector originates from and/or generates at least one beam. The method further involves rotating, at least one feed, from at least one first angular position to at least one second angular position, such that at least one beam shifts from at least one first coverage location to at least one second coverage location.

Dependent claims

A method for re-pointing at least two beams, the method comprising:

at least one of directly receiving and directly transmitting, with at least two feeds, electromagnetic (EM) energy towards a non-parabolic reflector, which comprises one of a diverging surface or a converging surface,
wherein reflected EM energy that is reflected from the non-parabolic reflector at least one of originates from and generates the at least one beam;
and
rotating each of the at least two feed to different angular positions than original angular positions of each of the at least two feeds such that the at least two feeds are configured in one of a diverging feed pointing configuration or a converging feed pointing configuration, thereby shifting each of the at least two beams to different coverage locations than original coverage locations of each of the at least two beams.
