Abstract
An antenna assembly to be carried by a satellite includes an antenna feed configured to extend outwardly from the satellite, and a frame rotatably carried by the antenna feed and is rotatable about a first rotation axis. A main reflector is carried by the frame and is aligned with the antenna feed. A splash plate is carried by the frame in spaced apart relation from the main reflector and is rotatable about a second rotation axis.
Claims22
An antenna assembly to be carried by a satellite and comprising:
- an antenna feed configured to extend outwardly from the satellite;
- a frame rotatably carried by said antenna feed and being rotatable about a first rotation axis;
- a main reflector carried by said frame and aligned with said antenna feed;
- and
- a splash plate carried by said frame, and positioned in spaced apart relation from said main reflector without a subreflector therebetween so that said main reflector is positioned along a path between said antenna feed and said splash plate, and so that said splash plate is rotatable about a second rotation axis.

A satellite comprising:
- a housing;
- communications circuitry carried by said housing;
- and
- an antenna assembly comprising
- an antenna feed configured to extend outwardly from said housing and coupled to said communications circuitry,
- a frame rotatably carried by said antenna feed and being rotatable about a first rotation axis,
- a main reflector carried by said frame and aligned with said antenna feed, and
- a splash plate carried by said frame, and positioned in spaced apart relation from said main reflector without a subreflector therebetween so that said main reflector is positioned along a path between said antenna feed and said splash plate, and so that said splash plate is rotatable about a second rotation axis.

A method for making an antenna assembly to be carried by a satellite and comprising:
- positioning an antenna feed to extend outwardly from the satellite;
- positioning a frame to be rotatably carried by the antenna feed, with the frame being rotatable about a first rotation axis;
- positioning a main reflector to be carried by the frame and aligned with the antenna feed;
- and
- positioning a splash plate to be carried by the frame, and positioning the splash plate in spaced apart relation from the main reflector without a subreflector therebetween so that the main reflector is positioned along a path between the antenna feed and the splash plate, and so that the splash plate is rotatable about a second rotation axis.
