Multiple-Feed Antenna System Having Multi-Position Subreflector Assembly

A multiple-feed antenna system for communicating signals in a plurality of radio frequency (RF) ranges, the multiple-feed antenna system comprising:

• a subreflector configured to receive signals reflected from a primary reflector;
• a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges;
• a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges;
• and
• a motorized mechanism configured to change a relative position of the first feed and a position of the second feed with respect to the subreflector, the motorized mechanism being rotatable among multiple positions that include a first position and a second position, wherein:
• when the motorized mechanism is in the first position, a signal reflected by the subreflector enters the first feed;
• and
• when the motorized mechanism is in the second position, the signal reflected by the subreflector enters the second feed, wherein the first feed and the second feed are offset from a center portion of the primary reflector.

A method for communicating signals in a plurality of radio frequency (RF) ranges, comprising:

• providing a multiple-feed antenna system comprising:
• a subreflector configured to receive signals reflected from a primary reflector;
• a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges;
• a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges;
• and
• a motor configured to change a relative position of the first feed and a position of the second feed with respect to the subreflector;
• rotating the motor into a first position where a signal reflected by the subreflector enters the first feed;
• and
• rotating the motor into a second position where a signal reflected by the subreflector enters the second feed.
