Dual-band communication satellite system and method

Dual-band satellite communication systems and methods are described. A dual-band satellite communication system is described with an array of feeds. The array includes single band feeds and one or more multi-band feeds. The multi-band feeds provide dual-band spot beams. Dual-band spot beams include...

Zusammenfassung:	Dual-band satellite communication systems and methods are described. A dual-band satellite communication system is described with an array of feeds. The array includes single band feeds and one or more multi-band feeds. The multi-band feeds provide dual-band spot beams. Dual-band spot beams include a first frequency band spot beam and a second frequency band spot beam. A spot beam layout may be provided when a shared reflector for the array of feeds is provided. The first frequency band beamwidth may be smaller than a second frequency band beamwidth and the number of multi-band feeds in the array of feeds may be less than the number of single band feeds.
