INTEGRATED MULTI-BEAM ANTENNA RECEIVING SYSTEM WITH IMPROVED SIGNAL DISTRIBUTION
First Claim
1. An integrated multibeam antenna receiving system capable of receiving signals from a plurality of satellites and serving a plurality of Integrated Receiver-Decoder (IRDs), comprising:
- a plurality feed elements, each capable of receiving signals from one of the satellites;
an RF switch comprising a plurality of inputs coupled to the plurality of feed elements, and a plurality of outputs of total number equal to the number of the plurality of IRDs, each input of the switch representing a possible feed selection, and the outputs representing selected transponder outputs requested by the IRDs; and
,a low noise block (LNB) assembly receiving signals from the RF switch and providing IF signals in the desired frequency ranges.

Abstract
An integrated multi-beam antenna receiving system controls signal flow to a set of frequency translation devices in order to provide the required signals requested by Integrated Receiver Decoder units (IRDs, or set-top-boxes) within the home. The receiving system is compatible with legacy IRDs, or can support delivery of the requested signals in digital format allowing single coaxial cable or twisted pair delivery into the home. The system supports satellite reception from a mixed constellation of Direct Broadcast Satellites (DBS) and Fixed Satellite Service platforms operating in multiple frequency bands.
