  • Method and apparatus for receiving dual band signals from a common orbital location with an outdoor unit using a frequency selective subreflector and additional antenna feed
    Patent number: 7639980
    Abstract: A system 10 that includes a first satellite 14 at a first orbital slot B includes a first transponder 32 generating a first downlink signal at a first frequency and a second downlink signal at a second frequency. An outdoor unit 50 is directed toward the first satellite 14. The outdoor unit includes a support structure 80 and a reflector 64 coupled to the support structure 80 and reflecting the first downlink signal from a first satellite. A first reflector reflects the second downlink signal from the first satellite. A first feed 66 is coupled to the support structure and receives the first downlink signal. A reflector 72 having frequency selective surface 74 coupled to the support structure 80 reflects the second downlink signal and passes the first downlink signal therethrough. The second feed 70B is coupled to the support structure 80 and receives the second downlink signal reflected from the frequency selective surface 74.
