Abstract

Systems and methods for mitigating interference from a satellite gateway antenna are disclosed herein. In an embodiment, a method for mitigating interference from a satellite gateway antenna includes locating a satellite gateway antenna that shares a frequency band with a 5G service, determining that the satellite gateway antenna causes radiation that interferes with a base station operating using the 5G service, and mounting at least one panel to reduce the radiation in a direction of the base station operating using the 5G service.

First claim

What is claimed is:

1. A method for mitigating interference from a satellite gateway antenna, the method comprising:
locating a satellite gateway antenna that shares a frequency band with a 5G service;
determining that the satellite gateway antenna causes radiation that interferes with a base station operating using the 5G service; and
mounting at least one panel to reduce the radiation in a direction of the base station operating using the 5G service.

2. The method of claim 1 , wherein
mounting the at least one panel comprises positioning the at least one panel a distance from the satellite gateway antenna using a support structure separate from that of the satellite gateway antenna.

3. The method of claim 1 , wherein
determining that the satellite gateway antenna causes radiation that interferes with the base station comprises creating a power flux density contour of an area surrounding the satellite gateway antenna and determining the base station to be within the power flux density contour.

4. The method of claim 1 , comprising
mounting the at least one panel to have an azimuthal rotation relative to a look direction of the satellite gateway antenna in a horizontal plane.

5. The method of claim 1 , comprising
mounting the at least one panel to have an upward tilt such that any reflection of horizontal rays of the radiation off of the at least one panel is not in a horizontal plane.

6. The method of claim 1 , comprising
mounting at least one panel on a side of the satellite gateway antenna to reduce a back lobe of radiation extending behind the satellite gateway antenna.

7. The method of claim 1 , comprising
mounting the at least one panel in front of the satellite gateway antenna to reduce a front lobe of radiation extending in front of the satellite gateway antenna at or near a look direction of the satellite gateway antenna.

8. The method of claim 1 , wherein
locating the satellite gateway antenna that shares the frequency band with the 5G service includes determining that the satellite gateway antenna is configured to transmit in a Ka or V uplink band.

9. The method of claim 1 , wherein
determining that the satellite gateway antenna causes radiation includes determining that the satellite gateway antenna causes radiation in multiple directions in a horizonal plane, and
mounting the at least one panel includes mounting a first panel in a first direction of the base station and mounting a second panel in a second direction of radiation exceeding −77.6 dBm/m 2 /MHz at a 10 meter height.

10. The method of claim 1 , wherein
mounting the at least one panel includes mounting a first panel positioned and arranged to reduce a back lobe of radiation extending behind the satellite gateway antenna and mounting a second panel positioned and arranged to reduce a front lobe of radiation extending in front of the satellite gateway antenna.

11. A satellite communication system comprising:
a satellite gateway antenna supported by a first supporting structure and located proximal to a base station operating using a 5G service; and
at least one panel supported by a second supporting structure separate from the first supporting structure of the satellite gateway antenna, the at least one panel positioned and arranged to reduce radiation from the satellite gateway antenna in a direction of the base station.

12. The satellite communication system of claim 11 , wherein
the at least one panel comprises a panel located on a side of the satellite gateway antenna to reduce a back lobe of radiation extending behind the satellite gateway antenna.

13. The satellite communication system of claim 11 , wherein
the at least one panel comprises two panels located on opposite sides of the satellite gateway antenna to reduce back lobes of radiation extending behind the satellite gateway antenna on the opposite sides of the satellite gateway antenna.

14. The satellite communication system of claim 11 , wherein
the at least one panel comprises a panel in front of the satellite gateway antenna to reduce a front lobe of radiation extending in front of the satellite gateway antenna at or near a look direction of the satellite gateway antenna.

15. The satellite communication system of claim 11 , wherein
the at least one panel is positioned and arranged to have an upward tilt such that any reflection of horizontal rays of the radiation off of the at least one panel is not in a horizontal plane.

16. The satellite communication system of claim 11 , wherein
the at least one panel is positioned and arranged to have an azimuthal rotation relative to a look direction of the satellite gateway antenna in a horizontal plane.

17. The satellite communication system of claim 11 , wherein
the at least one panel is not electrically or mechanically attached to the satellite gateway antenna.

18. The satellite communication system of claim 11 , wherein
the satellite gateway antenna includes a main reflector, a sub reflector and a feed horn, and the first supporting structure is configured to support the main reflector, the sub reflector and the feed horn.

19. The satellite communication system of claim 11 , wherein
the at least one panel includes a first panel and a second panel,
the first panel is positioned and arranged to reduce a back lobe of radiation extending behind the satellite gateway antenna,
the second panel is positioned and arranged to reduce a front lobe of radiation extending in front of the satellite gateway antenna.

20. The satellite communication system of claim 11 , wherein
the satellite gateway antenna is configured to transmit in a Ka or V uplink band.
