Abstract

Systems, methods, and other embodiments associated with reflectors are described. One example system comprises a collection antenna. The system also comprises a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna.

First claim

What is claimed is:

1. A system, comprising:
a collection antenna;
a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna; and
a shield configured to prevent the designated signal from directly reaching the collection antenna and configured to prevent the non-designated signal from directly reaching the collection antenna
where the shield comprises a tile section and a cone section,
where the tile section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a first frequency range,
where the cone section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a second frequency, and
where the first frequency range and second frequency range are different.

2. The system of claim 1 , comprising:
an antenna array configured to determine a direction from a source of the designated signal,
where the reflector is moved to a position that causes the designated signal to be reflected to the collection antenna and to reflect the non-designated signal away from the collection antenna and
where the reflector is moved based, at least in part, on the direction.

3. The system of claim 1 , where the designated signal and the non-designated signal are of equal frequency and where the non-designated signal is of greater signal strength than the designated signal.

4. The system of claim 1 ,
where the reflector is at least one reflector plate that terminates at opposite ends with an elliptical shape.

5. The system of claim 1 ,
where a portion of the at least one reflector plate is flat and where the elliptical shape on each end is a substantially encompassed elliptical shape along a plane.

6. A system, comprising: a plurality of reflector plates configured to reflect a designated signal to a collection antenna and configured to reflect a non-designated signal away from the collection antenna, where the plurality of reflector plates comprises a first reflector plate and a second reflector plate; and a radio frequency shield configured to prevent the designated signal from directly reaching the collection antenna and to prevent the non-designated signal from directly reaching the collection antenna, where the shield is disposed between the first reflector plate and the second reflector plate; and an antenna array configured to determine a direction of a source of the designated signal; and a mechanism configured to cause the plurality of reflector plates to be positioned to a position such that a reflective portion of the plurality of reflector plates reflect the designated signal from the source to the collection antenna, where a determination of the position is based, at least in part, on the direction of the source, where the collection antenna comprises a radio frequency guard, where individual reflector plates of the plurality of reflector plates terminate at opposite ends with an elliptical shape, and where an angle the designated signal intersects with the plurality of reflector elates and an angle of the plurality of reflector plates to the collection antenna are used to determine the position.

7. The system of claim 6 , where the position is selected through a trial and error method.

8. The system of claim 6 ,
where the first reflector plate terminates at opposite ends with an elliptical shape.

9. The system of claim 8 ,
where the second reflector plate terminates at opposite ends with an elliptical shape.

10. The system of claim 6 ,
where at least a portion of the first reflector plate is flat.

11. The system of claim 10 ,
where at least a portion of the second reflector plate is flat.

12. The system of claim 6 ,
where the radio frequency shield comprises a tile section and a cone section,
where the tile section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a first frequency range,
where the cone section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a second frequency, and
where the first frequency range and second frequency range are different.

13. The system of claim 6 ,
where the plurality of reflector plates is two reflector places.

14. The system of claim 6 ,
where the plurality of reflector plates is more than two reflector places.

15. A system, comprising:
a collection antenna;
a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna; and
an antenna array configured to determine a direction from a source of the designated signal;
a shield configured to prevent the designated signal from directly reaching the collection antenna and configured to prevent the non-designated signal from directly reaching the collection antenna,
where the reflector is moved to a position that causes the designated signal to be reflected to the collection antenna and to reflect the non-designated signal away from the collection antenna,
where the reflector is moved based, at least in part, on the direction,
where the reflector is at least one reflector plate that terminates at opposite ends with an elliptical shape, and
where the collection antenna comprises a radio frequency guard.

16. The system of claim 15 ,
where the shield comprises a tile section and a cone section,
where the tile section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a first frequency range,
where the cone section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a second frequency, and
where the first frequency range and second frequency range are different.

17. A system, comprising:
a collection antenna; and
a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna;
where the reflector is at least one reflector plate that terminates at opposite ends with an elliptical shape,
where the reflector comprises a signal reflective side and a signal absorbent side, where the signal reflective side is more signal reflective than the signal absorbent side,
where the signal absorbent side is more signal absorbent than the signal reflective side,
where the opposite ends with the elliptical shape turn toward the signal absorbent side,
where a portion of the at least one reflector plate is flat, and
where the elliptical shape on each end is a substantially encompassed elliptical shape along a plane.

18. The system of claim 17 , comprising:
a shield configured to prevent the designated signal from directly reaching the collection antenna and configured to prevent the non-designated signal from directly reaching the collection antenna.

19. The system of claim 18 ,
where the shield comprises a tile section and a cone section,
where the tile section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is within a first frequency range,
where the cone section is configured to prevent the designated signal from directly reaching the collection antenna when the designated signal is w
