Abstract

Claims (35)

1. An antenna reflector, comprising:

a central segment with a peripheral surface and a plurality of intermediate segments; each of the intermediate segments having an outer surface, an inner surface and two side surfaces;

a plurality of bodies; an end face separately coupled to each of the bodies;

the peripheral surface provided with more than one of the bodies;

the inner surfaces and the side surfaces each provided with at least one of the bodies;

the end faces of the peripheral surface and the end faces of the inner surfaces aligned to form a plurality of radial pairs configured for releasable connection to each other;

the end faces of the side surfaces adjacent to each other aligned to form a plurality of lateral pairs configured for releasable connection to each other;

at least one of the end faces of the radial pairs and of the lateral pairs extending proud of the respective peripheral surface, inner surfaces or side surfaces, whereby when the radial pairs and the lateral pairs are connected, the peripheral surface does not touch the inner surfaces and the adjacent side surfaces do not touch each other.

2. The reflector of claim 1 , wherein the end faces of at least one of the radial pairs and of the lateral pairs is provided with a cam arm on a first face and a cam pin on a second face; the cam arm pivotable to engage the cam pin, coupling the end faces together.

3. The reflector of claim 2 , wherein the cam arm has a groove which progressively engages the cam pin as the cam arm is pivoted from an open to a closed position.

4. The reflector of claim 1 , wherein the end faces of at least one of the radial pairs is provided with a locating pin on a first face and a socket on a second face; the locating pin seating into the socket as the end faces are mated together.

5. The reflector of claim 1 , wherein the end faces of at least one of the lateral pairs is provided with a tab on a first face and a slot on a second face; the tab seating into the slot as the end faces are mated together.

6. The reflector of claim 1 , wherein the coupling of the end faces to the central and intermediate segments is via a plurality of bodies coupled to the segments, the end faces removably connected to the bodies.

7. The reflector of claim 1 , wherein the radial pairs and the lateral pairs are coupled by a means for locking.

8. The reflector of claim 1 , wherein the end faces of at least one of the radial pairs are provided with an interlocking feature having two axis of alignment.

9. The reflector of claim 1 , wherein the end faces of at least one of the lateral pairs are provided with an interlocking feature having one axis of alignment.

10. The reflector of claim 1 , further including a plurality of peripheral segments; each of the peripheral segments having an inner surface, two side surfaces and an outer surface;

the peripheral segment inner surfaces and the peripheral segment side surfaces each provided with at least one of the bodies;

the outer surfaces of the intermediate segments provided with a least one of the bodies;

the end faces of the outer surfaces of the intermediate segments and the end faces of the peripheral segment inner surfaces aligned in peripheral radial pairs configured for releasable connection;

the end faces of the adjacent peripheral segment side surfaces adjacent to each other aligned in peripheral lateral pairs configured for releasable connection;

at least one of the end faces of the peripheral radial pairs and of the peripheral lateral pairs extending proud of the respective peripheral surface, inner surfaces or side surfaces, whereby when the peripheral radial pairs and the peripheral lateral pairs are connected, the intermediate segment peripheral surfaces do not touch the peripheral segment inner surfaces and the adjacent peripheral segment side surfaces do not touch each other.

11. The reflector of claim 10 , further including at least one rib; the rib coupled to the central segment and a peripheral segment by a plurality of fasteners.

12. The reflector of claim 10 , further including at least one notch in the outer surface.

13. An antenna reflector, comprising:

a plurality of segments, each of the segments provided with a plurality of end faces positioned along surfaces of the segments;

the end faces adjacent to each other arranged in a plurality of lateral and radial pairs, the lateral and radial pairs coupled together;

at least one of the end faces of the radial pairs and of the lateral pairs extending proud of the respective surfaces, whereby when the radial pairs and the lateral pairs are connected, the adjacent segments contact one another only via the radial and lateral pairs.

14. The reflector of claim 13 , wherein the connected segments form a parabolic reflector surface.

15. The reflector of claim 13 , wherein each of the end faces are removably coupled to a body, the bodies coupled to the segments.

16. The reflector of claim 13 , wherein the end faces of at least one of the radial pairs are provided with an interlocking feature having two axis of alignment.

17. The reflector of claim 13 , wherein the end faces of at least one of the lateral pairs are provided with an interlocking feature having one axis of alignment.

18. The reflector of claim 13 , wherein the end faces of at least one of the radial pair(s) and of the lateral pair(s) is provided with a cam arm on a first face and a cam pin on a second face; the cam arm pivotable to engage the cam pin, coupling the end faces together.

19. The reflector of claim 18 , wherein the cam arm has a groove which progressively engages the cam pin as the cam arm is pivoted from an open to a closed position.

20. The reflector of claim 13 , further including at least one rib; the rib coupled between a central segment and at least one adjacent segment by a plurality of fasteners, the at least one rib oriented normal to the central and at least one adjacent segment.
