Abstract

The invention relates to an antenna array used with a wireless subscriber unit. The antenna array can have a plurality of antenna elements attached to a housing. Expanding or collapsing the housing can move the antenna elements into an expanded or a collapsed state, respectively.

Claims

1. An antenna assembly for use with a wireless subscriber unit comprising:

a housing having a top housing portion and a bottom housing portion; and

a plurality of antenna elements having a top and a bottom, the top of the antenna elements attached to the top housing portion and the bottom of the antenna elements slidably mounted within the bottom housing portion such that expanding the top housing portion from the bottom housing portion expands the antenna elements and collapsing the top housing portion toward the bottom housing portion collapses the antenna elements.

2. The antenna assembly of claim 1 wherein the antenna assembly further comprises at least one circuit board mounted within the housing.

3. The antenna assembly of claim 1 wherein the antenna assembly further comprises a captive antenna circuit board, a captive modem controller circuit board and a captive transceiver circuit board.

4. The antenna assembly of claim 1 wherein the antenna assembly further comprises a port.

5. The antenna assembly of claim 1 wherein the antenna assembly further comprises a first securing mechanism to secure the top housing portion to the bottom housing portion when the antenna assembly is placed in a closed position.

6. The antenna assembly of claim 1 wherein the antenna assembly further comprises a second securing mechanism to secure the top housing portion away from the bottom housing portion when the antenna assembly is placed in an open position.

7. The antenna assembly of claim 1 wherein the plurality of antenna elements further comprise a plurality of captivating sleeves.

8. The antenna assembly of claim 1 wherein the plurality of antenna elements comprises five antenna elements.

9. The antenna assembly of claim 8 wherein a first antenna, a second antenna, a third antenna and a fourth antenna of the five antenna elements are positioned within the housing at locations corresponding to the corners of a square and a fifth antenna of the five antenna elements is positioned within the housing at a location corresponding to the center of a square.

10. The antenna assembly of claim 1 wherein the plurality of antenna elements comprises four antenna elements.

11. The antenna assembly of claim 10 wherein a first antenna, a second antenna, a third antenna and a fourth antenna of the four antenna elements are positioned within the housing at locations corresponding to the corners of a square.

12. The antenna assembly of claim 1 wherein the antenna elements comprise continuous rods.

13. The antenna assembly of claim 1 wherein the antenna elements comprise telescoping elements.

14. An antenna assembly for use with a wireless subscriber unit comprising:

a housing having a top housing portion and a bottom housing portion; and

a plurality of antenna elements having a top and a bottom, the top of the antenna elements attached to the top housing portion and the bottom of the antenna elements fixedly attached to the bottom housing portion such that expanding the top housing portion from the bottom housing portion expands the antenna elements and collapsing the top housing portion toward the bottom housing portion collapses the antenna elements.

15. The antenna assembly of claim 14 wherein the antenna assembly further comprises at least one circuit board mounted within the housing.

16. The antenna assembly of claim 14 wherein the antenna assembly further comprises a captive antenna circuit board, a captive modem controller circuit board and a captive transceiver circuit board.

17. The antenna assembly of claim 14 wherein the antenna assembly further comprises a port.

18. The antenna assembly of claim 14 wherein the antenna assembly further comprises a securing mechanism to secure the top housing portion to the bottom housing portion when the antenna assembly is placed in a closed position and to secure the top housing portion away from the bottom housing portion when the antenna assembly is placed in an open position.

19. The antenna assembly of claim 14 wherein the plurality of antenna elements comprises five antenna elements.

20. The antenna assembly of claim 19 wherein a first antenna, a second antenna, a third antenna and a fourth antenna of the five antenna elements are positioned within the housing at locations corresponding to the corners of a square and a fifth antenna of the five antenna elements is positioned within the housing at a location corresponding to the center of a square.

21. The antenna assembly of claim 14 wherein the plurality of antenna elements comprises four antenna elements.

22. The antenna assembly of claim 21 wherein a first antenna, a second antenna, a third antenna and a fourth antenna of the four antenna elements are positioned within the housing at locations corresponding to the corners of a square.

23. The antenna assembly of claim 14 wherein the antenna elements comprise telescoping elements.

24. The antenna assembly of claim 14 wherein the plurality of antenna elements comprise a flex circuit material.

25. The antenna assembly of claim 24 wherein the flex circuit forms an accordion antenna.

26. The antenna assembly of claim 24 further comprising a plurality of support rails.
