Abstract

An antenna system comprises: multiple antenna elements; and multiple beam forming networks configured to produce radiation patterns for both receiving and transmission functions configured to be optimized by re-positioning said antenna elements, wherein said beam forming networks comprise a receiving beam forming network configured to combine multiple first inputs from said antenna elements into at least a first output, and a transmission beam forming network configured to divide a second input into multiple second outputs to said antenna elements.

Claims (26)

1. An antenna system comprising:

multiple antenna elements;

and multiple beam forming networks configured to optimize produced radiation patterns for both receiving and transmission functions by spatial re-positioning of said antenna elements relative to each other via an iterative optimization processing to meet multiple constraints to said radiation patterns for said both receiving and transmission functions concurrently.

2. The antenna system of claim 1 further comprising a re-positioning mechanism configured to alter positions of said antenna elements so as to re-position said antenna elements.

3. The antenna system of claim 1 further comprising a reflector illuminated by said antenna elements.

4. The antenna system of claim 3 , wherein one of said antenna elements is on a focal plane of said reflector.

5. The antenna system of claim 3 , wherein one of said antenna elements is defocused away from a focal plane of said reflector.

6. The antenna system of claim 1 , wherein said constraints comprise a minimum gain and direction of a beam peak of one of said radiation patterns for said receiving function.

7. The antenna system of claim 1 , wherein said constraints comprise a minimum gain and direction of a beam peak of one of said radiation patterns for said transmission function.

8. The antenna system of claim 1 , wherein said constraints comprise a maximum gain and direction of a beam null of one of said radiation patterns for said receiving function.

9. The antenna system of claim 1 , wherein said constraints comprise a maximum gain and direction of a beam null of one of said radiation patterns for said transmission function.

10. The antenna system of claim 1 , wherein said constraints comprise a maximum gain and direction of a beam null of one of said radiation patterns for said receiving function, and a maximum gain and direction of a beam null of one of said radiation patterns for said transmission function.

11. An antenna system comprising:

multiple antenna elements; and

a beam forming network configured to optimize a produced radiation pattern for a receiving function by spatial re-positioning of said antenna elements relative to each other via an iterative optimization to meet a constraint to said radiation pattern for said receiving function.

12. The antenna system of claim 11 , wherein said constraint comprises a minimum gain and direction of a beam peak of said radiation pattern for said receiving function.

13. The antenna system of claim 11 , wherein said constraint comprises a maximum gain and direction of a beam null of said radiation pattern for said receiving function.

14. The antenna system of claim 11 further comprising a re-positioning mechanism configured to alter positions of said antenna elements so as to re-position said antenna elements.

15. The antenna system of claim 11 further comprising a reflector illuminated by said antenna elements.

16. An antenna system comprising:

multiple antenna elements; and

a beam forming network configured to optimize a produced radiation pattern for a transmission function by spatial re-positioning of said antenna elements relative to each other via an iterative optimization to meet a constraint to said radiation pattern for said transmission function.

17. The antenna system of claim 16 , wherein said constraint comprises a minimum gain and direction of a beam peak of said radiation pattern for said transmission function.

18. The antenna system of claim 16 , wherein said constraint comprises a maximum gain and direction of a beam null of said radiation pattern for said transmission function.

19. The antenna system of claim 16 further comprising a re-positioning mechanism configured to alter positions of said antenna elements so as to re-position said antenna elements.
