a second patch including at least one strip part formed from a hole in said second patch and at least one slot part formed from at least one notch in said second patch; and
wherein said at least one strip part of said first patch is at least partially crossing over or at least partially crossing under said hole in said second patch and said at least one slot part of said first patch is at least partially crossing over or at least partially crossing under said strip part of said second patch.
2. The stacked antenna of claim 1 , further comprising at least one additional patch, said at least one additional patch includes at least one strip part formed from a hole in said at least on additional patch and at least one slot part formed from at least one notch in said at least one additional patch,
wherein said at least one strip part of said at least one additional patch is crossing at least partially over or crossing at least partially under said hole in said first or second second patch and said at least one slot part of said at least one additional patch is crossing at least partially over or crossing at least partially under said strip part of said second patch.
3. The stacked antenna of claim 1 , wherein said first patch is a rectangular patch with at least one rectangular notch and said second patch is a rectangular patch with a rectangular hole.
4. The stacked antenna of claim 1 , wherein said first patch is an elliptical patch with at least one bowtie notch and said second patch is a triangular patch with an I-shaped hole.
5. The stacked antenna of claim 1 , wherein said first patch is a diamond shaped patch with at least one hour glass-shaped notch and said second patch is a hexagonal patch with a dumbbell hole.
6. The stacked antenna of claim 1 , further comprising at least one feedpoint associated with said first or said second patch.
7. The stacked antenna of claim 1 , further comprising a ground plane adjacent to said first or said second patch.
8. The stacked antenna of claim 1 , wherein the placement of said first patch in relation to said second patch create at least two orthogonal planes of symmetry.
9. A stacked antenna, comprising:
an upper patch including at least one strip part formed from a hole in said upper patch and at least one slot part formed from at least one notch in said upper patch;
a lower patch including at least one strip part formed from a hole in said lower patch and at least one slot part formed from at least one notch in said lower patch; and
wherein said at least one strip part of said upper patch is at least partially crossing over said at least one notch in said lower patch.
10. The stacked antenna of claim 9 , wherein a portion of said at least one strip part of said lower patch is at least partially crossing under hole in said upper patch.
11. The stacked antenna of claim 9 , further comprising at least one micro strip feed capable of connecting the ground plane with said lower patch.
12. The stacked antenna of claim 11 , wherein said antenna is dual polarized.
13. The stacked antenna of claim 9 , wherein said hole in said lower patch is smaller than said hole in said upper patch.
14. The stacked antenna of claim 9 , wherein said hole in said lower patch is a cross bowtie shaped and wherein said hole in said upper patch is a cross bowtie shaped.
15. The stacked antenna of claim 9 , further comprising at least one additional patch, said at least one additional patch includes at least one strip part formed from a hole in said at least on additional patch and at least one slot part formed from at least one notch in said at least one additional patch,
wherein said at least one strip part of said at least one additional patch is at least partially crossing over said at least one notch in said upper patch.
16. The stacked antenna of claim 9 , wherein said upper patch is rectangular and said slot part is formed on at least one corner of said rectangle by a notch formed on at least one corner of said rectangular upper patch.
17. The stacked antenna of claim 9 , wherein said lower patch is rectangular and said slot part is formed on at least one corner of said rectangle by a notch formed on at least one corner of said rectangular lower patch.
18. A method for constructing a patch antenna, comprising:
coupling an upper patch with a lower patch, said upper patch including at least one strip part formed from a hole in said upper patch and at least one slot part formed from at least one notch in said upper patch and said lower patch including at least one strip part formed from a hole in said lower patch and at least one slot-like part formed from at least one notch in said lower patch; and
wherein said at least one strip part of said upper patch is at least partially crossing over said at least one notch in said lower patch.
19. The method of claim 18 , wherein said at least one slot-coupling region is two slot-strip coupling regions.
20. The method of claim 18 , further comprising connecting a ground plane with said lower patch with a microstrip feed.
