Stacked patch antenna and method of operation therefore

1. A stacked antenna, comprising:

a first patch including at least one slot part thereon;

a second patch including at least one strip part thereon; and

wherein said at least one slot part of said first patch at least partially crosses over or partially crosses under said at least one strip part of said second patch and 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.

2. The stacked antenna of claim 1 , wherein said at least one slot part is formed by at least one notch in said first patch.

3. The stacked antenna of claim 1 , wherein said at least one strip part is formed by at least one hole in said second patch.

4. The stacked antenna of claim 1 , further comprising at least one additional patch, said at least one additional patch includes at least one slot part thereon if said at least one additional patch is adjacent to a patch that contains at least one strip part or at least one strip part if said at least one additional patch is adjacent to a patch with at least one slot part thereon.

5. The stacked antenna of claim 1 , further comprising a feedpoint associated with said first or said second patch.

6. The stacked antenna of claim 1 , further comprising a ground plane adjacent to said first or said second patch.

7. The stacked antenna of claim 1 , wherein the area where said at least one slot part of said first patch is substantially over said at least one strip part of said second patch creates a slot-strip coupling region.

8. A stacked antenna, comprising:

a first patch including at least one strip part thereon;

a second patch including at least one slot part thereon; and

wherein said at least one strip part of said first patch at least partially crossing over said at least one slot part of said second patch and said first patch is diamond shaped patch with at least one hour glass-shaped notch and said second patch is a hexanonal patch with a dumbbell hole.

9. The stacked antenna of claim 8 , wherein said at least one slot part is formed by at least one notch in said second patch.

10. The stacked antenna of claim 8 , wherein said at least one strip part is formed by at least one hole in said first patch.

11. The stacked antenna of claim 8 , further comprising at least one additional patch, said at least one additional patch includes at least one slot part thereon if said at least one additional patch is adjacent to a patch that contains at least one strip part or at least one strip part if said at least one additional patch is adjacent to a patch with at least one slot part thereon.

12. The stacked antenna of claim 8 , further comprising a feedpoint associated with said first or said second patch.

13. The stacked antenna of claim 8 , further comprising a ground plane adjacent to said first or said second patch.

14. An apparatus, comprising:

at least one patch antenna including a hole therein forming at least one strip portion thereon; and

at least one additional patch antenna including at least one notch therein forming at least one slot portion thereon, said at least one-slot like portion at least partially covering, or at least partially being covered by, said at least one strip portion thereby forming a slot-strip coupling region and wherein said at least one patch is a rectangular patch with at least one rectangular notch and said at least one additional patch is a rectangular patch with a rectangular hole.

15. A method for reducing the size of a patch antenna, comprising:

coupling at least one rectangular patch with at least one additional rectangular patch by forming at least one slot-strip coupling region between said at least one patch and said at least one additional patch, said slot-strip coupling region formed by said at least one patch including a hole therein forming at least one strip portion thereon and said at least one additional patch including at least one rectangular notch therein forming at least one slot portion thereon, said at least one-slot portion at least partially covering, or at least partially being covered by, said at least one strip portion thereby forming said coupling region.

16. The method of claim 15 , wherein said at least one slot-strip coupling region is two slot-strip coupling regions.

17. The method of claim 15 , further comprising providing a ground plane adjacent to said at least one patch or adjacent to said at least one additional patch.

18. The method of claim 15 , further comprising feeding an RF signal to said at least one patch or at least one additional patch via a feedpoint associated with said at least one patch or said at least one additional patch.

19. A stacked antenna, comprising:

a first patch including at least one slot part thereon;

a second patch including at least one strip part thereon; and

wherein said at least one slot part of said first patch at least partially crosses over or partially crosses under said at least one strip part of said second patch and 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.

20. A stacked antenna, comprising:

a first patch including at least one slot part thereon;

a second patch including at least one strip part thereon; and

wherein said at least one slot part of said first patch at least partially crosses over or partially crosses under said at least one strip part of said second patch and 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.
