Abstract

An antenna system for wireless communications and other wireless applications is disclosed. In one particular embodiment, the antenna system may comprise a frame with at least three facets and an antenna element mounted on each of the at least three facets, wherein each of the antenna elements are electromagnetically isolated from each other.

Claims

1. An antenna system comprising:

a frame with at least three facets; and

an antenna element mounted on each of the at least three facets, wherein each of the antenna elements are electromagnetically isolated from each other.

2. The antenna system of claim 1, wherein the antenna elements are electromagnetically isolated from each other with greater than 10 dB of orthogonality.

3. The antenna system of claim 1, wherein the antenna elements are electromagnetically isolated from each other with greater than 20 dB of orthogonality.

4. The antenna system of claim 1, wherein the antenna elements are electromagnetically isolated from each other with between 25 and 30 dB of orthogonality.

5. The antenna system of claim 1, wherein the antenna elements are mounted to the frame in a fixed manner.

6. The antenna system of claim 1, further comprising:

an enclosure, wherein the antenna elements are located entirely within the enclosure.

7. The antenna system of claim 1, wherein the frame defines an opening between a top of the frame and a bottom of the frame.

8. The antenna system of claim 1, wherein the frame allows for circulation of air through the frame.

9. The antenna system of claim 1, wherein the frame comprises four facets.

10. The antenna system of claim 1, wherein the frame comprises eight facets.

11. The antenna system of claim 1, wherein first and second antenna elements are mounted on first and second opposing facets and oriented vertically, and wherein third and fourth antenna elements are mounted on third and fourth opposing facets and mounted diagonally in opposite directions from each other.

12. The antenna system of claim 11, wherein the first and second opposing facets are angled inward between 5 and 25 degrees, and wherein the third and fourth opposing facets are angled inward between 0 and 5 degrees.

13. The antenna system of claim 1, wherein the antenna elements are placed less than one wavelength away from each other.

14. The antenna system of claim 1, wherein the antenna elements are placed less than one half wavelength away from each other.

15. The antenna system of claim 1, wherein the antenna elements are placed less than one quarter wavelength away from each other.

16. The antenna system of claim 1, wherein the antenna elements are omnidirectional antennas.

17. The antenna system of claim 1, further comprising:

a heatsink; and

a circuit board,

wherein the heatsink is located between frame and the circuit board.
