Abstract

Aspects of the present disclosure may be directed to a wrap-around antenna capable of being wrapped around a support structure to provide antenna patterns for a communication system. Such an assembly may be aesthetically pleasing and, because the antenna assembly allows for radiation away from the support structure, scattering effects due to interference from the support structure may be eliminated.

Claims

1. An antenna comprising:

an antenna assembly comprising a plurality of antenna columns arranged to be connected to form a perimeter about a central region, wherein each of the plurality of inter-connected antenna columns includes one or more radiating elements;

at least one power divider configured to distribute radio frequency (RF) signals received by a base station or combine signals received from at least one of the plurality of inter-connected antenna columns;

a plurality of respective enclosures housing the plurality of antenna columns respectively, wherein the at least one power divider is enclosed within one of the plurality of enclosures.

2. The antenna of claim 1, further comprising:

one or more RF connectors configured to couple the plurality of antenna columns to a base station.

3. The antenna of claim 1, wherein one of the plurality of enclosures is connected to another enclosure of the plurality of enclosures via at least one hinge.

4. The antenna of claim 3, wherein the one of the plurality of enclosures and the other enclosure are pivotable about a central axis of the at least one hinge.

5. The antenna of claim 1, wherein at least one of the one or more radiating elements is configured to operate in a first frequency band, and at least one other of the one or more radiating elements is configured to operate in a second frequency band different from the first frequency band.

6. The antenna of claim 1, wherein the plurality of antenna columns comprise three or more inter-connected antenna columns.

7. The antenna of claim 1, wherein the antenna assembly is configured to be mounted around a support structure.

8. An antenna assembly for a base station antenna configured to radiate one or more quasi-omnidirectional antenna patterns, the antenna assembly comprising:

a plurality of antenna columns configured to be inter-connected in a side-by-side relationship to form a perimeter about a central region, wherein each of the plurality of inter-connected antenna columns includes one or more radiating elements;

a single power divider configured to;

distribute signals received by a base station; and

combine signals received from one or more of the inter-connected antenna columns; and

a plurality of respective enclosures configured to enclose the plurality of inter-connected antenna columns, wherein the plurality of enclosures is further configured to enclose the single power divider, wherein adjacent enclosures of the plurality of enclosures are configured to be connected by at least one hinge.

9. The antenna assembly of claim 8, wherein the adjacent enclosures are pivotable about a central axis of the at least one hinge.

10. The antenna assembly of claim 8, wherein the antenna assembly comprises three or more antenna columns.

11. The antenna assembly of claim 8, wherein at least one of the inter-connected antenna columns comprises:

one or more first-band radiating elements configured to operate in a first frequency band, and one or more second-band radiating elements configured to operate in a second frequency band.

12. The antenna assembly of claim 8, wherein the base station antenna comprises a small-cell antenna.

13. The antenna assembly of claim 8, wherein the antenna assembly is configured to be mounted around a support structure.

14. An antenna assembly comprising:

a plurality of antenna columns configured to be arranged in a side-by-side relationship about a circumference of an upwardly extending portion of an upwardly extending member of a support structure, wherein each of the plurality of inter-connected antennas includes one or more radiating elements;

a single power divider configured to;

distribute signals received by a base station;

or

combine signals received from one or more of the inter-connected antenna columns; and

a plurality of respective enclosures configured to enclose the plurality of antenna columns, respectively, wherein adjacent enclosures are configured to be connected by at least one hinge.

15. The antenna assembly of claim 14, wherein the single power divider is positioned internal to a first enclosure of the plurality of respective enclosures.

16. The antenna assembly of claim 15, further comprising radio frequency (RF) cables configured to transmit signals from the single power divider to each of the antenna columns, wherein at least one of the RF cables is coupled to one of the antenna columns enclosed by a second enclosure of the plurality of respective enclosures, and is coupled to another one of the antenna columns via at least one jumper.

17. The antenna assembly of claim 16, wherein the at least one jumper is external to each of the plurality of respective enclosures.

18. The antenna assembly of claim 14, further comprising RF cables configured to transmit signals from the single power divider to each of the antenna columns, wherein at least one of the RF cables is enclosed by a flexible conduit between two of the antenna columns.

19. The antenna assembly of claim 18, wherein the flexible conduit is positioned between the support structure and one or more of the plurality of enclosures.

20. The antenna assembly of claim 14, wherein the single power divider is positioned external to the each of the plurality of enclosures, and wherein each of the inter-connected antenna columns is configured to produce independent sectored antenna patterns.
