Abstract

The subject disclosure relates to solar energy collection and use in communications systems and to enhancements thereof. In an aspect, dual function antennas are disclosed that can simultaneously function as an antenna and as a solar energy collection system. In further aspects, disclosed embodiments can focus incident solar radiation to increase output voltage of conventional solar cells. Measured and simulated results demonstrate various aspects of the subject disclosure.

First claim

What is claimed is:

1. A solar energy collection antenna, comprising:
a suspended plate antenna (SPA) element coupled to a reflective ground plane, wherein the SPA element is adapted to enhance reflected solar radiation associated with the reflective ground plane; and
at least one solar cell adapted to receive at least a portion of the reflected solar radiation.

2. The solar energy collection antenna of claim 1 , wherein the SPA element is adapted to receive excitation via an L-probe proximate to the reflective ground plane.

3. The solar energy collection antenna of claim 1 , wherein the reflective ground plane is further configured as a non-planar reflective ground plane.

4. The solar energy collection antenna of claim 3 , wherein the non-planar reflective ground plane is further configured as a V-shaped reflective ground plane.

5. The solar energy collection antenna of claim 3 , wherein the non-planar reflective ground plane is further configured as a U-shaped reflective ground plane.

6. A solar powered antenna, comprising:
a reflective suspended plate antenna (SPA) element configured to augment reflected solar radiation associated with a reflective ground plane;
at least one solar cell, proximate to and associated with the SPA element, configured to convert at least a portion of the reflected solar radiation to an electrical potential; and
circuitry adapted to electrically couple the at least one solar cell to the antenna to employ at least a portion of the electrical potential in operation of the antenna.

7. The solar energy collection system of claim 6 , wherein the reflective ground plane is further configured as a non-planar reflective ground plane.

8. The solar energy collection system of claim 7 , wherein the non-planar reflective ground plane comprises a V-shaped reflective ground plane.

9. The solar energy collection system of claim 7 , wherein the non-planar reflective ground plane comprises a U-shaped reflective ground plane.

10. A method, comprising:
augmenting reflection of incident solar radiation at an antenna by at least one reflective suspended plate antenna (SPA) element of an antenna to create augmented reflected solar radiation;
collecting at least a portion of the augmented reflected solar radiation by at least one solar cell proximate to the antenna to create collected solar radiation; and
converting at least a portion of the collected solar radiation into an electrical potential for use by the antenna.

11. The method of claim 10 , further comprising:
using at least a portion of the electrical potential to operate at least a portion of the antenna.

12. The method of claim 11 , wherein the augmenting comprises reflecting at least a portion of incident solar radiation coincident with reflecting a subset of incident solar radiation by a non-planar reflective ground plane of the antenna.

13. The method of claim 12 , wherein the reflecting the subset of incident solar radiation by the non-planar reflective ground plane comprises reflecting the subset of incident solar radiation by at least one of a V-shaped reflective ground plane or a U-shaped reflective ground plane.

14. An apparatus, comprising:
a suspended plate antenna (SPA) element configured to reflect at least a portion of incident solar radiation in conjunction with a subset of incident solar radiation reflected by a reflective ground plane to at least one solar cell.

15. The apparatus of claim 14 , wherein the SPA element is configured to receive excitation via an L-probe proximate to the reflective ground plane.

16. The apparatus of claim 14 , wherein the reflective ground plane is configured as a non-planar reflective ground plane.

17. The apparatus of claim 16 , wherein the non-planar reflective ground plane comprises at least one of a V-shaped reflective ground plane or a U-shaped reflective ground plane.

18. The apparatus of claim 14 , wherein the at least one solar cell is configured to convert at least a fraction of the incident solar radiation into an electrical potential.

19. The apparatus of claim 18 , further comprising:
circuitry electrically coupled to the at least one solar cell to facilitate employing at least a portion of the electrical potential.
