Abstract

Aspects of the subject disclosure may include, a waveguide device including a coupler that transmits or receives electromagnetic waves that propagate along a transmission medium without requiring an electrical return path, where the electromagnetic waves are guided by the transmission medium. The waveguide device can include a housing that houses the coupler, where the housing has a first portion comprising a material that reflects particular wavelengths of light. Other embodiments are disclosed.

Claims

1. A waveguide device comprising:

a coupler that facilitates transmitting or receiving electromagnetic waves that propagate along a transmission medium without requiring an electrical return path, wherein the electromagnetic waves are guided by the transmission medium; and

a housing that houses the coupler, wherein the housing facilitates coupling the waveguide device to the transmission medium, wherein the housing has a first portion and a second portion, wherein the first portion comprises a material that reflects infrared light, and wherein the second portion does not include the material that reflects the infrared light.

2. The waveguide device of claim 1, wherein the material is a layer on an outer surface of the first portion of the housing, and wherein the electromagnetic waves are microwaves or millimeter waves.

3. The waveguide device of claim 2, wherein the housing comprises a plastic material.

4. The waveguide device of claim 1, wherein the material comprises a dichroic material.

5. The waveguide device of claim 1, wherein the second portion has an outer surface having a black color.

6. The waveguide device of claim 1, wherein the first portion of the housing has a first outer surface having a first color, wherein the second portion of the housing has a second outer surface having a second color, and wherein the second color is darker than the first color.

7. The waveguide device of claim 1, wherein the first portion is an upper portion of the housing that reflects the infrared light from sunlight when the waveguide device is coupled to the transmission medium, and wherein the second portion is a lower portion of the housing.

8. The waveguide device of claim 1, wherein the first and second portions are an entirety of an outer surface of the housing.

9. The waveguide device of claim 1, wherein the housing surrounds the transmission medium when the waveguide device is coupled to the transmission medium.

10. A communication device comprising:

a first waveguide device housed in a first housing, wherein the first waveguide device facilitates transmitting or receiving first electromagnetic waves that propagate along a transmission medium without requiring an electrical return path, wherein the first electromagnetic waves are guided by the transmission medium, wherein the first housing comprises a material that reflects a portion of a light spectrum to reduce heat absorption by the first housing;

a second waveguide device housed in a second housing, wherein the second waveguide device facilitates transmitting or receiving second electromagnetic waves that propagate along the transmission medium without requiring the electrical return path, wherein the second electromagnetic waves are guided by the transmission medium;

a wireless device housed in a third housing; and

a support structure physically connecting the first, second and third housings.

11. The communication device of claim 10, wherein the portion of the light spectrum includes infrared light, wherein the first housing has a first portion and a second portion, wherein the first portion comprises the material that reflects the portion of the light spectrum, and wherein the second portion does not include the material.

12. The communication device of claim 11, wherein the first portion of the first housing has a first outer surface having a first color, wherein the second portion of the first housing has a second outer surface having a second color, and wherein the second color is darker than the first color.

13. The communication device of claim 12, wherein the second housing comprises the material that reflects the portion of the light spectrum.

14. The communication device of claim 13, wherein the second housing has an upper portion and a lower portion, wherein the upper portion comprises the material that reflects the portion of the light spectrum, wherein the lower portion does not include the material, wherein the upper portion of the second housing has an upper outer surface having a first color, wherein the lower portion of the second housing has a lower outer surface having a second color, and wherein the second color of the lower outer surface of the second housing is darker than the first color of the upper outer surface of the second housing.

15. The communication device of claim 11, wherein the third housing comprises the material that reflects the portion of the light spectrum.

16. The communication device of claim 11, wherein the support structure comprises the material that reflects the portion of the light spectrum.

17. A waveguide device comprising:

a coupler that facilitates transmitting or receiving electromagnetic waves that propagate along a transmission medium without requiring an electrical return path, wherein the electromagnetic waves are guided by the transmission medium; and

a housing that houses the coupler, wherein the housing has a first portion comprising a material that reflects particular wavelengths of light.

18. The waveguide device of claim 17, wherein the particular wavelengths of light comprise infrared light, wherein the first portion is an upper portion of the housing that reflects the infrared light from sunlight when the waveguide device is coupled to the transmission medium.
