Abstract

A universal antenna housing suited for deployment under the glass dome of a utility meter. The housing is fitted with an integrated antenna for wireless radio communications. Applications include the transmission and receiving of radio communication for wireless automatic meter reading (AMR) systems, as well as commercial, industrial or residential utility meters that operate at a plurality of unlicensed or licensed radio frequencies. A configuration and method for economical assembly of an antenna is also disclosed.

Claims

1. An antenna assembly comprising:

a housing comprising;

a dielectric strip formed about a central axis and having a thickness, a face and an end; and

a recess formed on said face of said dielectric strip; and

an antenna disposed in said recess.

2. The antenna assembly of claim 1 further comprising an antenna mounting surface in said recess, said antenna mounting surface being substantially parallel to said face of said dielectric strip;

and wherein said antenna is in contact with said antenna mounting surface.

3. The antenna assembly of claim 2, further comprising a plurality of tabs extending substantially parallel to said face of said dielectric strip, said tabs extending at least partially over said antenna mounting surface, said antenna being captured between said tabs and said antenna mounting surface.

4. The antenna assembly of claim 1 further comprising a single post having a cross-section that cooperates with a mating receptacle on an objective device to key said housing in a specific orientation with respect to said objective device, said cross-section having no more than one lateral axis of symmetry.

5. The antenna assembly of claim 1 further comprising at least one guide hole formed through said thickness of said housing to facilitate mounting of said housing to an objective device.

6. The antenna assembly of claim 1 further comprising a mark that locates where to form a guide hole.

7. The antenna assembly of claim 1 wherein said housing is under glass mounted.

8. The antenna assembly of claim 1 further comprising a utility meter operatively attached to said antenna for automated meter reader wireless communication.

9. The antenna assembly of claim 1 further comprising at least one post to secure said housing to an objective device.

10. The antenna assembly of claim 1, wherein said dielectric strip is formed from a single piece material.

11. The antenna assembly of claim 10, wherein said single piece material is an injection molded material.

12. The antenna assembly of claim 1, wherein said dielectric strip further comprises a portion that defines a radius and having a shape selected from the group consisting of a U-shape, C-shape and lunate, said face of said dielectric strip being normal to said central axis.

13. The antenna assembly of claim 12, wherein said face of said dielectric strip faces inward.

14. The antenna assembly of claim 12, wherein said housing is dimensioned to cooperate with an objective device so that said radius is of greater dimension when mounted on said objective device to exert a restoring force that secures said housing to said objective device.

15. The antenna assembly of claim 12 having at least a first post and a second post, each of said first and second posts depending from said face of said housing and having a base cross-section defined at said face of said housing and wherein said base cross-section of said first post is of a substantially smaller cross-section than said base cross-section of said second post.

16. The antenna assembly of claim 12 wherein said at least one post has a circular cross-section.

17. The antenna assembly of claim 12 wherein said antenna is a flexible antenna.

18. The antenna assembly of claim 17 wherein said flexible antenna is a printed circuit antenna or a stamped metal antenna.

19. A method of mounting an antenna comprising:

selecting an antenna assembly comprising

a housing having a shape about a central axis,

at least one post extending radially inward from said housing, and

an antenna substantially conforming to said shape of said housing;

selecting a mounting surface having a mating receptacle compatible with said at least one post; and

placing said at least one post in said mating receptacle of said mounting surface.

20. A method of fabricating a flexible antenna comprising:

selecting a dielectric substrate having an antenna pattern comprising a first solder pad and a second solder pad, each of said first and second solder pads being located substantially on an axis;

providing a cable comprising a central conductor and a ground shielding, said central conductor protruding substantially linearly from an exposed end of said ground shielding;

aligning said cable substantially parallel with said axis;

placing said central conductor in electrical contact with said first solder pad and attaching said central conductor to said first solder pad; and

placing said exposed end of said ground shielding in electrical contact with said second solder pad and attaching said ground shielding to said second solder pad.
