Abstract

The present invention comprises an antenna coupling arrangement for connecting a portable communication device to a further signal transmission line. The portable communication device has an external radiative antenna. The coupling arrangement comprises a housing of generally rectilinear configuration having left and right sides, a lower side and a back side arranged to enclose a portable communication device. An antenna coupler is hingedly supported on the housing to pivotably mate with the external antenna of a portable communication device enclosed within the housing. The antenna coupler is connected to a transmission line for further connection to a further antenna or transmission line.

Claims

1. An antenna coupling arrangement for connecting a portable communication device to a further signal transmission line, said portable communication device having an external radiative antenna, said coupling arrangement comprising:

a housing of generally rectilinear configuration having left and right sides, a lower side and a back side arranged to enclose said portable communication device; and

an antenna coupler hingedly supported on said housing to pivotably mate with said external antenna of said portable communication device enclosed within said housing, said antenna coupler connected to a transmission line for further connection to a further antenna or transmission line.

2. The antenna coupling arrangement as recited in claim 1, wherein said antenna coupler comprises an elongated arm having a loop antenna on a distal end thereof which mates circumferentially about said external antenna of said portable communication device for inductive coupling therebetween.

3. The antenna coupling arrangement as recited in claim 1, wherein said antenna coupler comprises an elongated arm having a plate antenna on a distal end thereof in parallel alignment with said external antenna of said portable communication device for capacitive coupling therebetween.

4. The antenna coupling arrangement as recited in claim 3, wherein said plate antenna is of generally U-shape to at least partially enclose said external antenna of said portable communication device.

5. The antenna coupling arrangement as recited in claim 3, wherein said elongated arm is resilient to permit slight bending thereof.

6. The antenna coupling arrangement as recited in claim 3, wherein said elongated arm has a second end with an extended tab thereon to permit manual pivoting of said elongated arm away from said external antenna on said portable communication device in said housing.

7. The antenna coupling arrangement as recited in claim 1, wherein said antenna coupler comprises an elongated arm having an optical photo coupler on a distal end thereof, in optical communication with said external antenna of said portable communication device for optical coupling therebetween.

8. The antenna coupling arrangement as recited in claim 1, wherein said housing is resilient to permit slight bending thereof, and proper introduction of a cellular device therein.

9. The antenna coupling arrangement as recited in claim 1, wherein said antenna coupler has a rubberized sheath thereon.

10. The antenna coupling arrangement as recited in claim 1, including a biasing member arranged within said housing to press against a portable communication device for secure enclosure within said housing.

11. The antenna coupling arrangement as recited in claim 1, including a lip arranged across said lower side of said housing, to facilitate securement of said portable communication device in said housing.

12. A method of coupling a portable communication device having an external radiative antenna, with a further transmission line, comprising the steps of:

providing a housing having a plurality of enclosure side and bottom walls;

placing said communication device in said housing;

attaching an antenna coupler on an upper end of said housing, said antenna coupler connected to said further transmission line; and

pivoting said antenna coupler on said upper end of said housing into communicative alignment with said external antenna of said communication device.

13. The method of coupling a portable communication device with a further transmission line as recited in claim 12, including the step of:

placing a loop antenna on the distal end of said antenna coupler to permit said loop antenna to surround said external antenna of said communication device for inductive rf communication therebetween.

14. The method of coupling a portable communication device to a further transmission line as recited in claim 12, including the step of:

placing a plate antenna on the distal end of said antenna coupler to permit said plate antenna to be in a spaced apart capacitive rf coupling relationship with said external antenna of said communication device.

15. The method of coupling a portable communication device to a further transmission line as recited in claim 12, including the step of:

placing a photo coupler on the distal end of said antenna coupler to permit said photo coupler to be in swingable alignment and in optical communication with said external antenna of said communication device.

16. The method of coupling a portable communication device to a further transmission line as recited in claim 12, including the step of:

biasing said antenna coupler into communicative alignment with said antenna of said communication device by a spring member arranged between said antenna coupler and said housing.

17. The method of coupling a portable communication device to a further transmission line as recited in claim 12, including the step of:

biasing said communication device within said housing into a position adjacent said coupler, by a pressure member arranged in said housing against said communication device.
