Abstract

The present invention comprises a docking system for connecting a portable communication device to a further signal transmission line. The docking system may be arranged within a workstation such as a desk or a tray. The system may also envelope a room in a building or be located in a vehicle, to control and restrict the radiative emission from the communication device and to direct such radiation to a further remote antenna and or signal distribution system connected to the transmission line.

Claims

1. A method of arranging an externally radiative antenna of a personal communication device with a coupling plate in a housing for the purpose of forming a capacitive radio frequency communicative connection therebetween, comprising the steps of:

placing said radiative antenna of said communication device into a parallel, spaced apart and externally offset relationship with respect to said coupling plate disposed in said housing, said coupling plate arranged for securement in said housing, said coupling plate also connected to a signal transmission line; and

radiating radio frequency energy between said externally radiative antenna of said communication device and said coupling plate to effect such capacitive communication.

2. The method as recited in claim 1, including the step of:

operating said personal communication device at a frequency of at least about 860 MHz or higher.

3. The method as recited in claim 1, including the step of:

fixedly arranging said coupling plate in an article of furniture.

4. The system as recited in claim 1, including the step of:

connecting said signal transmission line to a further antenna.
