Common communications device
First Claim
1. A common communications device comprising:
- an array of near-field coupled resonant elements comprising first and second layers of resonant elements, the resonant elements each comprising a loop portion,the device being provided in combination with a data transmission unit and a data reception unit, each of the data transmission unit and the data reception unit having a respective coupling portion, the units being arranged to communicate with one another by means of the coupling portion of each unit and the array of near-field coupled elements,the coupling portion of the data transmission unit comprising a resonant element comprising a loop portion arranged to be near-field coupled to the loop portion of a first resonant element of the array when the data transmission unit is on a first side of the device, the coupling portion of the data reception unit comprising a resonant element comprising a loop portion arranged to be near-field coupled to the loop portion of a second resonant element of the array not being the first resonant element when the data reception unit is on the first side of the device.

11. A common communications device comprising first and second layers of arrays of near-field coupled resonant elements, the resonant elements each comprising a loop portion, wherein the resonant elements of the first array are arranged to be near field coupled to the resonant elements of the second array,
wherein resonant elements of the first layer of resonant elements have a different resonant frequency to resonant elements of the second layer of resonant elements.
