Patent ID: 7379503

Claim:
A device for receiving digital signals, comprising: a receiving antenna for receiving signals in a near field of a transmitter conductor array, said signals having analog properties; a signal-processing unit for processing signals supplied by the receiving antenna; a digitizer for converting processed signals supplied by the signal processing unit to digital signals; wherein at least one controller is provided for controlling a coupling between said receiving antenna and said transmitter conductor array; wherein a measuring means is provided for determining at least one parameter of relevance to signal quality and is connected to communicate to said at least one controller the determined at least one parameter of relevance to signal quality; and wherein said at least one controller controls the coupling between said receiving antenna and said transmitter conductor array according to the determined at least one parameter communicated by said measuring means; and wherein dielectric or ferromagnetic materials are provided for insertion by means of suitable actuators into a space between said receiving antenna and said transmitter conductor array according to the determined at least one parameter communicated by said measuring means.
