Patent ID: 8098206

Claim:
A device, comprising: an electric antenna having at least one current-carrying electric conductor; a magnetic antenna having a coil with at least one current-carrying conductor loop which acts as an inductor of the magnetic antenna; a printed circuit board, the electric antenna and the magnetic antenna spatially arranged in immediate mutual proximity on the printed circuit board, the current-carrying electric conductor of the electric antenna extending along the printed circuit board which acts as a resonator, wherein the coil of the magnetic antenna and the current-carrying electric conductor of the electric antenna are arranged in parallel to each other so that an induction of currents in the antennas due to a mutual interference between the antennas is reduced, and a filter arranged between the electric antenna and the magnetic antenna, wherein the filter is in the form of an LC high pass, and wherein the electric antenna further has a first and a second vertical element, the vertical elements and a portion of the current-carrying electric conductor connecting the two vertical elements to each other forming an adapter loop, the adapter loop acting as an inductor of the LC high pass.
