摘要

The antennas has housing (22) that comprises an antenna coil (14) having windings of insulated copper wire, is provided on a recess (13) at the inner wall (11) of a housing shell (12). The wire ends (19) of the antenna coil on the inner wall of the housing shell are fixed with an electrically conductive adhesive (26). Multiple electrodes (20) are electrically conductively fixed to the wire ends of the antenna coil.
