Abstract
In an antenna coupler, a multilayer printed-circuit board has conductor levels which are electrically isolated from one another in the depth direction. A first radio-frequency line coupled to the antenna is arranged in a first conductor level, while a second radio-frequency line coupled on the appliance side is arranged in a second conductor level of the board. The board has an electrically insulating core layer, with the first and second conductor levels extending on the same of the two faces of the core layer and with the second radio-frequency line at a greater distance from the core layer than the first radio-frequency line. Furthermore, the second radio-frequency line is arranged on an outer surface of the board. The antenna coupler comprises an electrically conductive shielding structure designed to shield the first radio-frequency line and appliance-side metal parts, which are not part of the antenna coupler, against interaction with radio-frequency signals.
