Abstract
This disclosure relates to directional couplers and methods of tuning directional couplers formed in a printed circuit board. The directional couplers include a main line for transmitting power and at least one secondary line having a coupling portion arranged parallel and at a distance from the main line in a coupling region. The directional coupler includes one or more additional coupling lines that have a coupling portion that runs parallel to and at a distance from the coupling section of the at least one secondary line. The one or more additional coupling lines have a connection arranged on the outer portion of the printed circuit board for selective grounding or connection to an external connection.
