DIRECTIONAL COUPLER ABSTRACT OF THE DISCLOSURE A directional coupler comprising a main line (1) and two conductive chips (2a, 3a) which are capacitively coupled to the main line (1) in a lumped constant fashion. The conductive chips (2a, 3a) are separated by a distance of .lambda.g/4. Signals on the conductive chips (2a, 3a) are transferred, through first and second conductive patterns (B1, B2) narrower than the main line, to an output terminal. The first conductive pattern and the second conductive pattern are different in length by .lambda.g/4, and a loose and directional coupling signal is obtained at the output terminal.
