Abstract (en)
[origin: EP1054467A1] The method involves encasing the strip conductors in a setting material (VM) whose quantity is selected to achieve a defined coupling factor. The circuit board is arranged in a housing that is filled with sufficient setting material that the required coupling factor is reached. An Independent claim is also included for a strip conductor directional coupler with at least two strip conductors on a circuit board.
