Abstract (en)
The invention relates to a directional coupler, comprising: a first conductor; an insulator surrounding said first conductor having an outer surface; a second conductor surrounding said insulator, the first and the second conductor being adapted for power RF (radio-frequency) transmission; a cavity in said second conductor extending to at least the outer surface of the insulator; a third conductor in a mounting position in the interior of said cavity having a portion substantially parallel to the first conductor and end portions substantially perpendicular to the first conductor, the third conductor being arranged for receiving a portion of said power RF transmission; and, a filling element, for filling at least part of the cavity, permanently holding the third conductor in said mounting position.
