Claim:
1. A radio frequency coupling structure for coupling a radio frequency signal between a first side of the radio frequency coupling structure and a second side of the radio frequency coupling structure, the second side being opposite to the first side, the radio frequency coupling structure comprising: a dielectric layer arranged between the first side and the second side, a first electrically conductive layer arranged on the dielectric layer at the first side, a second electrically conductive layer arranged on the dielectric layer at the second side, an integrated waveguide structure being formed by an array of electrically conductive vias extending through the dielectric layer from the first electrically conductive layer to the second electrically conductive layer and enclosing a portion of the dielectric layer to form an integrated waveguide structure; the first electrically conductive layer comprising a first transition structure, the second electrically conductive layer comprising a second transition structure, the first transition structure and the second transition structure being arranged to electrically couple the radio frequency signal to the integrated waveguide structure and the portion of the dielectric layer being arranged to guide the radio frequency signal between first transition structure and the second transition structure.
