Abstract: A waveguide structure includes a first waveguide section mechanically and electrically connected by a fixed connector to a second waveguide section. The waveguide sections include a dielectric material with a ground layer and a conductor structure with a pair of elongate conductors. The fixed connector includes a dielectric material with a pair of contact pads insulated from a ground layer. The fixed connector is attached by its top side to the bottom sides of interface sections of the waveguides sections forming a ground contact. The interface sections each comprise an intermediate conductor from each of the elongate conductors at the top side to the bottom side of the dielectric material. The intermediate conductors are connected via the contact pads.

Abstract: An inductive component in the form of a balun for use in magnetic resonance imaging tomographs comprises a winding of a coaxial line. For adjusting inductance of the winding, a length of the winding of the coaxial line is deformable. For this, a first end of the coaxial line is fastened to a first fastening block, and a second end to a second fastening block. Change of the length is effected by means of an adjusting screw which varies the distance between the two fastening blocks.
