1. A coupling device for coupling microwave radiation from a first microwave structure into a second microwave structure, wherein the first and second microwave structures share a common wall with an iris opening, the device comprising: N electrically conducting conductor loops positioned in front of the iris opening on the side of the first microwave structure, with N≥3, the conductor loops being arranged coaxially in an array along a z-axis, with axially neighboring conductor loops being separated by a dielectric.
