Abstract
A high frequency yttrium iron garnet oscillator is described that comprises a coplanar yttrium iron garnet resonator. The coplanar yttrium iron garnet resonator has an yttrium iron garnet sphere, a coplanar coupling structure and a coplanar waveguide. The coplanar coupling structure is integrated with the coplanar waveguide. The coplanar coupling structure is coupled to the yttrium iron garnet sphere. Further, a method of manufacturing a high frequency yttrium iron garnet oscillator is described.

A high frequency yttrium iron garnet oscillator with a coplanar yttrium iron garnet resonator, wherein the coplanar yttrium iron garnet resonator comprises an yttrium iron garnet sphere, a coplanar coupling structure and a coplanar waveguide, wherein the coplanar coupling structure is integrated with the coplanar waveguide, wherein the coplanar coupling structure and the coplanar waveguide are provided in the same plane, and wherein the coplanar coupling structure is coupled to the yttrium iron garnet sphere.
A method of manufacturing a high frequency yttrium iron garnet oscillator, comprising:
- providing a substrate;
- applying a coplanar coupling structure on at least a portion of the first surface of the substrate by using thin-film techniques;
- applying a coplanar waveguide on parts of the first surface of the substrate;
- and
- placing an yttrium iron garnet sphere in proximity of the coplanar coupling structure so that an electromagnetic coupling between the yttrium iron garnet sphere and the coplanar coupling structure is obtained.
A high frequency yttrium iron garnet oscillator with a coplanar yttrium iron garnet resonator, wherein the coplanar yttrium iron garnet resonator comprises an yttrium iron garnet sphere, a coplanar coupling structure and a coplanar waveguide, wherein the coplanar coupling structure is integrated with the coplanar waveguide, and wherein the coplanar coupling structure is coupled to the yttrium iron garnet sphere, wherein the coplanar yttrium iron garnet resonator has a recess portion that is assigned to the coplanar coupling structure, and wherein the recess portion has two recess areas that merge into each other, wherein a first recess area is assigned to the coplanar coupling structure and/or wherein a second recess area is assigned to the coplanar waveguide.
