DIRECTIONAL 3D COUPLER ON MAGNETOSTATIC WAVES Russian patent published in 2020 - IPC H01P5/18 

FIELD: radio equipment.

SUBSTANCE: invention relates to microwave radio engineering, particularly to devices on magnetostatic waves, and can be used as a frequency-selective power coupler. Technical problem of the invention consists in creating 3D microwave power coupler, which enables vertical transmission of signals in multilayer devices with a controlled transmission coefficient, including in integral magnon circuits. Directional coupler on magnetostatic waves, comprising main microwave guide from iron-yttrium garnet film arranged on gallium-gadolinium pomegranate substrate, microstrip antenna for magnetostatic waves excitation, located on one of the end ends of the iron-yttrium garnet film of the main microwave guide, according to the invention, it contains additional microwave guides, each of which is made in form of a film of iron-yttrium garnet, placed on a substrate of gallium-gadolinium garnet, and also comprises microstrip antennas for receiving magnetostatic waves, wherein additional mudguide guides are placed on the main microwave guide perpendicular to its surface, and each of the antennas for receiving magnetostatic waves is located on the end of each film of iron-yttrium garnet additional microwave guides. Width of iron-yttrium garnet film of additional microwaves is from 50 to 500 mcm, film thickness is from 1 to 10 mcm, and distance (gap) between additional microwave guides is from 10 to 50 mcm, length of film of iron-yttrium garnet of main microwave guide is from 100 up to 500 mcm.

EFFECT: technical result consists in the possibility of adjusting the propagation characteristics of magnetostatic waves in a wide frequency range in a multiport mode.
