METHOD FOR MATCHING ANTENNA-FEEDER MICROWAVE DEVICES IN THE FEEDER PATH Russian patent published in 2023 - IPC H03H7/38 

FIELD: microwave technology.

SUBSTANCE: for this, a method for matching antenna-feeder microwave devices in the feeder path is proposed, which consists in the fact that at certain points, where the active part of the complex conductivity is equal to the wave conductivity of the line, and the reactive part of the complex conductivity has an inductive nature, equivalent loops are connected parallel to the microstrip line in a non-contact way in the form of rotating discs made of foil dielectric with one-sided metallization, having a lumped variable capacitance. Rotation of the disk provides matching, which is achieved when the compensating conductivity of the capacitive nature of the equivalent loop and the compensated conductivity of the inductive nature of the microstrip line are equal.

EFFECT: high degree of coordination of antenna-feeder microwave devices while ensuring high reliability and manufacturability of connecting a loop to a microstrip line.
