DEVICE FOR AUTOMATIC MATCHING OF THE IMPEDANCE OF THE ANTENNA-FEEDER PATH WITH A COMPLEX LOAD Russian patent published in 2022 - IPC H03H7/38 G01R27/06 H03J7/02 

FIELD: antenna technology.

SUBSTANCE: invention relates to automatic devices for matching arbitrary impedances of the antenna-feeder path with a complex wave resistance of the load. The automatic matching device contains four directional couplers (DC) connected in series by pass-through channels DC₁, DC₃, DC₄ and DC₂, the output of the latter DC₂ is connected to an amplitude-phase-impedance corrector consisting of three matching links (ML) ML₁, ML₂ and ML₃ connected in the T-shaped manner, a unit for calculating the standing wave coefficient Swc, a unit for calculating the phase of the reflection coefficient, a unit for calculating the active component and a unit for calculating the reactive component of the complex load resistance, a unit for selecting matching links, the active component matching controller and the reactive component matching controller, the central control computer analyzes and determines the operation of the matching device.

EFFECT: providing real-time automatic matching of the impedance of the complex load.
