BROADBAND MICROSTRIP MATCHED LOAD Russian patent published in 2015 - IPC H01P1/26 

FIELD: radio engineering, communication.

SUBSTANCE: microstrip matched load, consisting of series-connected sections of a microstrip transmission line, comprises at least seven alternating sections of a microstrip transmission line with different surface resistance, the outermost of which are sections with low surface resistance, and at least two pairs of open open-circuit stubs, arranged symmetrically at different sides of the microstrip line, each being in the form of two series-connected sections of a microstrip transmission line with high and low surface resistance. Absorption properties of the matched load are determined by a set of both absorption properties of sections of the microstrip line and stubs with high surface resistance and the topology of the structure. The number of sections of strip lines, the topology thereof and electrical parameters are selected such that, in a selected frequency range, the values of standing wave and transmission coefficients are less than given values.

EFFECT: wider frequency band and smaller longitudinal dimensions of the matched load.
