MICROSTRIP DIPLEXER Russian patent published in 2023 - IPC H01P1/213 

FIELD: microwave equipment.

SUBSTANCE: invention relates to diplexers. A microstrip diplexer contains a dielectric substrate, on one side of which a grounded base is applied, and on the other side strip conductors of the resonators are applied. In this case, the resonators are made half-wave and are connected to each other electromagnetically and conductively due to jumper sections, and the narrow sections of the strip conductors of the resonators are L-shaped and connected to each other by a wide section, while the common input is placed on a wide section of the strip conductor of the central resonator, with the side opposite the free end.

EFFECT: improvement in the frequency-selective properties of the diplexer, expansion of adjacent passbands of low-frequency and high-frequency channels.
