The use of interdigitated structures allows significantly reducing the dimensions of the topology, which is especially important for the UHF range. The initial stage of the methodology involves obtaining an equivalent coupler circuit in T- or U-shaped sections with concentrated inductive and capacitive elements, including the calculation of their nominal values. At the stage of transition from an electric circuit with lumped elements to a planar topology, the original analytical relation is used to determine the number of sections of the interdigital structure by the value of the lumped capacity. There is a technique for obtaining analytical relations of a similar content for any other, different from the used, geometric and dielectric parameters of the section. At the final stage, local use of the CAD optimization apparatus is assumed. The combination of parametric optimization and ready-made topological solutions can significantly reduce the time for designing microstrip miniature couplers. The technique was tested in relation to the design of a directional coupler with an operating frequency of 0.9 GHz. Whereas the area of the synthesized topology of the double-loop coupler is 30% of the area of the traditional topology with a slight deterioration of the main indicatorsShow less >
