Abstract:
    The disclosed directional coupler includes medium base plate with metal patches on its two faces. Input end, output end, isolation end and coupling end are setup on one face of the metal patch. Since integration waveguide structure in halfmodule base plate reserves inherent characteristic of low loss and since aspect ratio of the integration waveguide is smaller than SIW, thus, the loss of electromagnetic wave generated in process of transmission caused by nonideal medium is smaller so as to possesses better characteristic of low loss. Using mature technique for fabricating printing circuit board in single layer to produce the structure of waveguide, the invention possesses features of low cost, satisfied precision and performance so that mass production is feasible.
