ABSTRACT:
A directional coupler formed as a strip line which consists of two transmission lines coupled to each other and formed on opposite surfaces of a dielectric carrier plate with one of the lines comprising a microstrip line. A directional coupler is formed which has very high sharpness of directivity and high coupling attenuation, and great electrical strength. The second transmission line is formed as a coplanar line which includes a strip line which is mounted on the grounded side of the microstrip line in an area which is free of the grounded line surface and which extends essentially parallel and has current which is opposite to the strip line of the microstrip line. The invention is particularly adaptable for use where a directional coupler having high coupling attenuation is required, as, for example, in VSWR monitoring in secondary radar devices.
