Description

[Brief explanation of drawings]

Fig. 1 is a schematic configuration diagram showing the shape of the inner conductor of the suspended directional coupler of this invention, Fig. 2 is a cross-sectional view of A-A2 in Fig. 1, and Fig. 3 shows the shape of the inner conductor of the conventional coupler. The schematic configuration diagram shown in FIG. 4 is a sectional view taken along line A-N in FIG. 3. Law LBT 2a, 2b...Strip conductor of suspended line, 3...Dielectric substrate. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A directional coupler in which first and second suspended lines each having a pair of strip conductors provided on both sides of a dielectric substrate as inner conductors are arranged close to each other and parallel to each other by a predetermined length on the same substrate. The width of the strip conductor provided on the front surface of the dielectric substrate of the first suspended line is wider than the width of the strip conductor provided on the back surface, and the strip conductor provided on the back surface of the dielectric substrate of the second suspended line. The width of the first and second strip conductors is wider than the width of the strip conductor provided on the surface to form an unbalanced line, and the wide surfaces of the first and second strip conductors having the wider width are arranged so as to face each other. A suspended line type directional coupler.
