摘要：PURPOSE:To obtain a multi-terminal directional coupler capable of dividing the power of an input signal with miniaturization, light weight and excellent electric characteristic by providing a missing part to a ground conductor clipped by dielectric bas and providing plural directional couplers coupling conductors for coupling. CONSTITUTION:Coupling holes 17a, 17b are provided to a prescribed part of a ground conductor t0 thick and coupling dielectrics 10ca, 10cb are packed. The conductor 11 is chipped by the dielectric bas 10a, 10b in the thickness of (t). Each short side of the coupling hole 17a and each short side of coupling conductors 18a, 19a are in contact with two same longitudinal cross ctional faces. Moreover, the bas 10a, 10b and the dielectric 10ca have the same dielectric constant and formed incorporatedly. A directional coupler 9ca having a prescribed coupling degree is constituted of the coupling conductors 18a, 19a and the conductor 11 formed to the bas 10a, 10b. Then the dielectric constant of the bas 10a, 10b, the width of the conductors 18a, 19a and the width of the coupling hole 17a are decided properly to constitute a four-terminal directional coupler 9ca having a coupling degree of 3dB.
