Abstract

PURPOSE:To establish the directional detector of small size, by locating the ferri- magnetic substance and detection diode magnetized in the external magnet in the waveguide on one surface orthogonal to the wave guide tube axis. CONSTITUTION:In the waveguide 5, the ferri-magnetic substance 7 magnetized with the external magnet 6 and the detection diode 8 are provided on one surface orthogonal to the direction of tube axis of the waveguide 5, and the load resistor 9 is connected to the diode 8 externally. When the microwave input FL is fed to the input opening of the waveguide 5, it is given the rotation toward right at the magnetic substance 7 and it goes toward the output opening. Further, the relection wave FR returned with reflection to the output opening is given the rotation toward right at the magnetic substance 7 and it is not almost returned to the input opening, but absorbed at the diode 8. From the result of experiment, when the distance b between the center of the magnetic substance 7 and the inside wall of the waveguide is taken about 1/3 the length a of the wider side of the waveguide path and the distance c between the diode 8 and the waveguide side wall is set about 1/4 of a, the isolation performance is most excellent.
