あつた。 Generally, directional couplers are used for power monitoring and signal insertion in waveguide systems, but those coupled with cross-shaped coupling holes are widely used because they can be made compact and have good frequency characteristics. It is being On the other hand, when coupling multiple waveguides to a main waveguide,
Multiple directional couplers were connected in cascade along the main waveguide. In this case, there is a disadvantage that the main wave tube is long and large, and particularly in the input circuit of a low-noise amplifier, the longer main wave tube increases the passage loss and deteriorates the noise characteristics.

る。 The directional coupler of the present invention has coupling holes on both sides of the H-plane at one location of the main waveguide, and when the coupling holes on each H-plane are projected onto one H-plane, they are mutually connected to each other. A sub-waveguide is provided on each of the H planes and is provided on orthogonal diagonal lines, and the electromagnetic wave of the main waveguide is coupled to the two sub-waveguides through these coupling holes.

In other words, by configuring the sub waveguides 2 and 3 coupled to the upper and lower H planes of the same point on the transmission path of the main waveguide 1, it is possible to connect two directional couplers with the same length as in the case of one directional coupler. A sexual combiner can be constructed.

良好な方合性結合器を構成できる。 Figure 2 shows the sub-waveguides 2 of each directional coupling part in Figure 1.
It is a top view when it is removed. That is, the coupling hole 4 for the sub-waveguide 2 and the coupling hole 5 for the sub-waveguide 3 are provided so as to be located on diagonal lines that do not overlap with each other. By providing the coupling holes 4 and 5 in this manner, mutual interference between the two sub-waveguides can be prevented and a good directional coupler can be constructed.

特徴をもつている。 As mentioned above, by configuring two directional couplers in one unit, which are integrated by coupling sub-waveguides to both the upper and lower sides of the H plane at the same point on the transmission path of the main waveguide, the main waveguide can be The length of the tube can be shortened. Also,
This structure has the feature that two sub-waveguides do not recombine through the main waveguide, compared to a conventional structure in which multiple sub-waveguides are provided along the main waveguide. .
