Now, if the circumference of the ring line (14) is selected to be 1.5 wavelengths at the center frequency f0, the wave incident from the input terminal (7) is bisected at the point Q3, and the clockwise and counterclockwise directions are respectively obtained. The two waves are added in phase at points Q2 and Q4 and cancel each other out of phase at points Q1 and Q5. Accordingly, an output is obtained at the output terminals (8) and (9), but no output is obtained at the isolation terminals (10) and (11).

First, the distribution operation will be described. Input terminal (7)
At the point Q3, and are added in-phase at the point Q6. Therefore, no current flows at point Q6,
It can be considered an open end. Therefore, it is 1/2 from point Q6.
From points Q2 and Q4, which are separated by wavelength, the admittance at point Q6 is 0, and the と な り wavelength lines (1), (2), (5),
(6) can be considered by removing the opening. The distribution ratio is m
Assuming that n is a pair (where m and n are positive real numbers and m ≠ n), Y3 / Y4 = Y2 / Y5 = m / n from the distribution ratio condition. Also, from the impedance matching condition, Y8 / Y7 = m, Y9 / Y7 = n. Further, Y2 / Y8 = Y10 / Y8 = Y5 / Y9 = Y11 / Y9 = 1 from the condition of the isolation. The above relational expressions are summarized as follows.

Y2=mY7 (1) Y5=nY7 (4) Y8=mY7 (5) Y9=nY7 (6) Y10=mY7 (7) Y11=nY7 (8) ここで点Q3から点Q2をみたアドミタンスYin1,および

Y2 = mY7 (1) Y5 = nY7 (4) Y8 = mY7 (5) Y9 = nY7 (6) Y10 = mY7 (7) Y11 = nY7 (8) Here, the admittance Yin1, which is obtained when the point Q2 is viewed from the point Q3, and the point Q4 is viewed when viewed from the point Q3 The admittance Yin2 is equivalent to connecting the admittance Y8 or Y9 to the end of the quarter-wave transformer of the characteristic admittance Y3 or Y4, respectively.
Yin1 = Y3 2 / Y8, the Yin2 = Y4 2 / Y9. Therefore, (2)
From the equations (3), (5) and (6), the following equation is obtained: Yin1 = {m / (m + n)} Y7 (9) Yin2 = {n / (m + n)} Y7 (10) ( Equations (9) and (10) show that the wave incident from the input terminal (7) is distributed to the output terminals (8) and (9) in the same phase, m: n, and that the impedance of the input terminal is also matched.

Next, the fact that the isolation between the output terminals (8) and (9) is ensured will be described. In this explanation, the operation is divided into an even mode operation in which a wave is incident on the output terminals (8) and (9) in the same phase, and an odd mode operation in which a wave is incident on the output terminals (8) and (9). I will think together.

First, the operation in the even mode will be described. In the case of even mode, for the same reason as described for the distribution operation, 1/4
The wavelength lines (1), (2), (5), and (6) can be considered with open removal. At this time, the output terminal (8),
The impedance matching of (9) is also achieved.

Next, the operation in the odd mode will be described. In the odd mode, the waves enter the output terminals (8) and (9) in opposite phases, so that at points Q3 and Q6, the waves cancel each other out of phase.
The voltage becomes 0. Therefore, point Q that is 1/4 wavelength away from point Q3
From the points 2 and Q4, the admittance as seen from the point Q3, and from the points Q1 and Q5 which are 1 wavelength away from the point Q6, the admittance as seen from the point Q6 becomes zero. Therefore, the quarter-wavelength lines (1), (3), (4), and (6) can be considered as being opened and removed. At this time, the 1/4 wavelength line (2), output terminal (8), and isolation terminal (1
The characteristic admittance of 0) is mY7, 1/4 wavelength line (5), the output terminal (9), and the characteristic admittance of the isolation terminal (11) is nY7. It can be seen that matching has been achieved.

When the even mode operation and the odd mode operation are superimposed,
Waves incident on one output terminal are added in phase and waves incident on the other output terminal cancel each other out of phase. Therefore, when a wave is incident on one output terminal, a wave is applied on the other output terminal. Does not appear, indicating that isolation between the output terminals (8) and (9) has been achieved. At this time, the impedance of the output terminal is matched.

FIG. 2 shows a calculation example of the characteristics when m = 1.33 and n = 0.67. In the figure, (7) to (13) are the same as those shown in FIG. (14) and (15) are output terminals (8),
This is a 1/4 wavelength transformer that matches the line of (9) with the characteristic admittance Y7. (16) and (17) are the output terminals of the quarter-wave transformer. From the figure, it can be seen that good characteristics with no frequency dependence of the distribution characteristics are obtained with an input VSWR of 1.08 or less and an isolation between output terminals of -40.0 dB or less at a fractional bandwidth of 10%.
