Abstract

PURPOSE:To divide electric power with good characteristics and small and light construction, by setting the shape of coupling section to be propagated to TE30 mode and using the mutual interference of each mode of TE10-TE30. CONSTITUTION:The sectional shape of the coupling section 6 is taken as the ridge waveguide, and the first and the second rectangular waveguides 10, 11 are coupled with the coupling hole 5. Taking the phase constant of the modes TE10, TE20, TE30 as beta10, beta20, beta30, and the length of the hole 5 as (l), and when (l) is set to satisfy the relation of (beta10-beta30)l=2pi, input signal is output to the terminals 3, 4 with nonreflection at the branch of the output side. Further, taking the output power at the terminals 3, 4 as P2, P4, and the input power at the terminal 1 as P1, then the relation of P3=P1cos<2>(beta20-beta30)lP4=P1cos<2>(beta20-beta30) l. Since (beta20-beta30) is in creased in proportion to the height of the hole 5, the power can be divided variably. Thus, without degrading the reflection and directive characteristics, the power can be divided excellently.
