PURPOSE:To attain the movement of a combined point without changing a circuit pattern by changing the position of a conductor wire or the like of a microstrip line. CONSTITUTION:Conductors 10, 10 of the microstrip line are short-circuited by a wire 14, and since a wave entered in the state of in-phase mutually from the microstrip lines B, C having a characteristic impedance Z0 is propagated in a combined line 13 in an even number mode, the wave is outputted to the microstrip line A having a characteristic impedance 2Z0 without the effect of the wire 14 and in the matched state. On the other hand, the wave entered in opposite phase from the lines B, C is propagated in the line 13 in an even number mode, short-circuited at the position of the wire 14 and reflected. Thus, the phase of reflected wave in opposite phase component is adjusted easily without giving effect on the in-phase component by changing the position of the wire 14. |
