PURPOSE: To obtain a two-distributer with opposite phase of microwave at low cost by constituting the titled distributer by a microstrip line formed only on one side of a dielectric board and an interdigital line so as to facilitate the manufacture and mount of the board.

CONSTITUTION: An electric field of a microwave signal coupled to an input terminal of a coupling line is an electric field always directing in parallel conductors 42, 44 whose tips are connected to ground from parallel conductors 41, 43 whose tips are opened over the entire line as shown in the arrow. Conductor groups 41, 43 whose ends are connected at every other conductor are connected to an output line 2 at the output ends of the parallel conductors 41∼44 and other groups 42, 44 are connected to an output line 3, then the direction of electric field of the microwave signal in the output lines 2,3 is, as shown in the arrow, is downward from the output line 2 toward the ground conductor 5 in the former group and is upward from the ground conductor 5 toward the output line 3 in the latter group, the direction of the electric field is completely opposite in the output terminals P2, P3 and the two output waves are outputted in the opposite phase. As above, all the circuit pattern of the microwave distributer of the two-distributer of opposite phase is formed by using only one side of the dielectric board 100.
