PROBLEM TO BE SOLVED: To provide a variable distributor capable of arbitrarily changing a distribution ratio while matching impedances. SOLUTION: The variable distributor includes: a branching circuit part (10) for which a main power feed line (12) and first and second branch power feed lines (13, 14) branched from the main power feed line (12) are formed on a dielectric substrate (11); a stab provided so as to be displaced to the first branch power feed line (13), for which a coupling degree to the first branch power feed line (13) is changed by the displacement; and dielectrics (25, 26) provided so as to be displaced to the second branch power feed line (14) or the main power feed line (12), for which an acting area to the second branch power feed line (14) or the main power feed line (12) is changed by the displacement. The matching state of the impedance in the view from the input port of the main power feed line (12) is held by the change of the acting area of the dielectrics (25, 26). COPYRIGHT: (C)2008,JPO&INPIT
