PROBLEM TO BE SOLVED: To reduce power consumption in a resistance pattern in an unequal power divider/combiner by a transmission line, such as a microstrip line form formed in a heterogeneous medium. SOLUTION: In the unequal power divider/combiner in the microstrip line form with the connection section between the input line pattern and the plurality of impedance transformer patterns as a branch section, a ground conductor pattern is formed on one surface of a dielectric substrate; and an input line pattern, a plurality of output line patterns, a plurality of impedance transformer patterns, and the resistance pattern are formed on the other surface of the dielectric substrate. In the plurality of impedance transformer patterns, each one end is connected to one end of the input line pattern, and the other end is connected to each output line pattern for arrangement in parallel. The resistance pattern is connected while acting as a bridge between adjacent impedance transformer patterns. A parallel capacity is provided at least in the impedance transformer pattern whose width is the narrowest in the plurality of impedance transformer patterns. COPYRIGHT: (C)2006,JPO&NCIPI
