Power divider

Abstract

In cases where a power divider is constructed by using a multilayer substrate, a power divider is obtained which is smaller in size and has a good reflection property. The power divider according to the present invention is provided with a multilayer dielectric substrate (1), strip conductor patterns (2a through 2c) formed on one surface of the multilayer dielectric substrate (1), and a ground conductor pattern (3) formed on the other surface of the multilayer dielectric substrate (1), wherein a transmission line is composed of the dielectric substrate (1), the strip conductor patterns (2a through 2c) and the ground conductor pattern (3), and the transmission line has its one end branched to form a plurality of branch lines (12a, 12b), with an isolation resistance (4) being formed between the branch lines. A first capacitance forming part comprising a first pillar conductor (6a) and a first capacitance forming conductor pattern (5a), both formed in an interior of the dielectric substrate (1), is formed at a branch point (13) of said transmission line.
