Claim:
1. A power combiner, comprising: a main body having a coaxial structure composed of an outer conductor and an inner conductor; a plurality of power introduction ports installed in a lateral side of the outer conductor and configured to introduce electromagnetic wave powers supplied through power supply lines into the main body; a power combining antenna configured to radiate electromagnetic waves which are supplied through the plurality of power introduction ports via the power supply lines, to a space between the outer conductor and the inner conductor of the main body such that the powers are combined; and an output port through which the combined electromagnetic wave is outputted from the main body, wherein the power combining antenna includes: a plurality of antenna members, each of which has a first pole to which the electromagnetic waves are supplied from the power supply line in each of the plurality of power introduction ports and a second pole that is in contact with the inner conductor; and a reflection part installed in a ring shape along an outer side of the inner conductor from both sides of each of the plurality of antenna members and configured to reflect the electromagnetic waves, wherein a standing wave is formed by the electromagnetic waves incident onto the plurality of antenna members and the electromagnetic waves reflected at the reflection part, and the electromagnetic wave powers are combined by a linked behavior between an induced magnetic field and an induced electric field, which are generated inside the main body by the standing wave so that the combined power propagates through the interior of the main body, followed by being outputted through the output port.
