Abstract
According to one embodiment, a power divider includes a first transmission line, a first input transmission line, a second input transmission line, and the plurality of output transmission lines. The first transmission line has a closed structure. The first input transmission line and the second input transmission line are connected to the first transmission line at locations away from each other along the first transmission line by approximately a quarter of a length of the first transmission line. The plurality of output transmission lines are connected to the first transmission line at locations dividing the length of the first transmission line substantially evenly.
