Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. The present invention relates to a technique for implementing, in a compact form, a four-way power divider and combiner for a phased array system. More particularly, according to one embodiment of the present invention, a power divider including one input port and four output ports comprises an input terminal inductor having one end connected to the input port and the other end connected to the ground, an inductor group including four output terminal inductors, and four connection units for connecting the input port and the inductor group, wherein four secondary inductors are respectively connected to the four connection units so that four nodes are formed between the four connection units and the inductor group, and the output ports are respectively disposed on the four connection units between the input port and the inductor group.
