In this paper, a planar three-way power divider with compact size is presented using quarter-wave long five-conductor couple line. It is analytically proved that the proposed structure allows the performance of three-way power dividers. Based on the derived equations and simulation, the three-way power divider is designed and measured at 2.0 GHz. The measurement shows excellent performance with insertion loss of 0.2 dB, and return loss and isolation better than 20 dB at a design frequency.
