In this letter, new two-way and four-way power dividers are proposed using quarter-wave long multi-conductor coupled lines. The design equations for a two-way power divider are derived by analyzing a three-conductor coupled line. Then, the structure is extended to propose a planar four-way power divider with compact size. The fabricated two-way and four-way power dividers at 2.0 GHz show an excellent performance in the insertion loss, impedance matching at all ports and isolation between output ports.
