A Novel Unequal Wilkinson Power Divider for Dual-Band Operation

This paper presents the design of a novel dual-band unequal Wilkinson power divider. The proposed power divider can operate at arbitrary two frequencies without reactive components. To achieve the dual-band operation, four groups of transmission lines called network 1, 2, 3 and 4 are introduced. The design and analysis of power divider are presented. Closed-form design equations are derived based on network theory. The validity of this analysis is confirmed through the design, simulation, and experimental results with a power divider for 1 and 2 GHz.
