Novel design of dual-band unequal Wilkinson power divider with isolation stubs

The design and analysis of a dual-band unequal-split Wilkinson power divider are presented in this paper. A structure consisting of isolation stubs is proposed in order to reduce the parasitic effects between the two stubs that are connected by the isolation resistor. The formulas used to determine the design parameters have been given. Both simulated and measured results of the dual-band Wilkinson power divider are presented to validate our design idea and derived equations.
