This paper presents design and fabrication of 2way Wilkinson power divider (WPD) for dual operating frequency. This WPD use dual operating frequencies on 2.4GHz and 4.928GHz. In this WPD, two branches of impedance transformer and the output ports are shunted with parallel connection of a resistor (R), an inductor (L) and a capacitor (C).Simulation and measurement results of this WPD design are shown by the graphs of insertion loss (S21 and S3t>, return loss both of input and output (Sl1, S22 and S33) and also isolation between the output ports (S32). Based on the simulation and measurement results, this WPD have a better insertion loss and isolation, and also produce a better return loss of input and output ports for operating on the both frequencies of2.4GHz and 4.928GHz.
