In this study, a multi-section and unequal power division Wilkinson power divider design has been proposed. Euler impedance matching technique has been applied on the output branches of the power division circuit which operating in ultra-wide band. The characteristic impedance of each transmission line section in each way of the circuit selected as the power division ratio of 2:1 has been calculated with Euler polynomials. The input and output impedances of these unequal ways have been determined analytically by microwave calculations. Then, N = 3 layer unequal WPD circuit has been designed by applying Euler approach to all these branches. The center frequency of the proposed Euler applied WPD has been chosen as 2.45 GHz. The bandwidth is between BW=0.64-4.05 GHz. Fractional bandwidth has been realized as 139%. In the power division circuit implemented in the ADS simulation program, 30.4% of the power from the second way and 63.1% from the third way can be transferred
