Design and Performance Evaluation of Wilkinson Power Divider

This paper describes a novel design of Wilkinson power divider at 2.63GHz using a HFSS software for dividing the power equally at both the output port and the phase imbalance between the output port is given as 90 degree phase difference with the help of unequal length of the port 2 with respect to port 3. A quarter wave transformer is proposed in this design of
$\lambda/4$
length. The simulated results show that the return loss and isolation are satisfactory. The 100Ω resistance is required to provide the isolation between the outputs. The substrate of RO3003, dielectric constant 3, loss tangent 0.0013 is used in the simulated design. The results of simulations and measurements describe the implementation of the presented method.
