Abstract :
A modified Wilkinson power divider/combiner using one added stepped- impedance open-circuited radial stub on each branch is proposed for UWB applications. The stepped-impedance open stub is used to introduce multiple transmission poles through the whole UWB frequency spectrum. The simulation results of the proposed small size and low cost power divider have shown equal power split between the two output ports with good insertion loss and satisfactory isolation within the whole UWB frequency range. Also, it has been shown that the designed UWB power divider has good return loss of all ports.
