A miniaturized three way power divider

A miniaturized three-way Wilkinson power divider that provides equal power split over a wide bandwidth implemented on a single-layer printed circuit board (PCB) is presented. In this work, the bent microstrip line replaces the straight microstrip line of the conventional power divider, thus, the size of the proposed power divider is 44.75 mm times 70 mm, which is much smaller than the conventional proposed power divider. Good experimental performances of the proposed power divider, including an even power split, low loss, and good isolation between the output ports are obtained. Measured results show that VSWR of the input and three output ports is less than 1.6 across the bandwidth from 0.7 to 1.1 GHz.
