A wideband power divider for microwave applications

A wideband power divider on single layer microstrip technology is proposed, analyzed and fabricated. The proposed divider is designed by using two-section impedance transformers with an input and two symmetrical output extension lines. The analysis of the power divider is performed by applying transmission line theory. Better return loss and isolation factor is demonstrated over 50% impedance bandwidth by applying -15 dB bandwidth criterion. The prototype of the proposed power divider is fabricated and tested to verify the design and it has been noticed that the simulated results are in agreement with the measured data.
