A dual-band Wilkinson power divider with 6:1 power dividing ratio using coupled lines

In this paper, a novel dual-band Wilkinson power divider with 6:1 power dividing ratio is presented. For this purpose, two sections of coupled lines terminated with shorted stub are employed to replace the quarter-wavelength transmission lines in the classical single-band unequal Wilkinson power divider. Based on the evenodd analysis, the design equations are given. As an example, a dual-band Wilkinson power divider with 6:1 power dividing ratio is designed at 1.0 GHz and 1.8 GHz.
