Abstract :
In this research article an undergraduate student project on Koch fractal curves based branch line couplers design is reported. The new fractal shaped branch-line couplers, operating at 3.0 GHz, using Koch fractal shapes of different iteration orders, have been successfully designed. The designed couplers, all operated at the designed frequency, achieved a maximum 81% size reduction without much change in the operating frequency and its bandwidth.
