Microwave power divider or power combiner that is coupler are used for effective power transmission in antenna and different electromagnetic circuit design. in this paper we discuss different planner technology and approach for the reduction size of branch line coupler .in detail we describe fractal geometry reduced the are approximately 81.8%.that are used the inner and outer are effectively. for enhancing the bandwidth used the cascaded structure. used centre frequency 2.4 GHz .
Branch line coupler, fractal.
