Analytical Design and Simulation of a New Rat-Race Power Divider Using Cross-Talk and Defected Microstrip Structure

Analytical design and simulation of a new 1 to 3 rat-race power divider is presented. Cross-talk between coupled lines and defected microstrip structures are used in this analysis and design. This rat-race is designed for 1.3GHz and divides power equally in 2 ports and isolates last port. Best features of the proposed method are high compacting ability, suppressing high order harmonics, and simultaneously increasing the bandwidth in comparison with conventional rat-races.
