Abstract :

An effective method is introduced to overcome the narrow strip width in unequal Wilkinson power divider with high dividing ratio. In the proposed Wilkinson power divider, the separated microstrip lines are replaced by a uniform asymmetrical microstrip coupled lines. To design the power divider, a suitable error function is defined and then minimized which led to the final dimensions of the proposed unequal Wilkinson power divider. A sample of the proposed power divider with 4:1 dividing ration is designed and simulated, which indicate the effectiveness of the proposed power divider and its design method.
