An effective method is introduced to overcome the narrow strip width in unequal Wilkinson power divider with high dividing ratio. In the proposed method, the separated microstrip lines of the Wilkinson power divider are replaced by a uniform asymmetrical microstrip coupled lines. It is shown that in the proposed method, the width of the narrow microstrip line is significantly wider in comparison to the narrow microstrip line in the conventional Wilkinson power divider with the same

A sample of the designed power divider with 4 : 1 dividing ratio is fabricated and tested, which indicate the effectiveness of the proposed method.
