The technique of dual transmission lines is applied to replace quarter wave transformers for a compact Bagley polygon power divider. The developed Bagley polygon power divider not only can be easily fabricated on the planar printed circuit board without a lumped element, but also has the characteristics of compact size and wide bandwidth. For verification, a proposed three‐way microstrip power divider is designed and fabricated at 2.0 GHz. Simulated and measured frequency responses both validate the proposed power divider with dual transmission lines. Furthermore, the developed power divider only occupies a 23% circuit size of the conventional one.
