Abstract: A miniaturized dual-band Wilkinson power divider with a coupled-line section is presented. The output ports are isolated physically to reduce parasitic effects and to make an interconnection with other passive-active devices easy. Closed-form design equations based on an even-and odd-mode method are obtained. The design methods are discussed in details. The measured results of a microstrip power divider operation at 1 GHz and 2 GHz verified the theoretical feasibility of the proposed power divider.

Key words: communication, dual-band, Wilkinson power divider, physical port separation, coupled-line
