Dual-band Wilkinson power divider and its miniaturization using coupled line sections

Abstract

In this paper, a generalized two-way dual-band Wilkinson power divider (WPD) with four open-circuited stubs is discussed. A coupled line section is introduced to reduce circuit size based on the assumption of linear phase characteristics. A normal size WPD and its miniaturized WPD were fabricated. Experimental results were in good agreement with predicted ones.
