A dual-band Wilkinson power divider with microstrip slow-wave structures

In this paper, a quasi Wilkinson power divider operating at two different frequencies and effectively reduce the occupied space to 37.6% by slow-wave structure. Experimental results show that all the features, such as an equal power split, impedance matching at all ports and a good isolation between the two output ports can be fulfilled at two different frequencies simultaneously. The design is validate both by simulation and measurement.
