A compact dual-band Wilkinson power divider with two design approaches

Abstract

A compact dual-band Wilkinson power divider with coupled open stubs is newly presented. Coupled open stubs are not only used for miniaturization but also used to get isolation between two output ports. Based on an even- and odd-mode analysis, the proposed model provides two different design approaches. The design charts, coupling coefficients, and bandwidths between two design approaches are discussed and compared under the same conditions. For verification, experimental results are also presented.
