In this paper, an effective miniaturization technique for a conventional dual-band Wilkinson power divider ispresented. By applying an additional size-reduction approach to a previously reported π-type equivalent dual-bandstructure, the effective circuit core area is significantly reduced while preserving the dual-band operatingcharacteristics. The proposed miniaturized structure is implemented on a cost-effective FR4 substrate instead ofexpensive low-loss substrates, and its validity is experimentally verified at 0.92 GHz in the Sub-GHz IoT band and2.4 GHz in the ISM band.
