This study presents a compact three-way Bagley Polygon power divider integrated with bandpass response. Two compact filters are embedded into the power divider to replace the conventional quarter-wavelength transmission lines (TLs). Moreover, the zero-degree TLs are utilised to realise the miniaturisation, meanwhile, the power divider's intrinsic isolation performance is maintained. Analysis and guided equations are given. For verification, a Bagley Polygon power divider integrates with good filtering response and wide stopband is fabricated. Good agreement between the prediction and measurement validated the proposed method.
