摘要：

A compact multilayer substrate integrated waveguide (SIW) balun bandpass filter is proposed. A 180 degrees reverse phase characteristic between the input/output ports can be easily achieved by the middle metal-ground of the SIW power divider. Four inductive posts are added to the multilayer SIW power divider to realise a passband. Good in-band balance performance (amplitude and phase imbalance are less than 0.35 dB and 2 degrees) over the passband are achieved for the balun bandpass filter.
