In this Letter, a new dual-band filtering power divider (FPD) with high isolation and high frequency selectivity by using self-packaged substrate integrated suspended line (SISL) technology has been developed. Both passbands of the proposed FPD can be designed and controlled individually. A pair of transmission zeros at either passband which are due to the multiple coupling paths with electric/magnetic couplings have been realised. The dual-band FPD has been fabricated layer by layer and then assembled, and the design has been demonstrated by experiment. The self-packaged SISL dual-band FPD has a circuit size of 0.41λg × 0.25λg.
