摘要：

A compact dual-band filtering power divider (FPD) is presented based on substrate-integrated waveguide (SIW) triangular cavities (TCs). By exploiting the first two modes in SIW TCs, the FPD is synthesised and designed with centre frequencies of 5.5 and 8.3 GHz and identical absolute bandwidths of 0.8 GHz. Two-section 50 Omega transmission lines loaded with two resistors are explored to achieve good isolation at two arbitrary frequency bands of the dual-band PFD. Good agreements can be observed between the measured and simulated results and better than 20-dB isolation within the two passbands has been successfully achieved.
