A novel millimeter-wave multilayer dual-mode filter with power divider is developed based on the substrate integrated waveguide circular cavity (SICC). The novel dual-mode SICC filter/power divider with arc-shaped coupling slots has been designed for Ka-band application. The multilayer dual mode filter/power divider has been firstly realized only by adjusting arc-shaped coupling slots located in metal layers. Simulated results show that excellent impedance matching at all three ports, amplitude and phase balance at the two output ports, and out-of-band rejection are observed at the operating band. Meanwhile, it is possible to control the return loss, bandwidth and rejection level by adjusting the size of the coupling slots. This novel filter/power divider is very compact and has the advantages of return loss, very low insertion loss, high selectivity.
