Abstract :
A new hybrid-integrated dual-band filter is proposed for WLAN application, where the lower passband is implemented by a pair of stepped-impedance resonators (SIRs) and the higher passband is provided by two substrate integrated waveguide (SIW) cavities. In our design, the SIRs are embedded into the SIWs to reduce the size. The relationship between the parasitic resonances of SIW structure and the locations of its transmission zeros is studied. Its good performances have been demonstrated by the simulated and measured S-parameters.
