Abstract :
Propose a novel substrate integrated waveguide (SIW) dual mode filter with circular cavity. The configuration and the measured results show that its 3 dB bandwidth is 24.36 GHz to 25.59 GHz (1.23 GHz) with 1.71 dB insertion loss. Its stop band is from 26.00 to 31.57 GHz with rejection over 40 dB.
