Substrate Integrated Waveguide Bandstop Filter

Badrul Hisham Ahmad, Ian C Hunter


One new type of filter is presented in this paper. The propose filter is a transmission mode bandstop filter utilizing substrate-integratedwaveguide cavity resonators to provide the required resonance. The bandstop operated at X band frequencies with 450 MHz bandwidth. Stop band is from 8.7 GHz to 9.2 GHz. Insertion loss achieved is less than 0.5 dB and return loss of more than 15 dB. 3D simulator was used to model the structure and simulation results showed very good response. To date, this is the first time such bandstop substrate-integratedwaveguide filter has been reported
