The circular cavity structure using TM010 mode for filter is reemployed in the design of this bandpass filter. To realize this concept, the magnitude of E-field distribution for SIW filter resonating at TM010 mode is study and analyzed based on the effect of using low permittivity of substrate rogers duroid which is 2.2 and make it air as substrate have a permittivity of 1. The simulation results show a good insertion loss and return loss that prove the concept of low permittivity substrate gives better insertion and return loss. To prove the concept, the SIW filter is fabricated using Rogers Duroid RT5880 with dielectric constant, er =2.2, tangent loss of 0.001, and thickness of 0.787mm. The measured results show good agreement with simulation results. Results show 48.06% improvement (-18.81dB) of return loss (Sn) can be obtained from air as substrate compare with Roger Duroid RT5880 has -9.77dB.
