Parametric study of different shapes-slotted substrate integrated waveguide for wideband Applications

18th Mediterranean Microwave Symposium (MMS) -- OCT 31-NOV 02, 2018 -- Istanbul, TURKEYWOS: 000458427500067On the way to design Substrate Integrated Waveguide Bandpass Filter (SIW-BPF) for wideband applications a parametric study of the slot geometry etched on a SIW structure is the preliminary step to design such filter. Three different structures, namely, H-Slotted, T-Slotted, and U-Slotted SIW is investigated in order to examine the effect of altering different geometrical parameter of the unit on its response. H-Slotted Electromagnetic Band Gap (EBG) shows the highest Fractional Band Width (FBW), which is about 90% compared to the others, consequently it could be used to design a wideband SIW-BPF
