LOW-COST C-BAND SIW BANDPASS FILTER USING FR4-EPOXY SUBSTRATE


(Received: 25-Jan.-2023, Revised: 30-Mar.-2023 , Accepted: 17-Apr.-2023)
This paper describes a substrate-integrated waveguide (SIW) filter built on an Fr4-Epoxy substrate with a dielectric constant εr = 4.4 and a height of h = 1.6mm. SIW-based devices have piqued the interest of researchers in recent years due to their low loss, small size and low cost. The goal is to simulate and realize an SIW filter for C-band applications. The designed filter is analyzed using the reflection coefficient S11 and electric field distributions. We used the HFSS simulator. According to the findings, there is a high degree of agreement between the simulated and realized filters. The results also show that the filter has a very good response. It also displays bandwidth around C-band frequencies (6.3GHz). This filter’s pass-band ranges from 5.39 to 6.83GHz, with an insertion loss of 4.2dB and a return loss of 45.49dB.
