The Modular Design of M-SIW Wideband Band-stop Filter

Abstract: The wideband band-stop filter M-SIW (Microstrip-Substrate Integrated Waveguide) is designed to achieve tradeoff between low loss and low cost with simplicity. In this section the high-pass filter of the Substrate Integrated Waveguide (SIW) in a modular system and parts of a Microstrip low-pass filter are combined. The M-SIW band-stop filter was created using a concept design which is simple and straightforward, making it simple to build a band-stop filter at the output frequency with required specification. The experimental determination of the M-SIW wideband band-stop filter that was manufactured was discovered to BW = 5.15 GHz and fC = 4.74 GHz based on a simulation performed by Computer simulation Technology (CST).
