Design of substrate integrated waveguide cavity bandpass filters

The paper is presenting two bandpass filters based on the SIW technique design operating in two frequency bands: C and X. The first filter used in C-band has a fractional bandwidth of 3.8 % centered at 6 GHz and insertion loss of 0.9 dB. The second in the frequency band 8-12.5 (X-band) has a fractio...

Description
Summary:The paper is presenting two bandpass filters based on the SIW technique design operating in two frequency bands: C and X. The first filter used in C-band has a fractional bandwidth of 3.8 % centered at 6 GHz and insertion loss of 0.9 dB. The second in the frequency band 8-12.5 (X-band) has a fractional bandwidth 2.7 % centered at the midband frequency 9.27 GHz with insertion loss of 0.84 dB and an out-of-band rejection level of 70 dB.
