DUAL-BAND SIW FILTER Introduction  Filters essential components in wireless systems  Substrate integrated waveguides (SIW) enable compact, low-cost filters  Dual-band filters needed for systems operating at multiple frequencies Proposed Design  SIW cavity resonator with two passbands  Curved comb-shaped slots etched on top metallic layer  Slots of different lengths for respective passband frequencies Results  Narrow passbands at 3.6 GHz and 7.8 GHz  Bandwidths of 390 MHz and 690 MHz respectively  High selectivity between passbands  Low insertion loss < 0.5 dB in both bands Conclusion  Dual-band filter with compact size and high performance  Narrow passbands with good selectivity  Etched slots key for achieving dual-band response Key Highlights  SIW enables low-cost, integrated filter implementation  Curved comb-shaped slots generate dual resonant modes  Excellent selectivity and low loss achieved  Compact dual-band filter suitable for wireless systems
