چکیده
|
This paper presents dual-band bandpass filter using defected microstrip structure (dms). the two dmss was integrated with short circuit stub bandpass filter to produce high attenuation and good selectivity between dual-bandpass. the dms was designed at 3 ghz with a fractional bandwidth of about 20% and the attenuation is better than 70 db. the group delay in the passband of dual-band was lower than 1.2 and 1.5 ns respectively. the design was simulated and fabricated on a roger duroid ro4350 with a thickness of 0.508 mm and dielectric constant,er of 3.48. this type of filter is useful in any rf/microwave communication systems to enabling pre-selection of more than one band from interferers. while maintaining its excellent performance,the overall physical and cost reduction can also be achieved using this technique.
