DESIGN OF A MICROSTRIP DUAL-BAND FILTER WITH MODIFIED SHORT-CIRCUIT QUARTER-WAVELENGTH RESONATORS

摘要

A dual-band microstrip bandpass filter is proposed. With the assistance of modified short-circuit quarter-wavelength resonators, the dual-band bandpass filter can be developed. Theoretical analysis and design procedures are provided; the prototypical bandpass filter with dual passbands is fabricated and measured as well. Well-matched simulated results and experimental data validate the proposed filter.
