Abstract

This study develops a compact microstrip bandpass filter using a modified coupled line structure. By adjusting the coupled line step split ratio, the finite frequency transmission zero can be tuned. The passband produces two transmission zeros. Designing and evaluating the suggested filter makes use of HFSS and ADS. Two prototypes are produced on the Roger Duriod 5880. The fabrication losses are adjusted by post-fabrication tuning. A vector network analyzer is used to do the measurement. The output prototype size is 0.2λg x 0.18λg. The findings of the simulated and measured S-parameters are in good agreement.

Keywords: Bandpass filter, modified coupled-line structure, compact filter design, miniaturized filter, wireless communication, out-of-band rejection, high performance filter.
