A wideband bandpass filter with high passband selectivity and spurious response suppression is proposed. The filter consists of a pair of open stubs and two cascaded parallel coupled lines (PCL). A novel compact microstrip resonant cell (CMRC) with slow wave characteristic is applied to improve the...
