Miniaturized dual-band bandpass filter with closely spaced passbands and wide stopband
This work presents a new miniaturized dual-band bandpass filter (BPF) featuring closely spaced passbands and wide stopband performance. The filter is designed on a slots-loaded substrate integrated waveguide (SIW) cavity fed by microstrip line. By introducing a longitudinal rectangular slot at the c...
