摘要: Abstract A novel compact dual-band bandpass filter (BPF) based on short stub-loaded stepped impedance resonator (SSL-SIR) and a pair of tri-section (T-SIR) is presented. The BPF can be divided into two sub filters. upper creates the first passband centered at 2.4 GHz, lower generates second 3.5 GHz. passbands controlled separately have almost no mutual influence between each other. structure miniaturized wide stopband performance also achieved by introducing SIR. simulated measured results are both presented show good agreement.
