摘要：
A modified lambda/4 stepped impedance resonator (SIR) is proposed, in which a shunt open stub is loaded between the low impedance line and high impedance line of a conventional lambda/4 SIR. Based on this modified lambda/4 SIR, a compact dual-band bandpass filter (BPF) with high selectivity is presented. Two transmission zeros (TZs) are generated near each passband for high selectivity. To demonstrate this method, a 2.4/5.2 GHz dual-band BPF for WLAN application has been designed, fabricated and measured. The measurement result shows four finite TZs in the stopband, located at 1.82, 3.14, 5.35, and 7.63GHz, respectively. The circuit only occupies 0.06 lambda gx0.09 lambda g.
