摘要：
This paper proposes a new dual-passband microstrip bandpass filter, which is composed of two asymmetric half-wavelength resonators and four shunt open stubs that provides four transmission zeros. Two short stubs are added to suppress the second harmonic. The relationship of the four transmission zeros and the dimensions of the filter are all provided. The dual-passband microstrip bandpass filter is fabricated with the first passband of 2.4 GHz corresponds to the bandwidth of 0.1 GHz and the second passband of 5.7 GHz corresponds to the bandwidth of 0.25 GHz. The insertion loss of the two passband is less than 1 dB and 3 dB, respectively and the return loss is more than 10 dB. The results of the measured and simulated data agree well.
