Article Preview

In this paper,a novel two-port bandstop filter based on coaxial cavity is proposed,which is different to the conventional bandstop filters based on microstrip or stripline.The design and simulated results show that the novel bandstop filter has a good performance,which are stopband rejection less than -80dB from 1920MHz to 1980MHz, return loss less than -20dB and insert loss more than -2 dB in two widebands from 1700MHz to 1910MHz and 1990MHz to 2200MHz,respectively. Moreover,the measured results have good agreement with simulated results.
