Abstract
A reconfigurable bandstop filter consisting of a parallel coupled line and two varactor diodes is reported. The stopband of the filter can be tuned from 0.47 to 1.67 GHz by varying the capacitance of the varactor diodes. Although still present, the first harmonic is significantly attenuated.
