## Abstract A compact nonresonating, dualβband bandstop filter is proposed. By connecting two transmission lines with proper characteristic impedances and phase delay (one is 90Β° and the other one is 450Β° in electrical length at center frequency), a dual stopband with two transmission zeros at each
