摘要: In this letter, a novel transmission line configuration has been proposed to design sharp-rejection, bandstop filter (BSF) with wide rejection bandwidth. The bandwidth and the level of are controlled by characteristic impedances lines. Design equations obtained using lossless model. verified in microstrip fabricating prototype BSF -20 dB fractional 100% at stopband center frequency f0 = 1.5 GHz. structure is simple easy fabricate.
