Planar Bandpass Filter Design Using Transversal Filtering
A new microwave single-passband planar filter using transversal filtering is presented.The proposed filter consists of transversal filtering sections.Three identical transversal sections are cascaded between the 50Ω input and output terminations and two addition stubs are implemented at the input and output transmission line.These stubs vividly reduce the insertion losses.The center frequency of the proposed bandpass filter is 2.6GHz.It is prototyped on FR4 substrate with dielectric constant 4.05,loss tangent 0.014 and thickness 1600 1m.The overall dimensional size is 72mm by 46 mm.Best measured matching return loss S11 is observed at 2.6 GHz with a value less than-15 dB.The passband insertion loss S21 is approximately -2.5dB.Attenuation for the lower stopband and upper stopband is greater than 40dB respectively.Both simulation and measurement results are presented and discussed.
