Design of Tapped-line Bandpass Filter for Harmonic Rejection with Meander Spurline

In this paper, a harmonic rejection bandpass filter (BPF) is presented using the tapped-line geometry and the meander spurline to reject harmonics. The tapped-line structure suggested in this paper is simple and accurate. As the inverter is realized by meander spurline, the parasitic mode has been suppressed and the size of the filter is reduced about 20% at the same time. To validate the design, a prototype of λ/4 short stub BPF is fabricated and characterized. The BPF is fabricated on the substrate with dielectric constant of 2.54 and thickness of 0.54 mm. The measurement results show that the insertion loss and return loss are -1.3 dB and -11.3 dB at the center frequency of 2.45GHz and bandwidth of 12.2%, respectively.
