Abstract

A novel coplanar waveguide Tri-band bandpass filter (BPF) based on impedance and admittance inverters is presented in this paper. Based on the impedance and admittance inverters analysis, the tri-band BPFs first three resonance frequencies can be conveniently controlled. Benefiting from this feature, the impedance and admittance inverters can be utilized to implement a tri-band BPF. To demonstrate the proposed concept, a tri-band BPF using an impedance and admittance inverters are implemented. The experimented results verify the theoretical predictions and simulations at 1.9GHz, 2.45GHz and 5.8GHz respectively.
