Abstract
A filter comprising a linear array of a plurality of TL-inspired T-networks connected in series by capacitors, each TL-inspired T-network typically comprising a pair of conventional transmission lines connected in series with a circuit comprising pair of inductors and a single capacitor, the conventional transmission lines associated with each TL-inspired T-network being optionally combinable together or with conventional transmission lines in neighboring TL-inspired T-networks, wherein the circuit comprising a pair of inductors and a single capacitor is an artificial transmission line providing target characteristic impedance, which is same as that of the conventional transmission lines, and phase delay.
