Extended Composite Right/Left-Handed Transmission Line and Dual-Band Reactance Transformation

Figure 4

Simulated attenuation responses of the dual-band bandpass filters transformed from 1-dB Chebyshev low-pass filters for filter orders of 3, 4, and 5. (The response of the lower and upper pass bands in the upper subplot is amplified in the left and right bottom subplots, resp.)
