Present article provides the design of an in-line parallel-coupled Chebyshev bandpass filter centered at 5.25GHz with a fractional bandwidth of 20% for WLAN applications. The coupled-lines are modified by asymmetric rectangular perturbations subject to strong and weak coupling. The proposed filter s...
