Design Of Compact Lowpass Filter with Wide Stopband using I-Shape

This paperpresents a compact micro strip stepped-impedance low pass filter with ultra-wide stop band byusing I-shape. Ground plane is etched with I shape. In this case, an wide stop band is achieved using Defectedusing I-shape. Ground plane is etched with I shape. In this case, an wide stop band is achieved using Defectedusing I-shape.
