摘要：In this paper, a planar Electromagnetic Bandgap (EBG ) microstrip filter is formed by etching circles in the ground plane and using a modulated microstr ip line. These planar EBG structure configurations provide wide stopband with high attenuation but with ripples in the passband. To eliminate the ripples caused by the periodicity of EBG structure a variable Poisson distribution is used to taper components of the p roposed structure . A comparison of EBG structure with var iable α = 2, 3 and 4 of Poisson distribution is done. It is found that t he structure with α = 2 provides the largest bandwidth of 6.2 GHz and stopband attenuation of 29.27 dB with reduced ripples in the lower and upper passband
