摘要: In modern microwave design sector, Electromagnetic Band Gap (EBG) structures which is a unique innovation by virtue of their high potency and low complexity in designing with integrated circuits. This article examines the relationship between operating performance different substrates Tschebycheff polynomial distribution. A number methods, method moments (MOM) for numerical analysis distribution traditional circular pattern on ground plane are used. like manner, parametric comparison has been demonstrated view selectivity, 20-dB insertion loss bandwidth (20-dB IL BW) 10-dB return (10-dB RL BW). The consequence that is, two FR4 RT/Duroid 5870 prevail good matching upto 70 dB, negligible ripple less than 0.7 dB passband wider, deeper stopband 6–7.5 GHz. Improving compactness circuit efficiency, this complication solved
