hi adl_48:
can you obtain good input impedance at multiband? and how good the bandwidth is at each band?
in the paper "A Modified Contour Integral Analysis for Sierpinski Fractal Carpet Antennas With and Without Electromagnetic Band Gap Ground Plane" by Ban-Leong Ooi, the autor used the side-fed and he got the good input impedance,but he didn't introduce how to chose the width of the feed microstrip line, i just want to simulate the model he provided, but i can't obtain the same results.
would you please to upload your simulation model here,this problem has bothered me for a long time?
