New microstrip antenna initiated from the portions of  1st order structures of Sierpinski square geometry is  modeled  in this paper as quasi-fractal device using an FR4 substrate of 4.4 dielectric constant, 1.6 mm thickness and 0.02 loss tangent. The intended microstrip antenna is designed for band frequencies  of 3.5 and 7.8 GHz for WiMAX and metrological satellite applications with a bandwidth of 0.66 and 0.78 GHz for each band respectively. The designed antenna has considerable compact size  that is smaller than many reported fractal and non-fractal antenna structures in the literature. Also, it has interesting return loss and radiation results that can be employed in diverse wireless devices. Measured input reflection coefficient, radiation patterns and gain results have been found in good agreement with those predicted by simulations.
