A Dual-Band Printed Slot Antenna for WiMAX and Metrological Wireless Applications
Main Article Content
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.
