Design of modified Sierpinski antenna for WLAN applications

The Sierpinski (SPK) geometry has a paramount application in multiband antennas. The multifrequency characteristics of the SPK are characterized by its scaling factor and successive iterations. To allocate more number of bands the geometry has to undergo more number of iterations which makes the antenna more complicated for fabrication. In this work we propose modifications to the SPK geometry with the ability of allocating two frequencies close to WLAN applications. The designed antenna preserved its multiple frequency characteristics and are verified with the radiation plots.
