A modified sierpinski carpet antenna structure for multiband wireless applications

Multiband patch antenna has a very important part in the communication devices and systems. The benefits in designing and testing of Sierpinski carpet geometries for a low profile, cost effective multiband microstrip patch antenna for wireless standards is reviewed in this paper. The basic structure of the patch antenna is designed using the FR4 substrate with a thickness of 1.3 mm. The designed patch antenna structure is excited using the microstrip feed system. The Sierpinski carpet antenna structure is designed and simulated using High Frequency Structural Simulator (HFSS) software. The available Sierpinski carpet antenna structure in the literature is modified to make the preferred radiation patterns. The effects of the iterations of the modified Sierpinski carpet antenna structure over the generated return loss plots are discussed in this work. Based on the generated multiband behavior in the simulated results, the accomplishment of the designed antenna in the wireless domain was analyzed.
