Design and development of printed Sierpinski Carpet, Sierpinski Gasket and Koch Snowflake fractal antennas for GSM and WLAN applications

摘要

In this paper, three configurations of printed fractal antennas, such as Sierpinski Carpet, Modified Sierpinski Gasket and Koch Snowflake are designed and developed for multiband operations for GSM 1800, WLAN 2400/5800 applications. The antenna performance is analyzed for their radiation characteristics. The simulation and experimental results depict 1:2 VSWR return loss around the desired frequencies. Also a modified design configuration of Sierpinski Gasket fractal antenna is proposed in this paper.
