In present work, a microstrip Sierpinski modified and fractalized antenna using multilayer structure to achieve dual band behavior for WLAN applications has been proposed. Due to the space-filling properties of fractal geometry, the proposed antenna is smaller in size than the conventional Euclidean-type. An equilateral triangular patch antenna with Sierpinski Gasket fractal shape has been designed and studied. An electromagnetic coupled stacked structure of two different patches operating at two frequencies (2.4 GHz Bluetooth and 5.8 GHz Wireless LAN) has been designed for dual band WLAN applications.
