A Compact Multiband Gasket Enable Rectangular Fractal Antenna

The design of a new fractal multi band antenna, based on Sierpinski gasket enabled rectangular geometry is presented in this paper. Two iterations of the rectangular fractal multi band antenna, with CPW feeding in 2-10 GHz band are examined. There appeared 3 resonant frequencies at 2.46 GHz, 3.7 GHz and 5.5 GHz for 2nd iteration. From the return loss plot it is seen that antenna has achieved the IEEE Bluetooth/WLAN/ISM (2.4-2.484 GHz), WiMAX (3.4-3.69 GHz) & WIFI (5.1-5.825 GHz) frequency band with-10dB return loss. Also nearly omni-directional radiation pattern is observed. The peak realized antenna gain is around 4.5 dB in each distinct band.
