Fractal Antenna, Multiple-Input-Multiple-Output Antenna, Self-Similar Structure, Ultra-Wideband


This fractal geometry is designed by using iterated design function (IDF).The self-similarity dimension of proposed fractal geometry is 1.79, which is a fractional dimension. Self-similar fractal geometry is used there to achieve miniaturization and wide-band performance. A ground stub of T-shape with vertical slot enhances isolation and impedance band-width of proposed MIMO antenna. The antenna consists of 2 novel self-similar fractal monopole antenna elements and there metallic area is minimized by 29.68% at second iteration. This antenna has compact dimension of 24 x 32 mm2 and impedance band-width of 9.4GHz ranging from 3.1 to 12.5 GHz with isolation better than 16dB. There is a good agreement between measured and simulated results, which confirm that the proposed antenna is acceptable for UWB applications. The various diversity performance parameters are also determined. Thus a novel compact self-similar fractal ultra-wideband (UWB) multiple input multiple output (MIMO) antenna is presented.
