Fractal Multi Input Multi Output Antenna for WLAN Applications

A novel scheme of microstrip-fed fractal Multi Input Multi Output (MIMO) antenna with fractal patches for WLAN, systems is studied and presented. The operating frequency of the presented MIMO is from 4.1 GHz to 6 GHz, which covers 5.5 GHz band. The simulated and measured results of the proposed MIMO illustrate that the frequency range is set to 4.1GHz up to 6 GHz for impedance bandwidths. The presented MIMO has size of 15×30mm2. Different geometry and configurations of proposed MIMO array for multiple applications are studied. It illustrates that the attributes of small size, efficient radiation characteristic and less mutual coupling for MIMO application are promising.
