Multiple input miniaturized fractal antenna for terrestrial services

A Minkowski fractal shape patch antenna covering terrestrial wireless services is presented for multiple-input-multiple-output implementation. The proposed structure is minimized up to two iteration operated at 10GHz. The end to end separation between the two antennas is 4.9mm The existence of surface waves is reduced using two inverted T and slot structure respectively, which is etched in between the two antennas at the ground plane. The designed two element antenna has a reduced mutual coupling of -37dB with perfect de-correlation at 10GHz operating frequency.
