Abstract

One among the fast-growing trends in wireless standards is multiple-input-multiple-output (MIMO) antennas. It has attracted researchers all over the world to design electronic devices with prominent bandwidth. The proposed design consists of two rectangular patch shaped antenna arranged in a way to form multiple-input-multiple-output (MIMO) antenna which operates at two resonating frequencies such as 6.6 GHz and 12.77 GHz. We have implemented E-shaped and U-shaped slots in the radiating patch of the antenna. Parasitic structure has also been embedded on the backside of the substrate to improve isolation and it also consists of partial ground plane. The substrate is made of FR-4 material with a thickness of 1.6 mm, a length of 25 mm and a width of 36 mm. The bandwidth obtained is a dual-band of frequencies such as 5.22 to 8.94 GHz and 12.74 to 12.81 GHz. The return loss obtained at 6.6 GHz is -23.90 dB and at 12.77 GHz is -18.41 dB. The isolation achieved is -38.48 dB and -42.47 dB with also a peak gain of 5.00 dB.
