Design and analysis of I-shaped MIMO antenna for wireless applications

In this paper I-shaped MIMO antenna is designed in Ansoft HFSSv13 and fabricated. Now a day´s an array of antenna plays a wide role since it is very much useful to reduce the interference when the multipath propagation signal exists. In practical it can be helpful to our hand-held device called mobile phones since there is a need of array of antenna in base stations. The proposed antenna is designed over an operating frequency range of 2.57 GHz using the substrate material as FR-4 which has the dielectric constant of 4.4. This new shape of antenna has the swastika shaped slot between the patches which improves the efficiency and helps to reduce the prioritized parameter of mimo antenna which is nothing but the mutual coupling. This antenna can be applicable to the wireless communication areas such as Wi-Fi and WiMAX. The parameters such as return loss, VSWR, mutual coupling, directivity and gain has been simulated and analyzed. The mutual coupling has been achieved of about -30.5673 dB.
