Abstract

An antenna which is used for multipurpose like WiMAX, RADAR altimeter and X-band applications proposed. A tri-band multiple-input–multiple-output antenna resonates at 2.9 GHz, 4.3 GHz and 7.7 GHz is proposed. The uniqueness of the antenna is mutual coupling, − 53.44 dB at 2.9 GHz, − 28 dB at 4.3 GHz and − 26.55 dB at 7.7 GHz. It is evaluated in terms of mutual coupling in two ways (1) DGS (2) DGS with Vias. It is observed that mutual coupling using DGS with Vias is reduced further by 12 dB. The ECC of antenna is less than 0.0001 The simulated and measured results are compared in terms of S-parameters, Co-pol, X-pol and ECC.
