Design of Polarized 2 × 2 MIMO Antenna Using Partially Stepped Ground

A 2 × 2 dual-band MIMO antenna is proposed for present wireless applications using partially stepped ground and polarization diversity techniques. The proposed design combines the horizontally and vertically polarized radiating elements. Using partially stepped ground (PSG) and orthogonally placed antenna elements, the effect of mutual coupling between radiators is reduced. The substrate of size 60 × 60 mm2 is mandatory to design the whole configuration. The resonated frequency bands extend from 3.39 to 7.91 GHz and 9.88 to 15 GHz with SWR < 2. The proposed 2 × 2 antenna has adjacent and diagonal ports with isolation 67.62 dB and gain up to 3.52 dB for operating frequencies 5.3 and 11.8 GHz. An envelope correlation coefficient \(\le 0.01\) has been achieved in the proposed antenna band.
