A compact, wideband, two‐element textile multiple‐input‐multiple‐output (MIMO) antenna is presented for industrial, scientific and medical (ISM)/wearable applications. The proposed structure is composed of the Felt material substrate, and the ground plane and radiating patch are formed using ShielditTM Super conductive material. The designed MIMO antenna offers a wide impedance matching bandwidth (S11 ≤ −10 dB) of 2.00−6.23 GHz, a very low mutual coupling of (S21,max) −29.26 dB, low envelope correlation coefficient <0.01, high diversity gain ∼9.95 dB, and realized gain of more than 2.88 dBi, over the entire band. The prototype of the proposed antenna geometry is fabricated, and it has a size of 76 × 37 mm2. The proposed antenna could be a good candidate for wearable electronic devices due to its compact size, all textile layers, easy integration, robustness, and reasonable on‐body performance.
