Abstract

This work presents a single-layer wideband textile multiple-input–multiple-output (MIMO) antenna for wearable devices. The antenna design is made up of two rectangular-shaped monopole antennas that are mirror imaged and connected to achieve an equal voltage level in the ground surface. The antenna elements are excited by 50-Ω microstrip feed lines. By using a triangular stub decoupling element on the ground plane, greater than 22 dB of isolation is attained among antenna elements. The suggested two-element MIMO antenna has a bandwidth of 2.3–8.0 GHz and a dimension of 30 mm × 58 mm × 1 mm. In addition, four- and eight-element MIMO geometries have been designed and analyzed for massive MIMO applications. Also, an eight-element MIMO belt antenna for wearable straps is investigated. The effects of antenna bending on the human body are also investigated.
