Abstract
This article presents a single-element,flower-shaped two and four-element MIMO(Multiple Input Multiple Output)antenna with enhanced bandwidth and gain. The array consists of identical elements on three commonly used textile substrates- cotton, jeans, and felt material. For each of the three substrates, the impedance bandwidth, reflection coefficient, and gain are used to assess the effectiveness of the recommended antenna.For the felt-based four-element MIMO antenna the outcomes of measurement and modelling are confirmed. Results reveal that the prototype provides a fractional bandwidth of 133.2%, spans the UWB range (3.1 to 10.6 GHz) and X-band (8 GHz to 12.23 GHz), and has a maximum gain of 16.96 dB.To investigate the MIMO performance, MIMO metrics were computed which include Envelope Correlation Coefficient (ECC), Diversity Gain (DG), Mean Effective Gain (MEG), Channel Capacity Loss (CCL), and Total Active Reflection Coefficient (TARC).
