Design and Analysis of UWB MIMO Antenna for Smart Fabric Communications

This paper presents a flexible multiple-input, multiple-output (MIMO) antenna with ultrawideband (UWB) performance for smart clothing applications. The MIMO is comprised of four octagonal-shaped radiators several slots loaded into them, and it offers frequency range 2.9–12 GHz. unit cell has size 0.26λ0 × 0.164λ0 0.014λ0 the 0.48λ0 0.014λ0, where λ0 corresponds to lowest operating frequency. radiation diversity performances are evaluated, obtained metrics envelope correlation coefficient (ECC) <0.045, gain (DG) >9.9 dB, total active reflection (TARC) <−14 channel capacity loss (CCL) <0.13 bits/s/Hz. bending analysis performed. specific absorption rate (SAR) also investigated, values 0.229 W/Kg (4 GHz), 0.253 (7 0.463 (10 GHz).
