This paper presents the design and analysis of a multiple-input-multiple-output (MIMO) textile antenna for wireless body area network (WBAN) applications. The MIMO antenna is comprised of four identical modified rhombus-shaped monopole antenna elements backed with a frequency selective surface (FSS) to improve gain and to reduce specific absorption rate (SAR). The antenna has an impedance bandwidth (S11 ≤ -10 dB) of 8.8 GHz (2.8-11.6 GHz) and isolation of >19 dB between the resonating elements. In order to assess the MIMO antenna's flexibility, the bending analysis is performed for various bending radii. The obtained diversity metrics are: Envelope correlation coefficient (ECC) < 0.5 dB, diversity gain (DG) < 10 dB, channel capacity loss (CCL) < 0.4 bits/s/Hz, and total active reflection coefficient (TARC) < -10 dB. The antenna's performance with and without FSS is evaluated for SAR investigation. The SAR values are reduced from 6.99 Watt/Kg to 0.0273 Watt/Kg with the aid of FSS. A peak gain of 8.08 dBi and maximum efficiency of 96 % are obtained with the FSS. The designed antenna is suitable for smart textile applications due to its low SAR, high gain, and wider impedance bandwidth.

A radio‐frequency identification antenna with a quasi‐endfire radiation beam and a vertical polarisation is presented. A size‐reduced magnetic dipole is used as the radiation source whose radiating waves are restricted by a dual‐layer metasurface to propagate along the horizontal direction and result in an endfire pattern. Two vertical metal plates are placed at both ends to induce magnetic currents to realise the vertical polarisation. Based on the near‐field power analysis, the proposed metasurface‐covered endfire antenna, which is conformal to fit compactly into a drawer with little influence on the storage space, can be used for smart home and smart library systems, such as intelligent storage and reading.
