“…It compares the performance of the investigated CP MIMO antenna to the previously published antenna design with AMC. It concludes that the proposed antenna has a smaller size compared with the designs reported in [4][5][6][7] and [12][13][14]. The presented antenna offers higher isolation S21 and FBR than the reported designs in [11][12][13].…”

“…Recently, several techniques for implementing the electromagnetic band gap (EBG) structures or artificial magnetic conductor (AMC) planes have been proposed to enhance the performance of wearable antennas. The AMC plane is used to eliminate the detuning effects, to increase the antenna gain and, meanwhile, reduce the back-lobe radiation as reported in [4,5,6,7]. Wearable textile antennas with different AMC backing structures have been reported in [4,5,6,7].…”

A compact high-isolation diversity and circular polarized (CP) multiple-input multiple-output (MIMO) fabric antenna for 2.4 GHz ISM band applications is presented. A metamaterial (MTM)-inspired radiating element is used for the miniaturization of the presented fabric antenna. The proposed antenna is fabricated on a denim substrate and has a dimension of 58 mm x 23 mm x 1.6 mm. The circular polarization is achieved by trimming the two diagonal corners of the radiating elements. A defected ground structure (DGS) comprising two U-slots is placed underneath each radiator to increase the bandwidth of the presented antenna. The isolation characteristics between the two antenna elements are increased by 20 dB by cutting a slit in a ground plane. The proposed CP-MIMO antenna incorporates an artificial magnetic conductor (AMC) layer to limit backward radiation towards the human body and hence enhances the gain. This antenna has been created on a denim substrate with permittivity εr =1.6 and 1.6 mm thickness. The proposed antenna offers a fractional bandwidth of 6.6 % (2.38-2.54 GHz), and an impedance bandwidth about 160 MHz. The antenna has a peak gain of 2.5 dBi without AMC and 4.5 dBi with AMC. To validate the simulation results, a prototype for the proposed antenna has been fabricated and experimentally characterized. Due to its small size, low specific absorption rate (SAR), ease of integration, and robustness, this antenna is a good option for wireless body area network (WBAN) applications.
