“…The circular shape was used for the ISM band, whereas the truncated patch was used for the GPS band. In [ 297 ], the authors proposed an AMC based coplanar waveguide antenna for the ISM bands, as illustrated in Figure 11 b. The AMC structure improved the performance and provided the isolation between the antenna and the human body.…”

The demand for wearable technologies has grown tremendously in recent years. Wearable antennas are used for various applications, in many cases within the context of wireless body area networks (WBAN). In WBAN, the presence of the human body poses a significant challenge to the wearable antennas. Specifically, such requirements are required to be considered on a priority basis in the wearable antennas, such as structural deformation, precision, and accuracy in fabrication methods and their size. Various researchers are active in this field and, accordingly, some significant progress has been achieved recently. This article attempts to critically review the wearable antennas especially in light of new materials and fabrication methods, and novel designs, such as miniaturized button antennas and miniaturized single and multi-band antennas, and their unique smart applications in WBAN. Finally, the conclusion has been drawn with respect to some future directions.

“…Also, the effects due to electromagnetic intercoupling between the wearable MIMO antenna and the human tissue should be taken into account and the potential effects due to long term use must be noted 5 . Hence special precautions need to be addressed during wearable textile antenna design 6‐9 . Different real‐life circumstances are likely possible for the wearable antenna systems such as folding, bending, twisting washing, etc, which may degrade the antenna performance 10 …”

A lightweight multi‐input multi‐output (MIMO) two‐element wearable ultra‐wideband (UWB) antenna having a port isolation of greater than 21 dB is introduced in this communication. The proposed structure includes wearable jeans cloth as a substrate, wherein two inverted u‐formed stubs are mounted in the middle position located on the backside of antenna and attached to the partially etched ground for enhancing the characteristics of port isolation. The developed UWB MIMO antenna has a size of 50 x 35 mm2 and covers the frequency range operating from 1.83 to 13.82 GHz (~153.2%). The suggested MIMO antenna is inexpensive and functions across a broad frequency range of applications including WLAN (2.4‐2.484 GHz/5.15‐5.35 GHz/5.72‐5.825 GHz), Downlink‐uplink WiMAX (3.2‐3.85 GHz), and C‐band (3.7‐4.2 GHz/5.925‐6.425 GHz). The diversity gain (DG) is found to be greater than 9.9 along with envelope correlation coefficient (ECC) to be less than 0.059 across the entire operating bandwidth. The proposed MIMO antenna's channel power loss is bestowed to be less than 0.35 bit/s/Hz. The SAR results of the proposed UWB MIMO design admits that the antenna performs satisfactorily and is suitable for wearable applications. Simulation and testing fairly proved the output of the proposed antenna as a righteous candidate applicable for UWB MIMO applications.

“…To insulate the antenna from human tissue, a multiband AMC surface is incorporated on the opposite side of the radiator and presented in Reference 7. A coplanar waveguide AMC antenna operating at 2.45/5.8 GHz with reduced SAR is reported in Reference 8. In Reference 9, they have described a compact, flexible, slotted Jerusalem Cross AMC antenna operating at 2.45 GHz for telemedicine applications.…”

In this article, two miniaturized, dual-band, enhanced gain, flexible, low specific absorption rate (SAR) artificial magnetic conductor (AMC) integrated antennas operating at 2.4 GHz ISM and 3.9 GHz WiMAX bands have been proposed. Two compact monopoles with defected stepped ground structures have been used to improve the radiation characteristics while integrated with a common AMC surface. Defected dumbbell shaped unit-cell has been designed to obtain zero reflection phase and modify the material features. The capacitive effect of the AMC along with the defected stepped ground structures of the monopoles have excited two resonating bands and miniaturized the antennas. Proposed AMC has compensated the out-of-phase radiation toward main beam direction to increase the gain up to 8.6 dB, which is 85% more than that of the only monopole. The AMC has enhanced the reflectance exploiting the double-negative property and made the emitted radiation more directives. The integrated antennas have bestowed robust impedance matching in various bent condition by virtue of in phase reflection property. SAR values have been suppressed significantly up to 0.021 W/kg at a distance 5 mm from the human body, which is 99.5% better than that of the monopole alone
