“…Moreover, the radiation efficiency and the gain of 79% and 3.5 dBi were obtained, respectively. In [ 277 ], a cuff-shaped button antenna was designed at the ISM and UNII bands, which was a circular patch with a diameter of 22.3 mm. The shape of a cuff button was conceived from a square-shaped polytetrafluoroethylene (PTFE) taconic ceramic material and its dielectric constant was considered 10.…”

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.

This communication presents a multiband on-body conformal and wearable antenna for Wireless Body Area Network (WBAN) applications. The suggested wearable CPW-fed slot dipole antenna is incorporated with inductively coupled meander shape, T and O shaped resonators that lead to provide multiband operation. The resonant frequency is controlled by a definite resonant path, which leads to high degree of freedom in design paradigm. The proposed wearable antenna covers the 2.4 GHz/5.2 GHz/5.8 GHz WLAN, 3.5 GHz WiMAX, and 4.4 GHz C-bands and has an overall dimension of 60 × 40 × 0.254 mm 3. The SAR analysis has also been presented for the antenna at several resonant frequencies which are well under the normal SAR criteria of 1.6 W/kg that suggests that the model performs satisfactorily for wearable applications. To characterize the performance of the antenna, the specimen of the antenna is rigorously tested in terms of antenna gain, S-parameters and flexibility under different bending configurations for radii values ranging from 90 to 30 mm. The reflection coefficient of the suggested antenna is also evaluated and the outcomes are compared under distinct on-body circumstances. Measured and simulated results of S11, radiation pattern and gain are in good agreement.

In this paper, a new design method is proposed for a planar and compact dual-band dipole antenna. The dipole antenna has arms as a hybrid CRLH (Composite right- and left-handed) transmission-line comprising distributed and lumped elements for the dual-band function. The two arms are fed by the outputs of a compact and printed CRLH dual-band balun which consists of a CRLH hybrid coupler and an additional CRLH phase-shifter. Its operational frequencies are 2.4 and 5.2 GHz as popular mobile applications. Verifying the method, the circuit approach, EM (Electromagnetics) simulation and measurement are conducted and their results turn out to agree well with each other. Additionally, the CRLH property is shown with the dispersion diagram and the effective size-reduction is mentioned.
