“…Currently, various studies have been conducted to design various types of wearable antennas. Examples of antennas include the monopole planar antenna [ 261 ], planar inverted-F antenna (PIFA) [ 262 , 263 ], microstrip patch antenna [ 264 ], magneto dipole antenna [ 265 ], substrate-integrated waveguide antenna (SIW) [ 266 ], electromagnetic bandgap (EBG)-type antenna [ 267 ], dipole antenna [ 268 ], fractal patch antenna [ 269 ], and cavity slot monopole antenna [ 270 ]. Similarly, a Yagi-Uda antenna was also used for WBAN in the millimeter-wave (mm-wave) band [ 226 ].…”

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.

In this paper, we propose a metamaterial (MTM) structure with a reconfigurable property designed to operate at the millimetre-wave (mm-wave) spectrum. Four switches are used to achieve the reconfigurable property of the MTM with two configurations. These two configurations exhibit different refractive indices, which used to guide the radiation beam of the antenna to the desired direction. The proposed planar dipole antenna operates at the 5th generation (5G) band of 28 GHz. The electromagnetic (EM) rays of the proposed antenna pass through different MTM configurations with different phases, subsequently results in the tilting of the radiation beam toward MTM configuration of high refractive index. Simulated and measured results of the proposed antenna loaded by MTM demonstrate that the radiation beam is tilted by angles of +34º and-31º in the E-plane depending on the arrangement of two MTM configurations onto the antenna substrate. Furthermore, the gain is improved by 1.7 dB and 1.5 dB for positive and negative tilting angles, respectively. The reflection coefficients of the antenna with MTM are kept below-10 dB at 28 GHz.

“…However, the dielectric loss of the substrate should be obtained first. Transmission line method is feasible for the same purpose [29]. By measuring S21 with different transmission line lengths, the conductive loss can be extracted.…”

When compared with other antenna types, flexible and wearable antennas are generally characterized by compactness, reconfigurability, flexibility, and durability. Therefore, the fabrication processes and materials used in flexible and wearable antennas are quite unconventional and need to be addressed and evaluated. Moreover, additional measurement setups and tuning methods are often required in wearable and flexible applications to reflect a realistic setup and to yield a practical design and optimal performance. In this chapter, the fabrication and measurement techniques and related issues of flexible and wearable antennas are introduced and discussed in detail.
