“…A dual-band and dual-sense wearable antenna was designed, which operates in GPS and WLAN band with linear and circular polarization, and the AMC plane provides a decrease of backward and improvement of gain and bandwidth. The unite cell and its reflection phase are shown in Figure 10 a,b, and the antenna prototype is shown in Figure 10 c [ 101 ]. Next, Yan et al proposed an efficiently radiating wearable antenna by replacing the normal metallic ground plane with an AMC plane, as shown in Figure 11 .…”

Wireless Body Area Network (WBAN) has attracted more and more attention in many sectors of society. As a critical component in these systems, wearable antennas suffer from several serious challenges, e.g., electromagnetic coupling between the human body and the antennas, different physical deformations, and widely varying operating environments, and thus, advanced design methods and techniques are urgently needed to alleviate these limitations. Recent developments have focused on the application of metamaterials in wearable antennas, which is a prospective area and has unique advantages. This article will review the key progress in metamaterial-based antennas for WBAN applications, including wearable antennas involved with composite right/left-handed transmission lines (CRLH TLs), wearable antennas based on metasurfaces, and reconfigurable wearable antennas based on tunable metamaterials. These structures have resulted in improved performance of wearable antennas with minimal effects on the human body, which consequently will result in more reliable wearable communication. In addition, various design methodologies of meta-wearable antennas are summarized, and the applications of wearable antennas by these methods are discussed.

“…Nowadays, the artificial magnetic conductor (AMC) is widely used in antenna designs. It can reduce the height of antenna by using the in‐phase reflection characteristics, and improve the impedance bandwidth (IBW) and radiation performance of the antenna by the surface wave propagation characteristics in References 9‐14. In Reference 9, various monopole antennas with different types of AMC reflectors were investigated, and the impedance matching of the antennas were significantly enhanced.…”

A low‐profile dual‐band circularly polarized (CP) antenna with wide beamwidth is proposed in this article. The proposed antenna is composed of three layers of spiral patches, an artificial magnetic conductor (AMC) reflector and a four‐feed network. The three‐layer spiral patches as a quadrifilar helix antenna are employed to achieve dual‐band CP radiation. Then, a metal ground is replaced by one square‐shaped AMC surface to improve the antenna performance. With these antenna structures, the antenna size is only 0.36λ0 × 0.36λ0 × 0.106λ0 at 1.268 GHz. The antenna exhibits the impedance bandwidth ranging from 1.17 to 1.39 GHz and 1.49 to 1.58 GHz (|S11| < −10 dB). Furthermore, the proposed antenna has excellent axial ratio beamwidths of 171° at 1.268 GHz and 201° at 1.561 GHz. With these excellent characteristics, the designed antenna can be well applied to global navigation satellite systems.

In this paper, a three-band wearable antenna with coplanar waveguide (CWP) feed based on an artificial magnetic conductor (AMC) is presented. The antenna consists of a monopole antenna with an array of 4×5 AMC cells, using polyimide as the substrate, with overall dimensions of 124 mm × 155 mm × 8.9 mm. Three open inverted triangles form an independent monopole antenna, with each open inverted triangle corresponding to one band. The AMC unit is composed of three regular octagons produces zero phase reflection at the center frequency of the corresponding three bands. The design operates at 1.8 GHz, 2.4 GHz, 3.5 GHz, can be used in all three LTE 1800/WLAN/WiMAX bands and be applied to widely integrated into a variety of wearable devices. The gain of the three frequency points increased by 10.1dB, 2.86 dB and 5.06 dB respectively. In this paper, the antenna has been simulated with different degrees of bending performance, as well as the analysis of the effect of human tissues on the performance of the antenna. The results show that the antenna has good bending characteristics.
