“…Smart textiles are designed to fit the body shape and ensure comfort for on-body usage [8,9]. Wearable textile antennas are considered for Wireless Body Area Network (WBAN), Wireless Local Area Network (WLAN), and mid-band 5G applications, where data transmission at high data rates is provided [10,12]. Technical problems such as antenna bandwidth, small size, and light weight have to be encountered for wearable antenna designs for 5G applications [13].…”

In this work, a novel all-textile washable metasurface antenna is designed for WBAN/WLAN and mid-band 5G applications. Metasurface antenna is obtained by implanting SRR (Split Ring Resonator) metamaterials that show left-hand characteristics to the patch plane. The metamaterial arrays consisting of 4 × 1 and 4 × 2 SRRs are placed to lateral sides of a circular patch. The performance of the antenna is verified by a full-wave electromagnetic analysis tool. The results show that metamaterial arrays significantly increase gain and efficiency values of the circular patch antenna. Metasurface antenna consisting of 4 × 2 array of metamaterials increases the efficiency from 74% to 94.5% and the antenna gain from 6.81 dBi to 9.43 dBi. Performance of the antenna is observed on conformal surfaces, as well. An analysis is carried out to calculate the peak specific absorption rate on an arm phantom. Patterns of vertically bended antenna in Ø =0 • and 90 • planes and low SAR values up to 30 dBm input power proved suitability of the metasurface antennas for on-body applications. The antennas are fabricated by using standard textile manufacturing techniques. It was confirmed by the measurement results that the metasurface formed by the linear SRR arrays increases the antenna gain. With its low cost, fabrication with standard off-the-shelf parts, high gain, and efficiency features, the proposed antenna can be used in wireless body area networks and 5G applications.

In this paper, a low-cost compact monopole UWB antenna with variable band notch characteristics is presented. The antenna is complemented on FR4 substrate with the whole size of . And the proposed antenna consists of a radiating patch with two symmetric semiellipse parasitic patches. A U-shaped slot is added to achieve a desired band notch frequency. It is excited by a 50 microstrip-line feed. A partial trapezoid ground plane with two symmetric L-shaped slots and two parasitic patches both can help to obtain higher frequency bandwidth more than 139% (2.8 GHz~15.6 GHz). The substrate with two circular holes can slightly improve the lower frequency characteristic. The simulation of the proposed antenna is achieved by CST Microwave Studio Software.
