## 5 Potentials of Textiles Technology in Wearable Antennas  
Textile technology is a well-established field where advanced techniques are employed to develop and manufacture various types of yarns and fabrics tailoring textile properties. Further, as has been outlined from the above analysis, the utilization of clothing components in wearable antenna technology has gained significant technological and scientific interest in the last years connecting the traditional sewing/embroidery industry with this futuristic e-textiles sector. The increasing demand for wireless functionalities within smart clothing could initiate new potentials of textile technology in the wearable antenna field. The potential could be general in terms of market and industry and specific regarding the clothing design and manufacturing procedure. The potentials can be listed as follows: (i) textile market expansion into electronics and antenna technology, (ii) manufacturing of clothing components to serve dual roles (clothes and antenna), (iii) low-profile and user-friendly antenna, and (iv) smart clothes for various applications taking into advantage (in terms of an antenna and electromagnetic performance) the existence of the mandatory clothing components. The following paragraphs expand each potential to offer a more crystal-clear view.  
The textile market has been a great economical sector for decades as clothes are an indispensable daily industrial product. Still, clothes can be altered into novel high-tech products via the combination of wearable electronics and antenna devices. Wearable technology is among the advancing parts of entertainment, health, and safety. This combination will give a great boost to wearable technology and could enable chances for the mass production of smart clothes for various applications.  
Presuming that a smart cloth is designed for a specific application (e.g., WLAN) by employing a clothing component as described in Section 2, then this component should be designed for a dual role: to be part of the cloth and part of the antenna, as well. Under these conditions, textile technology should upgrade the characteristics of the clothing components to allow for a more efficient exploitation of wearable antenna design. For instance, new buttons with satisfactory electrical conductivity could be developed, or zips in a closed state could create a more solid structure without gaps. Additionally, this (and in combination with the previous potential) will dramatically improve the specification of products in both technological sectors (textile and wearables).  
As can be easily distinguished from Section 2, the wearable antennas when using the clothing components should be low-profile, user-friendly, somehow \"hidden\" in garments, and made from textile materials, which in contrast with rigid materials are appropriate and aesthetically acceptable by users.  
Finally, all the above could enable from scratch design and production of smart clothes for various applications and communication systems (ISM, Bluetooth, WLAN, UWB, 5G, and IoT) which will efficiently exploit clothing components appropriate both for garment and wearable electronics functionalities.
