Planar Textile Antenna for Body Centric Wireless Communication System

Abstract

Abstract-One of the most important aspects for body centric communication is the development of the textile antenna for on-body communication. Antennas for on-body environment usually suffer performance degradation caused by the human body. Apart from that, textile antenna gets easily bent, flexed, wrinkled or wet. This paper presents an investigation on three different designs and types of planar antennas, which are single band textile dipole antenna, fractal Koch multiband dipole antenna and monopole ultra wide band antennas. The performance of the antennas has been evaluated in terms of bending, wetness condition and on-body simulation. The results show that the bending effect is not critical in free space for the planar antennas, but the performance is notably degraded under wet condition while the antenna reflection coefficient is shifted when placed on the human body.

“…Even if that were possible, there are all the practical and engineering reasons why a vertically coupled stack of LED/Solar cell stack makes sense, such as lowering cost, saving power, reducing electrodes, and reducing reflective glare that upset contrast in emissive displays. Such structures, known as photovoltaic organic lightemitting diodes, have already been documented in the literature [842,844] (see Figure 78), and are still considered to be in a relatively early development phase.…”

Truncated Patch Antenna on Jute Textile for Wireless Power Transmission at 2.45 GHz

“…The effect of the permittivity and tan δ values is shown by the given results. When permittivity increases, the patch surface is reduced as explained in equation (1), but the radiation efficiency Qr decreases. When the tan δ increases, the gain is reduced, and the bandwidth is enlarged.…”

“…In recent years, using textile as substrate has been used in many microwave applications [10]. In this study, the characteristics of jute are measured in the frequency band [1,5] GHz. This textile is interesting because it's made from natural fibers, so it's environmentally friendly.…”

“…Many of the applications work in the proximity of the human body to enhance the quality of life [1], [2]. In [3], the authors made a taxonomy of electronic applications on the human body: Body sensor network (BSN), body area network (BAN), wireless body area network (WBAN) [4].…”
