“…Nevertheless, we shall separate the two types of temporal signal variation for both the antenna types and compare the statistics for the two cases. This has been done for the monopole antennas in [3]. The same procedure have been used in this paper, i.e.…”

Propagation between two antennas on a human body in millimeter-wave frequency band have been investigated empirically. Propagation characteristics of a number of on-body propagation channels were studied with two types of antennas: quarter-wavelength monopoles and rectangular horns, the first being representative of low-gain omnidirectional antennas and the latter being the high-gain directional antenna. The channel characteristics for the two types of the antennas were compared. The path gain of the links with the horn antennas was found to be higher the that for monopoles. However, the variability of the path gain was also much greater for some channels. The path gain variation with time was described by a two-scale statistical model in which short-term fading was found to follow approximately Cauchy-Lorentz probability distribution.

“…As one of the key components in the communication system, wearable antennas have received much attention in both academia and industry since their unconventional operating environment is in extremely close proximity to the human body [4]. In this case, the loading of lossy human tissue makes the design of a high radiation efficiency antenna challenging when it is also desirable for it to possess light-weight and low-profile characteristics [5,6]. Simultaneously, the impact of a wearable antenna on human tissue, characterized by the specific absorption rate (SAR), also needs to be minimized.…”

Abstract-This paper presents a compact, low-profile, wearable dual-band antenna operating in the Wireless WLAN band of 5.15 ∼ 5.25 GHz and 5.72 ∼ 5.83 GHz. The proposed antenna is composed of a planar monopole and underneath three by three array arrangement of Jerusalem Cross (JC) structure metasurface. The simulated results show that the integrated antenna express 4.09% and 4.14% impendence bandwidths, increased gain up to 7.9 dB and 8.2 dB, front to back (FB) ratio achieved to 20 dB and 18 dB at the two frequencies, respectively. The measured results agree well with simulations. In addition, the metasurface not only is equivalent to a ground plane for isolation, but also acts as the main radiator, which enables a great reduction in the specific absorption rate (SAR). Furthermore, because of a compact solution, the proposed integrated antenna can be a promising device for various wearable systems.

Abstract-Wireless body area networks have raised considerable attention within the wireless personal area community. To optimize the network architecture and the energy consumption of on-body equipments, a good knowledge and understanding of the radio link and the propagation channel are required. This work addresses the influence of medium presence on the reflection loss of horn and textile antennas. In particular, the path loss in free space and under skin-equivalent phantom of horn-to-horn and textile-to-textile communications is presented. The obtained results show that the path loss differs considerably in the analyzed situations; with horn-to-horn links showing a path loss exponent between 1.13 and 2.35, while it is reaching 4.7 for textile-totextile links. The obtained results provide additional input for the design of communications links in the context of future 5G and IoT eco-systems.
