“…The SAR values over the frequencies are very much within the FCC limits of 1.6 W/Kg value for a 1 g tissue model [17]. Further, if the proposed monopole antennas are to be placed in a near proximity to humans (without the usage of ground plane), then electronic band gap structures can be used for the SAR reduction as in [18]. The comparisons of the proposed antennas with existing antennas in terms of bandwidth, peak gain and size are shown in Table 3.…”

Abstract-Compact wideband flexible monopole antennas are designed and analyzed for its performance for Body Centric Wireless Communications (BCWC). Two antennas with identical radiators on different substrates are designed and fabricated on polyamide and teslin paper substrates, deploying a modified rectangle-shaped radiator. With the aid of modifications in the radiating plane and defecting the ground plane, the polyamide based antenna is designed to operate between 1.8 and 13.3 GHz, and teslin paper based antenna is designed to operate between 1.45 and 13.4 GHz to cover the wireless communication technology frequencies and ultra-wideband range for various wireless applications. The reflection coefficient characteristics of the fabricated antennas on free space and on various sites of the body are measured and match reasonably well with the simulated reflection coefficient characteristics. The specific absorption rate (SAR) analysis is also carried out by placing the antennas on tissue layered model.

“…As a result, one can say that the proposed antenna has lower 1 g average SAR value than the antennas in [5,6,8,9], and smaller dimensions than those in [5,6]. Moreover, the proposed antenna has a broader bandwidth than antennas in [5,6,9] and better radiation efficiency than [19] when it is mounted directly on a human tissue model as a wearable antenna for body-centric communications. Other advantages of the proposed antenna are the low cost and simple fabrication process.…”

“…Different design approaches have been proposed: (i) using metasurfaces [5], including electromagnetic band-gap structures [6], (ii) using artificial magnetic conducting surfaces [7], (iii) high impedance surfaces (HIS) [8] or (iv) antenna with full ground plane [9]. The presence of the metasurface or full ground plane improves antenna performance while decreasing backside radiation.…”

Abstract-This paper presents the design of a flexible antenna using planar dipole with a reflector to achieve optimal radiation efficiency and low specific absorption rate (SAR) when the antenna is placed directly over the skin of body model. The antenna is designed for the 2.45 GHz frequency band. The parametric analysis of the proposed antenna is carried out. The proposed antenna achieves stable onbody performance: |S 11 | varies from −16.05 dB (on skin) at 2.47 GHz resonant frequency to −16.40 dB (in free space) at 2.44 GHz resonant frequency. It was found that the maximum 1 g average SAR value is only 0.23 W/kg for an input power of 100 mW when the antenna is placed directly over the skin of a three-layer body model, and radiation efficiency is 20.5%. The measured results are presented to demonstrate the validity of the proposed antenna.

“…Table 2 gives the details of the curvilinear surfaces used for the measurement. There are works on analysis of performance of antennas on curvilinear surfaces [18][19][20][21][22][23][24]. Even though the reflection coefficient results are not reported in [18][19][20].…”

This study brings out the design, fabrication and performance evaluation of a compact, dual band antenna on paper substrate. The two bands of operations are 2.18 to 2.50 and 5.22 to 5.72 GHz. These bands are used by the wireless sensor networks (WSNs) and radio frequency identification systems (RFID). The antenna becomes useful for the WSN nodes and RFID systems at these frequencies. The overall size of the antenna is 40 mm × 20 mm × 0.6 mm, which makes it a compact one. Antenna was tested for the effect of bending by placing it over curvilinear surfaces. The bending was done in horizontal (X) and vertical (Y) axes. These examinations will help to understand the effect of wind loading and other packaging related bending on antenna performance. The main features of this antenna are stability in performance under bent conditions, simple configuration and low cost of fabrication. A thin polyethylene layer has been used to laminate the antenna for permanence. The effect of lamination has also been explained in the course of the study.
