This paper presents a novel design of a flexible and wearable E-shaped, multiband dipole antenna. The antenna has a low profile and is printed on a common 2 mm thick denim fabric ( ε r = 1.7 ). By installing a passively coupled rectangular patch with L-shaped cuts, the lower frequency band is supported and the bandwidth at higher frequencies is also enhanced. The antenna’s performance was observed under different deformations in free space as well as when it was placed on different parts of the human body. No significant changes in the characteristics of the frequency bands of interest were observed for the flexible antenna compared with the initial nondeformable antenna. Simulations for 10 g average specific absorption rate (SAR) at different input powers up to 250 mW were carried out considering that the antenna adheres well to the human body and there is no spacing or shielding. The obtained results show that the amount of energy absorbed by the body tissue increases by increasing the incident power.

“…5 For the design of wearable antennas utilizing textile substrates, low dielectric constant is selected to the reduce surface losses and provide wider impedance bandwidth. 6,7 During the design paradigm of wearable antennas, various substrate and conductive material are chosen on the basis of implementation and requirements. The antennas designed on hard rigid substrates are not suitable for wearable applications [8][9][10][11][12][13] as they do not provide flexibility of usage to the user.…”

This communication presents a multiband on-body conformal and wearable antenna for Wireless Body Area Network (WBAN) applications. The suggested wearable CPW-fed slot dipole antenna is incorporated with inductively coupled meander shape, T and O shaped resonators that lead to provide multiband operation. The resonant frequency is controlled by a definite resonant path, which leads to high degree of freedom in design paradigm. The proposed wearable antenna covers the 2.4 GHz/5.2 GHz/5.8 GHz WLAN, 3.5 GHz WiMAX, and 4.4 GHz C-bands and has an overall dimension of 60 × 40 × 0.254 mm 3. The SAR analysis has also been presented for the antenna at several resonant frequencies which are well under the normal SAR criteria of 1.6 W/kg that suggests that the model performs satisfactorily for wearable applications. To characterize the performance of the antenna, the specimen of the antenna is rigorously tested in terms of antenna gain, S-parameters and flexibility under different bending configurations for radii values ranging from 90 to 30 mm. The reflection coefficient of the suggested antenna is also evaluated and the outcomes are compared under distinct on-body circumstances. Measured and simulated results of S11, radiation pattern and gain are in good agreement.

“…The square slot CPW fed antenna is used for ultra-wideband application which is resonating at the frequency range of 3.2 GHz to 16.3 GHz & provides a bandwidth of 135 MHz used for wearable applications [1]. The fully textile-integrated microstrip-fed slot antenna is designed with a directivity of 4.9 dBi & S11 parameter -34 dB at 5.9 GHz frequency for dedicated short-range communications [2] [9]. This paper consists of single rectangular patch designed in the frequency range of 2.4GHz to 2.485 GHz which covers WiFi application.…”

Wireless body area networks have paying more attention in the recent decade. The microstrip textile antenna used for wireless applications (ISM Band) such as emergency rescue, health monitoring and medical care. In this paper, the square patch microstrip textile antenna is introduced which is mounted on the flexible jeans substrate. The physical size of the suggested/simulated textile antenna is 52.99 X 45.23 mm2 & the jean’s material is used as substrate with its relative permittivity of ɛr = 1.67. The proposed antenna is radiating at the center frequency of 2.45 GHz with a return loss of -15.76 dB & VSWR 1.389, the far field directivity of an antenna is 8.05 dBi at 2.45GHz. The designed antenna is wearable on the clothes because the use of textile material for antenna fabrication by keeping SAR at 1.6 W/Kg.
