Wearable Panda-Shaped Textile Antenna with Annular Ring-Defected Ground Structure for Wireless Body Area Networks

Abstract

This research presents a compact panda-shaped wearable antenna with a defected ground structure (DGS). It is fabricated using a flexible material to work at 2.4-GHz industrial scientific medical (ISM) band, confirming the wireless body area network (WBAN) application requirements. The annular ring DGS and circular and elliptical slots in the patch aid in achieving the operating frequency. Good impedance bandwidth is maintained during on-body and bending analysis. Furthermore, this antenna exhibits a peak gain of 7.3 dB and a minimum specific absorption rate (SAR) of 0.0233 W/kg for 1 g tissue and 1.02 W/kg for 10 g tissue. The investigation shows that an antenna with good robustness, compact, high flexibility, and very low SAR makes it a strong candidate for WBAN applications.

Design and Analysis of a Low-profile Tapered Slot UWB Vivaldi Antenna for Breast Cancer Diagnosis

“…For breast cancer detection, Artificial Intelligence (AI) assisted algorithms can be utilized to identify the malignant tumor [23]. For on-body wearable applications, the antenna can utilize wearable substrate materials [24,25] and/or copper coated conductive fabric as a patch [26]. Further, analyzing the effects of bending makes it suitable for conformal applications [27].…”
