Performance Analysis of Novel Wearable Textile Antenna Design for Medical and Wireless Applications

The rectangular Horn–shaped wearable microstrip patch antenna is designed to resonate in the ISM (Industrial, Scientific, and Medical) band and other commercial wireless applications.The proposed multiband antenna is a wearable textile antenna with jeans material used as a substrate having relative permittivity, εr of 1.6. The physical dimensions of the antenna is 50 × 80 × 0.56 mm3. To generate the desired antenna to be applicable in ISM band, the slots are etched in the form of horn in the patch and the slotted ground plane is incorporated. The antenna provides percentage bandwidth of 44.3% at 2.4 GHz and 18.35% at 4.6 GHz.The antenna gain values are 4.74 dB and 3.71 dB at 2.45 GHz and 5 GHz frequencies respectively and VSWR is 1.21 at 2.45 GHz. The proposed wearable textile antenna is experimentally validated to be applicable for ISM band (2.4–2.484 GHz), WiFi (2.45 GHz), WiMax (3.3–3.9 GHz) and C-band (6.57–6.8 GHz) applications.
