Miniaturization of a conformal dual-band wearable textile monopole antenna for WBAN and WLAN applications

This work presents a miniaturized dual-band wearable textile microstrip antenna with conformal traits and robust performance covering 2.45- and 5.38-GHz wireless body area network (WBAN) and wireless local area network (WLAN) bands. The antenna size is 78% smaller than a conventional antenna. The proposed antenna design incorporates the logo of the Algerian Petroleum Corporation (Sonatrach). The antenna is designed on a low-cost and lightweight denim material as a dielectric material and provides −10-dB impedance bandwidth for dual bands from 2.37 to 2.51 GHz and from 4.99 to 5.72 GHz. The prototype is fabricated and validated through measurements. The measured results show good agreement with the simulation results. Additionally, the antenna performance near the human body is investigated, yielding satisfactory outcomes in both free space and proximity scenarios. The proposed antenna design is a low-cost solution for various wearable consumer electronics applications. This antenna presents itself as a potential solution for enhanced workforce management, secure access control, and identification.
