- Abstract
Flexible RF electronics and antennas made from textiles are regarded as a technology that accelerates the widespread popularity of modern wearable communication devices and components. This work presents a flexible and compact 4 x 1 rectangular microstrip patch array antenna for radio frequency (RF) energy harvesting applications. It operates at 5 GHz and has a high gain. The proposed antenna incorporates the inset feed technique to improve impedance matching and employs a conductive fabric (E-textile) as a conductor, along with textile as a substrate. The feeding and radiating structures are designed by using stick E shield conductive textiles that possess a conductivity of 5 x 105 S/m and are 0.085 mm thick. This design relies entirely on textile materials to ensure the user's comfort, ease of production, and cost-effectiveness. The Ansys HFSS simulator, which employs the finite element method, was utilized to optimize the antenna design. Subsequently, the suggested configuration was verified using the CST MWS simulator, which utilizes the finite integration method. The study aimed to achieve high gain and robust performance from the designed antenna. The simulation results demonstrate excellent performance within the operating band, with an impedance bandwidth of 6.78% and a high gain of 14.54 dBi at 5 GHz, making it well-suited for radiofrequency (RF) energy harvesting and wearable device applications.
