A Novel Wearable Circular Polarized Antenna Design for Wireless Power Transfer Systems in E-Health Applications

In this article, a new design based on a circular polarized antenna array 2X2 for use in wearable devices is presented. The objective of this work is to implement an efficient wireless power transfer (WPT). Our approach consist to address remote medical sensors using the 5.8 GHz ISM frequency band. We have carried out a detailed simulation of a rectenna system (a combination of antenna and rectifier circuit) for wireless energy transfer. The simulation model was developed to evaluate the system’s performance in terms of transmitted power and energy efficiency. The proposed receiver antenna not only exhibits excellent performance but also achieves an impressive gain of 9.47dB. The results obtained demonstrated the feasibility of remote wireless energy transfer in the medical field, using the 5.8 GHz ISM frequency band. The results of this research contribute to the development of more advanced and autonomous wireless medical monitoring systems, enabling better quality of care and greater flexibility in medical applications.
