Creation of a soft circular patch antenna for bio-medical applications for 5G at frequency 2.45 GHz

In the medical field, efforts are currently focused on the development of devices implanted in the human body, to build a high-performance infrastructure and a working tool adapted to patients' needs. One such implanted device is the pacemaker, which is playing an increasingly important role in today's medicine. Moreover, in the general context of medical activities, we speak of telemedicine. This involves the transmission of medical information (images, reports, recordings) via antennae implanted or fixed on the human body, to obtain a remote diagnosis, specialist advice, constant patient monitoring, and a therapeutic decision. This paper presents a study and design of a circular flexible patch antenna with half-circle-shaped gaps on its sides and a slot on the opposite part of its feed; it is implemented on a bio-sourced type substrate intended for industrial, scientific, and medical applications. In addition, it is fed by microstrip technology, which features notches for impedance matching. In addition, this antenna offers improved performance compared with the literature.
