Telemedicine and implanted healthcare devices, such as pacemakers, rely on antennas to transmit medical data including images, reports, and recordings for remote diagnosis, monitoring, and treatment decisions. A circular flexible patch antenna has been designed for use in industrial, scientific, and medical applications. The design incorporates half-circle-shaped gaps along its sides and a slot positioned opposite its feed line. Built on a bio-sourced substrate, the antenna employs microstrip feed technology containing notches specifically for impedance matching. The resulting flexible device demonstrates improved operational performance when compared with existing alternatives documented in literature, supporting potential roles in wireless biomedical data transmission.
Flexible antennas on bio-sourced materials are central to the development of wearable and implanted medical devices. By enabling the wireless transmission of patient data, such as recordings and scans, these components facilitate continuous remote monitoring and telemedicine. This allows clinicians to deliver timely diagnoses and adjust patient care without requiring in-person hospital visits.
This antenna design could support commercial applications in telemedicine systems and body-worn or implantable healthcare devices like pacemakers. Medical device manufacturers and healthcare providers managing remote patient monitoring are the primary prospective users. Because the work is focused on the design and performance comparison of the antenna component, it currently sits at an early stage of laboratory research and development prior to real-world clinical validation.

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.
