Abstract

Telemedicine technology is one of the key achievements of recent years. This technology is based on biomedical devices that contain essential components, in-cluding antennas. Biomedical antennas ensure the exchange of data between de-vices installed on the human body and the external environment. This paper pre-sents the study and design of a flexible circular patch antenna implanted on a bio-sourced substrate for industrial, scientific, and medical applications. The frequen-cy chosen for the study is 2,45GHz. Return loss and radiation pattern measure-ments. An improvement in the gain of this antenna is also investigated in this study. This antenna offers adequate performance to meet the needs of 5G users. This antenna is printed on a polyester substrate with a thickness of h=2,85cm, a relative permittivity εr=3,2, a loss tangent equal to 0,003, and a patch radius equal to 2,11cm. In addition, this antenna provides the following results: reflection co-efficient S11=-26,59dB, bandwidth BW=0,12GHz, gain G=5,6, directivity D=5,8dB, and efficiency η=96,55 %
