Abstract

Medical applications are becoming increasingly important for monitoring patients or diagnosing and treating pathologies. They use biological sensors that interact with the human body. Biosensors need to be efficient, reliable, and non-harmful to create trust among users.

Of all the components of a biosensor, the antenna plays a leading role. However, the human body modifies the characteristics of antennas and absorbs most of their radiation. What's more, antennas transmitting within or close to the body are subject to restrictions.

This thesis focused on the development of medical antennas that overcome both standardization restrictions and the adverse effects of the human body on electromagnetic radiation.

In addition to the bibliographical study in the first part, it includes three other parts. The second part is dedicated to the development of two miniature-performance antennas for medical implant and cardiac defibrillator applications, respectively. The third part of our study involved developing three patch antennas for body-worn gadgets and enhancing the performance of the most suitable antenna using metamaterials. In the fourth part of this thesis, a meander antenna was dimensioned for early diagnosis of skin sarcoma by reflection coefficient variation.
