Electrical Performances of Meander Line Antenna in Fat Phantom

The meander line antenna (MLA) was employed in small-sized antenna applications. To obtain high antenna efficiency, the self-resonant structure is important. In this paper, the electrical performance of MLA in a human body is clarified. Through electromagnetic (EM) simulations, the self-resonant structure, input impedance, and VSWR characteristics are obtained. In order to measure electrical performance, the human body phantom of fat tissue is fabricated. At the condition of MLA inside the phantom, input impedance and VSWR characteristics are measured. Good agreement of simulated and measured results is ensured.
