Input Impedance Change of Meander Line Antenna in Human Body Conditions

This paper presents the simulation results and evaluates the performance of the meander line antenna (MLA) in human body conditions, comparing different permittivity and conductivity values, including muscle, and fat tissues. The electrical characteristics obtained by simulation, such as input resistance (R
in
), and MLA self-resonant structure are discussed. The theoretical and simulation results are compared for the validation of the simulation environment. The absorption loss is calculated and compared with the simulation results. The input resistance increases when the antenna conductivity increases.
