Abstract
Understanding the near-field distribution of antennas has become more significant since it directly effects radiation performance, energy absorption, and safety in current wireless applications, especially when antennas operate close to the human body. This research explores a Meander Line Antenna (MLA)’s electric field patterns within in-body contexts, emphasizing propagation loss, energy conservation, and electric field deterioration in different physiological tissues. This investigation examines the process of signal weakening in embedded antenna use by assessing the variations in electric field strengths among Muscular tissue, skin, and fatty layers at diverse conductivity levels. By utilizing results from FEKO simulations, the research demonstrates the absorption losses associated with the electric field distribution across tissue surfaces. The findings indicate these tissue components exhibiting higher electrical conductance, such as muscle and skin, experience faster degradation when subjected to electric fields compared to fat, which possess lower dielectric constant. These results provide crucial insights into effectively optimizing MLA structure for medical purposes, ensuring reliable wireless signal transfer in physiological environments.
