Numerical Investigations of Implan Meander Line Antenna of Three-Dimensional Human Head Phantom for Brain Machine Interference

Abstract

A novel structure meander line antenna is investigated in this paper for anatomically realistic human head phantom of implantable Brain Machine Interference (BMI) applications. Head phantoms imitating electrical properties of brain tissues and their anatomical configuration are highly requisited for verification of numerous biomedical devices. To approve the analysis of implantable antennas more accurately, simulation is examined using anatomical realistic human head phantom. The main integrity of this antenna specifies to its subtle dimension, flexibility and subordinate thickness that makes it perfectly applicable for implementing inside human head phantom operating ultra-wideband frequency spectrum. Meander line technique is imposed in implantable scenarios. Dimension of the antenna structure is (15.2 * 8.8 * 0.8) mm3, where Roger RO3035 is selected as the substrate material. Copper is selected for Patch material. And the antenna is encapsulated by silicon material for maintaining biocompatibility. Crucial parameters are analyzed such as S11 parameter, Radiation pattern, VSWR, Gain, Efficiency, Directivity, SAR values of the proposed antenna for anatomical realistic human head phantom. This improved design of MLA configuration reducing Specific absorption rate for safety concerns.
