摘要

The performance assessment and analysis of a wearable microstrip antenna based on high permeability material substrate in head imaging system is presented. The antenna is designed on polymer RTV6166-iron oxide substrate with relative permittivity and relative permeability of 3 and 5, respectively. The antenna consists of an inset-fed microstrip rectangular patch with dimensions of 44×72 mm, connected to 50 Ω feed. To evaluate the effect of the permeability in electromagnetic head imagining, the antenna is benchmarked against another similarly geometrized polymer RTV6166 based with unity permeability. Numerical simulations using CST Microwave Studio for both antennas are performed in free space and on a 3D human head model. The simulations results show that the antenna with high permeability exhibits better reflection coefficient (S
