Dual-polarized UWB Implantable Magnetic Dipole Antenna

An dual-polarized implantable magnetic dipole antenna (IMA) for ultra-wideband (UWB: 3.1 - 10.6 GHz) spectrum operation is proposed for biotelemetry usages. The dual-polarized UWB implantable antenna consists of two magnetic dipoles perpendicular to each other, which enables dual-polarized radiation. The radiator is built on a square dielectric material (εr = 6, σ = 0.0005) with a cavity embedded in the appropriate accompanying circuit system. The volume of IMA with biocompatible insulator (PEEK: εr = 3.2, tanδ = 0.01) is 1456mm3. The IMA was numerically optimized using HFSS software with simple multilayer body tissues (skin, fat, and muscle) as the host environment.
