Study of a wideband high data rate implantable antenna for cortical visual prosthesis #BCI

Study of a wideband high data rate implantable antenna for cortical visual prosthesis - Scientific Reports
A compact wideband high data rate implantable antenna is designed for cortical visual prosthesis devices. In order to achieve high data rate, a metamaterial array with negative permeability is formed by loading complementary open resonant rings to reduce the resonant frequency of the antenna and produce circular polarization characteristics. By introducing a meandering structure around the radiation unit, the current path on the antenna surface can be increased, further optimizing the impedance…
