Design of a triple-band on-body antenna for a biomedical repeater application

A triple-band on-body antenna for a biomedical repeater application is proposed. The designed triple-band antenna has intensified field distribution toward the inside of the human body in the medical implantable communication service band and wireless medical telemetry system band in order to collect vital information from the medical devices located in the human body. To transmit information collected from implanted devices to a monitoring system simultaneously, the proposed antenna has the maximum radiation directed toward the outside in the industrial, scientific and medical band. In addition, the return loss property of the antenna is insensitive to human body effects by utilizing the epsilon negative zeroth-order resonance property.
