Design of a Dual-Band Antenna for Wearable Wireless Body Area Network Repeater Systems

Abstract

A dual-band on-body antenna for a wireless body area network repeater system is proposed. The designed dual-band antenna has the radiation directed toward the inside of the human body at MICS band and directed toward the outside at ISM band to transmit information collected from an implanted device to an external monitoring system. In addition, the return loss property of the antenna is insensitive to human body effects by utilizing the epsilon negative zeroth-order resonance property.
