Dual-mode wearable antenna for on-/off-body wireless communications

Abstract

Body-Centric Wireless Communications (BCWCs) using wearable wireless devices are received an increasing amount of attention due to wide applications such as medical care system, identification system, smart home and entertainment. In this paper, we proposed a wearable dual-mode (on-/off-body modes) antenna for medical care system. In this paper, electric field distribution is analyzed for the on-body mode and reflection coefficient (S11) and radiation patterns are discussed for the off-body mode.
