Compact dual-mode antenna for body-centric wireless communications

摘要

Body-centric wireless communications (BCWCs) have recently become an active area of research because of many applications such as medical care systems, identification systems and entertainment. In this review paper, a compact dual-mode antenna for on-body and off-body communications is presented. In on-body mode, the antenna performs as an electrode which generates electric field distribution at 10 MHz. Therefore, significant low-power consumption can be realized for on-body communications. In off-body mode, the antenna radiates at the 2.45 GHz ISM band to communicate with an external device.
