Abstract :
Body-centric wireless communications (BCWCs) have become an active area of research due to their wide range of applications. Therefore, as an interface between the transceiver and the propagation environment, antennas in these systems need to be carefully designed. Moreover, in this paper, we proposed two multi-functional antennas for on-body (10 MHz) and off-body (2.45 GHz ISM band) communications in health monitoring system. In on-body communications, the received voltage and electric-field distribution are analyzed. In addition, in off-body communications, the reflection coefficients and radiation patterns are discussed.
