Summary:
In recent years, wireless body area network (WBAN) using a device that includes a radio terminal placed in or on the body has received a lot of attention [1]. It has the potential to provide various ubiquitous services for medical, health care, entertainment, and security. To analytically investigate the transmission mechanism of a wearable device for on-body wireless communications, we derive and discuss exact solutions represented by eigenfunction solutions for the scattered electromagnetic fields. We then consider the propagation characteristic of the wearable device attached to a human body by approximating the body to a dielectric circular cylinder. First, we derive the frequency-domain integral representations of the eigenfunction solutions for the scattered electric fields. We analytically obtain the transmission coefficient between the transmitting and receiving antennas in the vicinity of the dielectric cylinder. Then, we evaluate the influence of the infinite dielectric circular cylinder on the BER (Bit Error Rate) performance for the digital wireless communications using the industrial, scientific and medical (ISM) band of 900-928 MHZ. Additionally, we discuss the measured results of the transmission coefficient in the vicinity of the 2/3-muscle equivalent phantom body for comparison with the calculated results.
