Abstract

This paper presents a weighted-polarization antenna applied to BAN (Body Area Network) on-body communication systems. A primal objective is to achieve the radio link enhancement in both downlink and uplink on-body channels. The proposed antenna obtains an optimum signal level using a weight function considering the BP-XPR (Body Proximity Cross-Polarization Power Ratio) and antenna tilt angle. The results show that the proposed antenna achieved more than a 3-dB improvement of received signal compared with the other types of antennas, such as vertical dipole, horizontal dipole and equal weight combined antennas, regardless of the arm-swing motion and antenna placement, which verifies the effectiveness of the proposed method to enhance BAN on-body radio links.
