Abstract

In this paper, a body-worn planar monopole antenna is proposed for body-centric wireless communications systems (BWCS) working at the frequency around 2.45 GHz. The effect of human body in the near vicinity of the antenna on the antenna performance is also investigated. Based on the body-worn monopole antenna, a simple body-worn MIMO system is developed to improve the capacity of BWCS. The effect of mutual coupling between elements on capacity is also considered. The studies show that the capacity of data transmission is improved when MIMO system is adopted.
