Radiation characteristics of small slot antenna for wristwatch-type pager worn on human body

摘要

In recent years, the demand for compactness in port- able radios has become increasingly stronger. This trend is more significant in pagers, and wristwatch-type pagers have been commercialized. In this article, a small slot antenna to be installed in the watchband is investigated. Since the present antenna is used in close proximity to the Human body, human models for both theoretical and experi- Mental studies are created taking into account the human Body as part of the antenna structure, and the radiation Characteristics of the small slot antenna actually worn on The human body are measured and calculated.
