| Outline of Final Research Achievements |
The performances of antennas for mobile communications, which are used in vicinity of the human body, have been evaluated employing tissue equivalent phantoms. In these cases, “uniform” tissue equivalent phantoms are mainly employed. However, the uniform phantom is not suitable to evaluate performances of the antenna, which are used inside the human body such as capsular endoscope. Therefore, in this study, a realistic abdomen phantom has been developed. This phantom consists of muscle, lung, heart, liver, stomach, large intestine, and small intestine. In addition, as an example, the antenna for wireless power transmission of capsular endoscope has been developed. Moreover, performances of developed antenna have been investigated by the phantom. From the results, good agreements between calculation and measurement are observed. So, it is considered that the developed phantom is effective for performance evaluation of the antennas, which are used in and around the human body.
