Abstract
Recently, radio wave technologies are applying for human health care such as a capsule endoscopy and a hyperthermia. As another application, radio wave is planning to be used in seawater radio communication. At human body and seawater applications, a small size antenna is suitable. So, the normal mode helical antenna (NMHA) that has high efficiency at small size is selected. As for performance understanding, electromagnetic simulation tool is effective. The important subject in antenna application is to clarify the radio wave communication link budget in the dielectric material environment. In this paper, based on electromagnetic simulation results of antenna and radio propagation in the human body and seawater conditions, analytical understanding of antenna performance and radio propagation mechanism is conducted. Through this study, analytical equations for antenna performance and radio wave propagation are derived. The effectiveness of derived equations are ensured through comparison with simulation results.
