Outline of Final Research Achievements |
For the disaster prevention, the helmet antenna has been required to achieve the hands-free operation. The required performances for the helmet antenna are not only the low-profile and small configuration but also the suppression of the radiation toward a human head. Firstly, the crank-type folded dipole antenna on conductor ring with L slit was proposed. The suppression of radiation toward the human head and impedance matching can be achieved simultaneously. Next, novel antenna design procedure was proposed. The characteristic mode of double hemispherical conductor shell was analyzed, and the suitable feeding point was selected for the characteristic mode. Finally, the unit cell structure composed of multi-layer ceramic capacitors was designed to achieve the artificial magnetic conductor.
