| Abstract(in English) | Helmet antennas have been considered for integrating into the helmet for disaster prevention. To achieve the helmet antenna for low frequency operation, low-profile and small antennas are required to install in the helmet. This paper presents the characteristic mode analysis of the helmet antenna, which is double hemispherical conductor shell, in order to achieve the omni-directional pattern in the horizontal plane. By deleting the weak part of the electric current on the double hemispherical conductor shell, the shape of the folded dipole and inverted-L antenna is achieved the omni-directional pattern in the horizontal plane. |
