摘要

．灾害发生时，在抢险疏散活动中必须佩戴防灾头盔，防止二次灾害的发生。头盔天线作为一种可穿戴式天线得到了广泛的发展。本文研究了半球形导体材料对欧姆损耗的影响。此外，通过实验验证了仿真结果的有效性。为了进一步提高增益，对天线单元的加载位置进行了检测。结果表明，在150 MHz时获得了−2.6 dBi的最大增益和0.07 W/kg的局部比吸收率值。

Helmet-Mounted Inverted-F Antenna at VHF Band

. A helmet for disaster prevention must be worn to prevent secondary disasters in rescue and evacuation activities when a disaster occurs. Helmet antennas have been widely developed as wearable antennas. In this paper, we investigated the effect of ohmic loss due to the material of the hemispherical conductor. In addition, the validity of the simulation results was verified through experiment. The loading position of the antenna element was examined to further improve the gain. As a result, the maximum gain of −2.6 dBi and the local specific absorption rate value of 0.07 W/kg was achieved at 150 MHz.
