目前,许多研究中心正在研究用间隙式微波天线阵列加垫系统(IMMAH)作为一种治疗人体不同部位的肿瘤。本文从理论和实验两个方面,对肌肉模型中工作于915MHz频率的单个孤立天线的特定吸收率(SAR.W/kg)的分布进行探讨。发现随着测量点温度的提高,SAR减小。这些同轴天线直径为1~2mm。长发为5~10cm。结果表明,偶极天线的长度小于它们的谐振长度时,偶极天线与谐振天线相比具有一特性上更大的动态
At present, many research centers are studying the use of interstitial microwave antenna array padding system (IMMAH) as a treatment of different parts of the body of the tumor. In this paper, we discuss the distribution of the specific absorption rate (SAR.W / kg) of a single isolated antenna operating in the muscle model at a frequency of 915 MHz, both theoretically and experimentally. It is found that the SAR decreases as the temperature of the measuring point increases. The coaxial antenna diameter of 1 ~ 2mm. Long hair is 5 ~ 10cm. The results show that when dipole antennas are shorter than their resonant length, the dipole antenna has a much larger dynamic behavior than the resonant antenna
