Abstract
A planar monopole antenna in ISM(2.4 GHz)band is proposed in this paper.The antenna is omni-directional,and the echo loss ratio is less than-15 dB in the frequency band ranging from 2.23 GHz to 2.84 GHz.The model of simulating elec-tromagnetic safety environment is established,and the simulation model of human body structure and radiation boundary are estab-lished.Finally,the specific absorptivity and the maximum electric field of the 2.4 GHz frequency point are simulated and analyzed,coupled with the transient thermal module,and the temperature rises of 6 minutes and 30 minutes are calculated,and the safety assessment is carried out with the electromagnetic exposure protection guidelines formulated by the International Commission on Non-Ionizing Radiation Protection(ICNIRP).The results show that the specific absorptivity,electric field intensity and temperature rise of the antenna to the brain and heart are far less than the safety limit and will not cause harm to health.关键词
