一款基于HFSS仿真的倒F蛇型印制天线

摘要

设计了一种用于2.4 GHz智能无线传感器的倒F蛇型天线,.使用HFSS仿真和设计,根据优化后的天线模型参数,最终设计集成在无线传感器印制电路板上印制天线,使天线可达到最佳的效果.该天线的仿真和实测结果表明,在2.45 GHz的中心工作频率下,回波损耗小于-12dB,带宽约为100 MHz,阻抗50.58+j0.55,满足了IEEE 802.15.4协议的要求.%An inverted F snake antenna for 2.4 GHz smart wireless sensor is designed,. Using HFSS simulation and design, according to the optimized antenna model parameters, the final design integrated on the wireless sensor printed circuit board printed antenna, so that the antenna can achieve the best results. The simulation and measured results show that the return loss is less than -12dB at the center operating frequency of 2.45 GHz, the bandwidth is about 100 MHz, and the impedance 50.58+j0.55 meets the requirements of the IEEE 802.15.4 protocol.
