【摘要】 本文提出一种工作于体外模式的可穿戴高增益毫米波定向天线。天线应用八木天线的原理并结合电磁带隙(EBG)结构,覆盖60GHz ISM频段,实现了9.6 GHz(15.4%)的带宽和10.7 dBi的增益。在57GHz～64GHz频段内,天线性能稳定,增益波动不超过1.3 dBi,辐射效率稳定在80%以上。EBG结构的引入改善了天线的背向辐射和提高了前后比,确保了人体穿戴的安全性。通过对人体简化模型的仿真,该天线的性能基本不受人体的影响。更多还原

【Abstract】 In this paper,a wearable high-gain millimeter wave directional antenna working in Off-body is proposed.The antenna integrated with electromagnetic bandgap(EBG) structure applies the principle of Yagi-Uda antenna.At 60 GHz,the design achieves a bandwidth of 9.6 GHz(15.4%) and a gain of 10.7 dBi over the entire ISM band.In the 57-64 GHz band,its performance is stable.The gain fluctuation does not exceed 1.3 dBi,and the radiation efficiency is higher than 80%.Applying EBG structure for design helps to reduce back radiation and improve FBR,which ensures the safety of human wear.Through the simulation of the human phantom,the performance of this antenna is rarely affected by the human body.更多还原
