摘要
设计了一种能与服装完全共形的柔性微带天线,天线材料采用常规的毛毡和铜箔,经简单的加工制作实现了良好的性能。对天线在平放和弯曲条件下的性能进行了测试,测试结果表明:该天线在沿H面弯曲时谐振频率、带宽、辐射方向图变化很小;基于人体健康的考虑,用HFSS软件对天线的SAR(Specific Absorption Rate)进行了仿真,结果表明该天线的SAR非常小,仅为0.048。该天线具有重量轻、结构简单、低SAR等特点,已被用于实际的穿戴天线阵列,能够满足穿戴系统中无线通信系统的要求。
In this paper,a flexible microstrip patch antenna which can conformal with the garment is designed. The antenna structures are made from common felt fabric and copper foil tape. A simple manual cutting fabrication method can provide a satisfactory solution. The performance of the antenna under flat condition and bent conditions are measured. Compared with flat,the resonance frequency,bandwidth and radiation pattern for H-plane bend changed little. Regarding the health effects of radiation,the Specific Absorption Rate( SAR) of the presented antenna has been simulated using HFSS and its value is just 0. 048. The designed antenna has the advantages of light weight,easy manufactured,low SAR,and was used in the wearable array antennas. The array antennas can meet the requirements of the wireless communications in wearable system.
