    摘要:

    以磁性材料(JV 5)作为基板,设计双L型结构的微带天线,带宽是普通基板的2倍以上,尺寸缩小了40%。在此基础上引入电磁带隙(EBG)结构,设计了一种基于磁性基板EBG结构的微带天线,该EBG结构采用接地板腐蚀性,即在地板上腐蚀出周期H型和圆形结构,采用电磁仿真软件HFSS14.0进行仿真设计。结果显示,与非磁性材料做基板的微带天线相比,EBG结构磁性材料具有小型化和宽频化突出优点,相对带宽达到10%以上,增益方面略有降低,引入EBG结构后能在一定程度上减小了天线的尺寸同时增大了天线的带宽,改善了天线的增益和辐射特性。

    Abstract:

    The double L shaped slot microstrip antenna is designed by using the magnetic material (JV 5) as substrate. Based on the magnetic material (JV 5) substrate, Double L shaped slot microstrip antenna is designed. The bandwidth is 2 times more than the normal substrate, size reduction of 40%. And then, the electromagnetic band gap (EBG) structure is introduced to design the microstrip antenna based on magnetic base plate EBG structure, the EBG structure uses the joint floor corrosion, namely the cycle H type and circular structures are corroded on the floor. Numerical simulation is performed with HFSS14.0. The results show that comparing with the microstrip antenna based on the non magnetic material substrate, the EBG structure of magnetic material has a prominent advantage of the miniaturization and high speed. The relative bandwidth is up to 10% but the gain is slight reduced. The introduction of the EBG structure can to some extent reduce the size of the antenna while increase the bandwidth of the antenna, and improve the gain and radiation characteristics.
