摘　　要：为了使RFID在物流业中有更好的应用,分别采用双点馈电和结构变形的方法,设计并仿真了双馈电点圆形贴片天线和宽带双极化全向变形倒L天线。经HFSS仿真得出,在中心频率点为2.85 GHz时,双馈电点圆形贴片天线获得了双极化,变形倒L天线获得了32.3%(VSWR<2)的宽带。In order to achieve a faster application of RFID in the logistics industry,the dual feed point circular patch antenna and broadband dual-polarized omni-directional deformation inverted L antenna were designed with the methods of dual point feed and structural deformation.During the simulation with HFSS,when the center frequency was 2.85GHz,the dual feed point circular patch antenna obtained dual polarization,deformation inverted L antenna got a broadband of 32.3%（VSWR 2）.
