【摘要】 本文介绍了一种新型双层印刷振子天线。天线一面刻蚀平面偶极子单元,另一面刻蚀圆弧短路枝节,并通过穿孔连接。天线下方采用平面反射器形成定向辐射,属于剖面天线。文中对天线进行了详细的参数分析,并进行仿真验证。仿真验证了其在整个工作频带内具有良好的超宽带特性。由于天线的尺寸只有32mmx23.2mm,剖面高为16mm,因此该天线在无线通信,卫星通信和移动通信中具有广阔的应用前景。更多还原

【Abstract】 This paper describes a new double-layer printed dipole antenna. One side of the antenna etches planar dipole units,the other side of it etches arc-shaped short circuits,and connect them with perforations. There is a planar reflector below the antenna to form directional radiation,and the whole antenna belongs to profile antenna.The paper gives a detailed analysis of the antenna parameters,and verified it through simulation. The simulation proves that this antenna has good characteristics of UWB within the entire bandwidth. The size of the antenna is only 32 mmx23.2 mm,and the height of the profile is 16 mm,Therefore,this antenna has broad application prospects in wireless communications,satellite and mobile communications.更多还原
