【摘要】 论述了双对数周期偶极天线扇形阵的设计方法,利用IE3D软件对单个对数周期偶极天线(LPDA)和双对数周期偶极天线扇形阵进行了优化仿真分析,并研制了天线实物样机,同时对该天线的电性能进行了测量。测量结果表明,该双对数周期偶极天线扇形阵具有宽带、高增益、小型化等特点,进而说明该设计方法是行之有效的。更多还原

【Abstract】 The design method of fan-shaped array constructed by dual log-periodic dipole antennas is presented.A single log-periodic dipole antenna(LPDA)and the fan-shaped array are simulated and optimized by commercial EDA software IE3D.Then,a sample antenna is made and its electrical parameters are measured.The measured results show that the fan-shaped array is of wide band,high gain and compact dimension,and this means the design ethod is valid.更多还原
