【摘要】 为了提高端射天线的方向性,对其进行组阵成为必然。本文为了讨论方向图乘积定理在端射天线阵设计中的有效性,以平板端射天线为阵元,对轴向、侧向两种组阵方式下端射天线阵方向图的理论解与CST仿真解进行了对比与分析。总结了方向图乘积定理在此端射阵中的适用条件,并提出一种缩短侧向单元间距的设想。更多还原

【Abstract】 In this paper,the validity of pattern multiplication theorem in the endfire antenna array designing is discussed.Plate endfire antenna is adopted as the array element,and the arrays are respectively arranged along endfire direction and broadside direction.The theoretic results with pattern multiplication and simulating results from CST are compared and analyzed.The conditions of pattern multiplication’s application in endfire array are summarized,and an idea is put forward to reduce the space along the broadside direction.更多还原
