摘要
首先分析了端射相控阵列的特殊性,以及传统理想点源阵描述端射阵列的不足。然后以八木天线为原型设计了平板端射天线。为了提高增益和方向性,把四个平板端射天线单元在端射方向上排列。通过调整单元之间的间距和馈电相位,形成特殊的相控阵,达到了比较好的组阵效果。经过仿真和实际加工测试,认为这种天线结构优于传统的组阵形式。
In this paper,the particularity of end-fire phased antenna array and the disadvantages of traditional ideal point source array are analyzed.Plate end-fire antenna is designed according to Yagi-Uda antenna.To improve the directivity and gain,the four units of plate end-fire antennas are arranged in the direction of end-fire.By adjusting the units space and feed phase,a special phased array can be achieved with better arrangement of array effect.From the simulations and practical measurement,the conclusion can be made that the end-fire antenna structure has superiority over the traditional group structure.
