分析了单元间距较大的小型天线阵的基本特性，探讨了这种天线阵的设计方法，设计了一个小型大间距八木阵，试验结果表明，这种天线阵增益高，波瓣性能好，是米波警戒雷达天线小型化的有效途径之一。

This paper analyses the basic characteristics of the miniaturized array with large elements distance, and discusses the design of the array. A Yagi antenna array was designed, and the test results show the array has better performances. By the design method, the meter wave warning radar array can be miniaturized efficiently.
