摘要
本文介绍了一种单向性二元阵,探讨了其在基阵小型化中应用的可能性,分析了影响这种阵单指向性的主要因素。经过理论分析和实测数据验证,此阵结构简单,性能稳定,能形成良好的心脏形指向性图,适合于低频条件下使用。
This paper presents a kind of two-element array, discusses its possibility of being used for array miniaturization and analyses the main factors for influencing its unilateral directivity. Theoretical analysis and experimental survey verify that this kind of array is of simple structure, steady performance, can form a good heart-shape directivity. It is suitable for low frequency condition.
