摘　　要：调谐双环天线是美国ＣＯＤＡＲ海态雷达探测天线的基本组成单元，适用带宽为２～３０ＭＨｚ．利用矩量法，结合网络理论，推导出其调谐电容和电流分布的计算公式，计算结果与有关文献实际测量的结果相符合．Tunable dual loop antenna, which serves as the basic component for the antenna of the American sea state radar CODAR, is applicable within a relatively wide band of 2￣30 MHz. Moment method combined with network theory is used in this paper to calculate the tuning capacitor of dual loop antenna when impedence matching condition is satisfied. The result shows perfect comformity with the actual measurement decribed in corresponding reference.
