平面微波天线的研究

Studies on the Flat Profile Microwave Antennas

提出了一种可实现高增益的平面微波天线单馈点背腔环形隙缝天线阵，对单环和双环情况进行了较为深入的理论分析和探讨，应用矩量法计算出了单环和双环情况下的口径场分布、方向图和增益．实验结果表明，理论与实际吻合得较好．

A flat profile antenna capable of attaining high gaina cavity backed annular slot array being excited by a coaxial line is presented.Theoretical analysis and discussion of both single and double annular slots array are carried out in detail.The electric field distributions at the aperture surface, directional patterns and gains are calculated via the moment method .The experiments are in good agreement with the theory.
