| 摘 要： | 本文用矩量法分析了介质加盖矩形微带天线的特性，讨论了收敛性问题和加盖对天线的输入阻抗，辐射效率及增益等的影响，以及已有设计公式的适用性等。结果表明：加盖后天线的阻抗可能上升也可能下降，谐振下降，增益提高，辐射效率可能上升也可能下降，谐振频率的理论计算值与设计公式计算值有时偏差较大，必须用前者。

| Abstract: | In this paper, the method of moment is used to analyze the covered rectangular microstrip antenas, and discussion is made on the computational convergence and the effects of covering on the input impedance, radiation efficiency and gain of the antenna, and the validity of the conventional design formulae. The obtained results show that covering may cause the input impedance and the radiation efficiency to increase or decrease, the resonant frequency to decrease, the gain to be enhanced, the discrepancy between the values of resonant frequency obtained by the method of moment and by the conventional formuae to become significant sometimes. |
