| 摘 要： | 本文用积分方程法计算了角馈微带天线的输入阻抗，并分析了不同参数对输入阻抗的影响．对求解过程中遇到的奇异振荡函数积分，采用渐进抽取技术，将二维无限区间的积分转化为一维有限区间的定积分．与传统的计算方法相比，本文方法所用的计算时间大为缩短．所得计算结果与实验结果相当一致

| Abstract: | The input impedance of corner fed microstrip antenna is calculated with the aid of the integral equation method and the effect of various parameters are investigated. For the infinite double integrals involved in the problem, an effective asymptotic extraction technique is applied, which transforms the infinite double integrals of singular oscillating functions into the finite one dimensional integrals. The proposed method reduces the computation time notably. The calcula ted results agree with the experimental results. |
