| 摘要: |
| 本文从研究微带天线的积分方程出发,推导了从积分方程组到矩阵方程的全部公式,特别是对奇异积分进行了处理。提出了任意形状微带天线贴片及其附近表面的分块法,及矩形和三角形分块的自耦和互耦的计算方法,从而解决了用矩量法分析任意形状微带天线的问题。进一步利用几何绕射理论,考虑载体的绕射场影响,使载体上天线辐射方向图的计算结果与实验结果更吻合。计算了一种很有实用价值的特殊形状——双扇形微带天线的辐射方向图,并同实验结果作了比较。 |

| Abstract: |
| In the paper, the derivation of all formula from integral equation group
to a matrix equation is replenished, and especially the problem of singular integral
is handled. The surface segmentation method over and near the conducting patch,
and the method for caculating the self and mutual couplings of rectangular and
triangular segments are proposed, thereby the problem of microstrip antennas of
arbitrary shapes is solved using the moment method. The effect of the diffraction
field of carrier by GTD is further considered, so that the calculated radiation pattern
of microstrip antennas on carrier is more agreed with experimental results. The
farfield results of valuable double fan-shaped microstrip antenna of special shape
are computed and comparaed with the measured data. |
