摘要
运用矩量法和无限周期法,分析了圆形微带阵列天线的电磁散射特性。利用无限周期阵列的解近似计算了截断阵列的散射截面。数值结果表明端接阻抗负载对阵列天线散射特性影响与入射平面波方向、极化以及覆盖介质层厚度有关。
The scattering characteristics of circular microstrip array antennas are analyzed,Using mo- ment method and infinite period approach.An approximate solution of radar cross section for the truncated array is obtained based on the exact solution of the corresponding infinite array.The numerical results show that the effect of terminating impedance load on scattering characteristics depends upon the direction and polarization of the incident wave and upon the thick ness of the dielectric coating.
