圆形极化的辨别出现在许多天线的应用。一条赔偿途径基于多层的电影结构被建议改进块港口的二个垂直模式的大小的轴的比率。目标是拓宽有轴的比率的放射的 beamwidth 不到 3 dB 并且因此在接收装置减少复杂性。一个转移矩阵方法被开发代表多层的电影并且描绘它的表演。用高频率结构模拟器的模拟证明作为一个例子，穿过的偶极子能在半导体 Manufact 完成超过 30lemented 的 beamwidth 吗？？

英文摘要：

Circular-polarization discrimination appears in many antennas＇ applications. A compensation approach based on multilayer film structure is proposed to improve the axial ratio of the magnitude of the two perpendicular modes of the lump ports. The goal is to widen the beamwidth of radiation that has an axial ratio less than 3 dB and thus reducing the complexity at the receiver. A transfer matrix method was developed to represent the multilayer film and characterize its performance. Simulation using high frequency structure simulator shows that a crossed dipole, as an example, can achieve a beamwidth of more than 30° at the frequency of 12.45 GHz after compensation. Finally, conclusions and future work about this compensation method are presented.
