摘要:
The described technology uses a dual circularly polarized panel antenna and equal amplitude variable phase control between the two circularly polarized components to achieve a rotatable linear polarization tracking system. An example antenna system includes a plurality of antenna elements that include a plurality of polarization transducers to generate a first signal component and a second signal component from a received wave. A polarization control network applies a phase difference based on an orientation of the linear polarization of the wave with respect to the antenna system between the signal components to generate adjusted signal components. The polarization control network combines the adjusted signal components to form a composite signal that corresponds to the linear polarization of the wave. Linearly polarized transmit and receive signals may be co-polarized or cross-polarized.
摘要(中):
所描述的技术使用双圆偏振面板天线和两个圆偏振分量之间的等幅度可变相位控制,以实现可旋转的线性偏振跟踪系统。 示例性天线系统包括多个天线元件,其包括多个偏振换能器以从接收波产生第一信号分量和第二信号分量。 偏振控制网络基于相对于信号分量之间的天线系统的波的线性偏振的取向来施加相位差,以产生经调整的信号分量。 偏振控制网络将调整的信号分量组合以形成对应于波的线偏振的复合信号。 线偏振的发射和接收信号可以是共极化或交叉极化的。
