High performance antenna array architectures

随着无线通信系统的发展和复杂性的增长，对作为这些系统的关键部件的天线的要求也在不断提高。 因此，天线阵列具有主要的技术兴趣，因为它们能够被动地提高链路增益，减少干扰，并响应于环境的变化动态地调整它们的辐射图案。 然而，以其传统形式实现的天线阵列在所需的硬件量方面非常昂贵，特别是在利用许多天线元件的高增益天线阵列中。 从性能的角度来看，需要进行新的研究来提高天线阵列的增益、功率处理和带宽，以满足新无线系统的需求和经济约束。

As wireless communications systems have evolved and grown in complexity, so have the demands they place on the antenna which is a critical component of these systems. As such, antenna arrays are of major technological interest because of their ability to passively improve link gain, reduce interference, and dynamically adjust their radiation patterns in response to changes in the environment. However, implemented in their traditional form, antenna arrays are very costly in terms of the amount of hardware required, particularly in high gain antenna arrays utilizing many antenna elements. From a performance perspective, new research is needed to improve the gain, power-handling, and bandwidth of antenna arrays to meet the needs and economical constraints of new wireless systems.
