天线阵列已被证明是一种非常有前途的技术，用于高速无线网络，并预计在未来的无线通信系统中必不可少的组件。本文综述了将来自不同接收阵元的信号组合在一起以及将信号分离到不同发射阵元的电路技术，重点是硅基解决方案。它还审查电路技术，以控制来自/到每个阵列元件的信号的相位和幅度，使得来自这些阵列元件的信号可以以期望的方式组合和分离，以实现高数据速率通信以及干扰管理。
Antenna arrays have been demonstrated as a very promising technique for high-speed wireless networks, and are anticipated to be indispensable components in future wireless communication systems. This review paper presents an overview of the circuit techniques on combining signals from different receive array elements as well as splitting signals to different transmit array elements with emphasis on silicon-based solutions. It also reviews circuit techniques to control the phase and the amplitude of signals from/to each array element such that signals from those array elements can be combined and split in a desired manner for achieving high data rate communications as well as interference management.
