摘要

本文综述了与功率放大器(pa)共同设计的有源集成天线的最新进展。举例说明了三种提高输出功率和功率附加效率的策略，即放大器与天线直接匹配、天线谐波反射调谐和天线内多个放大器的功率组合。展望了这些策略在宽扫描相控阵中的应用所面临的挑战。

A Review of PA-Antenna Co-design: Direct Matching, Harmonic Tuning and Power Combining

This article reviews the current state-of-the-art of active-integrated antennas co-designed with power amplifiers (PAs). Three strategies to improve output power and power-added efficiency are described using examples, namely direct matching between PA and antenna, tuning of harmonic reflections in the antenna, and in-antenna power combining from multiple PAs. An outlook is given on the challenges to be faced in the application of these strategies in wide-scanning phased arrays.
