摘要

本文研制了两种用于电子束扫描系统的毫米波平面阵列天线。在水平面阵列信号处理中，水平布置若干垂直长的子阵列用于波束形成。另一方面，在行波设计中发展了垂直长子阵列。该行波馈电系统在毫米波频段具有结构简单、运行损耗低的优点。为电子束扫描系统的子阵列设计了波导天线和微带天线。本文讨论了用于波束扫描系统的微带天线和波导天线的特点和优点。

Planar array antennas for sub-arrays of electronic beam-scanning systems in millimeter-wave band

Two types of millimeter-wave planar array antennas for electronic beam-scanning systems are developed in this work. Several vertically-long sub-arrays are arranged horizontally for beam forming in array signal processing of horizontal plane. On the other hand, the vertically-long sub-arrays are developed in travelling-wave design. The travelling-wave feeding system is advantageous for simple configuration and low-loss operation in millimeter-wave band. Waveguide antennas and microstrip antennas are developed for sub-arrays of electronic beam-scanning systems. Features and advantages of microstrip antennas and waveguide antennas designed for beam-scanning systems are discussed in this paper.
