摘要

本文对卫星通信用38ghz发射阵列天线进行了数学分析。在本研究中，工作在基模下的矩形波导被认为是单位单元元件，因为通过改变波导的长度可以很容易地改变其传输幅度和相位。首先研究了单元件的传输和辐射特性，并推导了场图的计算公式。结果被外推到一个交替放置的波导阵列。给出了单波束天线的样例设计，并利用该公式绘制了e面和h面方向图。

Mathematical analysis and design of a 38 GHz waveguide transmitarray antenna

This study is a mathematical analysis of a 38 GHz transmitarray antenna for satellite communications. In this work rectangular waveguides operating in fundamental mode are considered as the unit cell elements as their transmission magnitudes and phases can be altered easily by changing the length of the waveguides. First the transmission and radiation characteristics of a single element is studied and a formulation for the field patterns is derived. The results are extrapolated to an array of alternately positioned waveguides. A sample design of a single beam antenna is provided and the E-plane and H-plane patterns are plotted using the formulations.
