摘要

這論文設計的陣列天線是屬於小型的陣列天線，因為考慮到製作上的困難點以及無反射實驗室空間大小的限制，因此製作小型的陣列天線。
這研究操作的頻段為7.9GHz、10.9GHz、16GHz，而最終目的在於可以達到三個頻段分別形成獨立的波束，也就是說三個頻段的波束方向可以不一樣，在設計時的困難點在於需要考慮每個頻段之間的天線是否會互相影響，間接影響波束是否可以獨立成型。
三個頻段分別的波束方向以及增益大小，15度、15度、10度以及16.76dBi 、18.82dBi、19.54dBi，在模擬與量測之間幾乎接近，但會有些許的誤差，原因在於量測時校正的誤差以及使用黏膠的參數誤差，不過大致上是幾乎一致的。

In this thesis, this reflectarray antenna is a small array antenna, because of the difficulty in fabrication and the limitation of the size of the chamber space.
The frequency band of this research operation is 7.9 GHz, 10.9 GHz, and 16 GHz, and the ultimate goal is to form separate beam for each of three frequency bands, that is, the beam directions of the three frequency bands can be different, and the difficulty in design is that we must consider whether the antennas between each frequency band will affect each other, and indirectly affect whether the beams can be formed independently.
The beam direction and gain of the three frequency bands is 15 degrees, 15 degrees, 10 degrees, and 16.76dBi, 18.82dBi, 19.54dBi. There are almost close between the simulation and the measurement, but there is a little bit of error, because of the error of correction and the parameter error of the glue, however, they are almost identical.
