摘要

本篇論文提出一個新的架構『利用可改變尺寸的金屬貼片開槽來控制相位變化做為天線單體，進而製造反射陣列天線（RVSPS）』。這個新架構可以改善之前文獻所記載的『利用可改變尺寸的金屬貼片製造反射陣列天線(RVSP)』的相位曲線，使得相位曲線較為線性。
經由實驗得知，新的反射陣列天線架構在11.4GHz有最大的增益24.25dB、1.5dB增益頻寬19.3%、天線孔隙效益31.48%而且正交極化也小於25dB。

This thesis demonstrates a new configuration of reflectarray using variable size patch with slot (RVSPS) as the construction element. This configuration improves phase curve of the reflectarray using variable size patch (RVSP) in FR4 material. RVSPS has a more lineaer phase curve in comparison with that of the RVSP.
Experimental results of RVSPS showed that the maximum gain is 24.45dB at 11.4GHz. It has a 1.5-dB gain bandwidth of 19.3%. The aperture efficiency is 31.48% and the cross-polarization level is bellow around 25dB.
