本論文提出一種由陣列天線和RF相移器以及開路終端結合所組成的可重構智慧表面(RIS)。其原理為輻射陣列天線接收訊號，透過相移器進行相位調製並利用開路端子進行全反射，反射至接收端接收訊號。該可重構智慧表面應用於3.4至3.6 GHz，其中陣列天線部分設計為微帶貼片天線，操作範圍為3.4至3.6 GHz，中心頻率為3.5 GHz，天線採用FR4基板製作，有效控制製作成本；相移器部分則採用商用晶片HMC928LP5E以及MAPS-01044。相對於其他研究者所提出的RIS架構，其具有架構方便且靈活組裝的優勢。
本論文進行該可重構智慧表面的可行性測試並實際製作，透過架設自動化量測平台量測信號通道中的能量強度以及訊雜比，驗證本論文所提出架構帶來之效果。

This paper proposes a reconfigurable intelligent surface (RIS) composed of an array antenna, RF phase shifters and open-circuit terminals. The principle is that the radiating array antenna receives the signal, modulates the phase through the phase shifter, uses the open terminal for total reflection, and the receiver receives the signal which was modulated through the ris.The ris is applied to 3.4 to 3.6 GHz, in which the array antenna part is designed as a microstrip patch antenna, the operating range is 3.4 to 3.6 GHz, the center frequency is 3.5 GHz, and the antenna is made of FR4 substrate, which can effectively control the production cost; The shifter part uses commercial chips HMC928LP5E and MAPS-01044. The ris compared with the RIS architecture proposed by other researchers, it has the advantages of convenient architecture and flexible assembly.
In this paper, the ris architecture is made and the feasibility test of the ris is carried out . By setting up an automatic measurement platform to measure the energy intensity and signal-to-noise ratio in the signal channel, the effect of the proposed architecture is verified.
