為因應下世代低軌道衛星行動通訊，毫米波相關的技術發展日漸重要，然而受限於毫米波頻率之傳播損耗較大，其通訊鏈路適合在直視波環境下傳播，並且需要具高增益之大型陣列天線，才得以獲得高吞吐量之寬頻通訊效能，此外還有射頻元件不易取得、價錢昂貴、訊號走線之耦合效應、以及隔離方式等因素在系統規劃上與大型陣列天線設計仍然面臨一些考驗。
本研究為多天線智慧轉傳面板，工作環境設定為室外與室內之間的窗戶玻璃作為轉傳路徑。此系統架構區分為波束成形陣列天線、訊號轉傳及無線充電及三個區塊。首先以Ku頻帶之毫米波大型陣列天線與饋入網路進行訊號收發，並以3對8羅曼透鏡矩陣電路進行波束成形切換。波束成形電路利用1對3開關IC及耦合器IC進行路徑選擇。接著，在玻璃兩側設計對稱之濾波耦合器作為兩側的轉傳通道。最後以Qi低頻電磁感應線圈作為室內電力對室外主動IC所需之偏壓電源，使得室內與室外面板得以進行有效的轉傳。

In response to the next generation of mobile communications, the development of millimeter-wave-related technologies is becoming more and more important. However, due to the large propagation loss of millimeter-wave frequencies, the communication link must be propagated in a direct-line wave environment, and a large-scale array antenna with high gain is required to obtain high-throughput broadband communication performance.
Therefore, in this study, a coupling circuit is designed as a transmission channel for indoor and outdoor communication. Signals transfer through an antenna array of Ku-band millimeter-wave and a feeding network. In addition, a low-frequency electromagnetic coil is needed, which used as the Qi power supply for the indoor power to active the outdoor IC, so that the antenna array and the feeding network can be beamformed and switched to improve the communication performance of the system.
