本論文的目的為驗證在非直視波的無線傳播環境下的無線通道環境控制之可行性研究。考慮到毫米波頻率應用的傳播損耗較大、設計成本以及量測困難度等因素，本論文選擇5.2 GHz的頻帶作為設計目標，轉傳面板的設計是通過對4×4巴特勒矩陣的改良，設計了一個3×4的波束切換電路，目的為產生一個偏移角度為0度的主波束。將3×4波束切換電路結合串列饋入式微帶陣列天線後，主波束產生了±20°和0°的偏移角度。P1饋入時，主波束的增益為7.65dBi，P2饋入時，主波束的增益為8.48dBi，P3饋入時，主波束的增益為7.09dBi。實際量測結果顯示，在未加轉傳面板時，在目標頻率5.2GHz下的穿透係數為-57.975dB；加了轉傳面板後，在目標頻率5.2GHz下的三個轉傳角度(±20°和0°)的穿透係數分別是-46.249dB、-45.439dB、-46.651dB；因此，可以發現加了轉傳面板後，穿透係數整體提升約12dB左右的增益。

This paper aims to verify the feasibility of wireless channel environment control in non-line-of-sight wireless propagation environments. Considering the challenges of millimeter-wave frequency applications, such as high propagation loss, design cost, and measurement difficulties, the study focuses on the 5.2 GHz frequency band. By modifying a 4x4 Butler matrix, a 3x4 beam switching circuit is designed to generate a main beam with a 0° offset angle. When combined with a series-fed microstrip array antenna, the main beam achieves offset angles of ±20° and 0°. The measured results show that the addition of a transfer panel increases the penetration coefficient by approximately 12 dB at 5.2 GHz, indicating an overall gain in wireless communication performance in non-line-of-sight scenarios.
