多頻段5G智慧型手機搭配WiFi 6E的MIMO天線之研究

為了解決Smart phone的問題，作者陳彥銘 這樣論述：

由於科技進步和設計的技術創新，網絡在現在的社會被廣泛用於傳輸各種數據並獲取大量信息。 因此，對網絡帶寬的需求也不斷地持續增加。 隨著5G的發展，加上各種支持物聯網的移動設備也必須配備5G系統，來提升傳輸速度、提高頻寬及資料的傳輸量藉此技術便能做到即時資料傳輸 因此，本文的天線設計加入了5G使用的頻段，同時也融合了WiFi 6E的頻段。本論文提出透過兩根天線組成一個多端口輸入及多端口輸出 (MIMO) 系統，其中主天線位於智能手機的下半部分，分集天線位於智能手機上半部分。本研究的主天線採用平面倒 F 形天線 (PIFA) 設計，分集天線設計也採用平面倒 F 形天線設計。另外，透過多路徑耦合設計

，增加帶寬，減少天線設計時所需要占用的面積，使天線可以安裝在智能手機中。同時加入多分支多路徑，達到多頻段的效果。主天線饋源位置與分集天線饋入源呈現斜對面的狀態，高頻和低頻的設計路徑方向也相反，實現高隔離設計，讓智能手機在使用中具有高吞吐量。主天線和分集天線覆蓋的頻段可以滿足2G (GSM)、3G( WCDMA)、4G (LTE)的全頻段並增加了5th 移動通信（5th Mobile Communication；5G），包括5G nr 頻段（N77、N78、N79）和 WiFi 6E。本文設計的2隻天線的設計模塊不同，因此產生不同的水平極化和垂直極化，以及不同的分極效果。將信號源由網絡分析儀提

供給主、副天線，可以量測出天線本身的工作頻率，並測量主副天線的隔離度。同時，通過天線電波暗室可以測量兩根天線的效率、2D場型圖和3D場型圖。本文設計的天線具有良好的隔離性。天線之間的線性極化和交叉極化非常不同。所有頻段的相關係數（ECC）也可以達到

整合群眾智慧概念之路面品質偵測系統

為了解決Smart phone的問題，作者丁修晨 這樣論述：

為了維護民生及企業用的管線，政府不得不經常進行道路的開挖，但在修補與鋪設的過程中，有可能發生道路工程品質不一與氣候影響等情況，造成路面不平整、高低差等問題的發生，道路的不平整，不管是對機車駕駛還是汽車駕駛，都會影響到行車的體驗，以及機車騎士的安全，每年都能從新聞中看見，因道路顛簸或坑洞所造成的交通意外。機車騎士往往會因為不熟悉路況或是天色影響導致視線不佳，造成駕駛無法確切地得知路面情況，提前避開路面顛簸位置，進而發生危險。 本研究結合群眾智慧概念以及手機三軸加速度計(Accelerometer)的功能進行道路異常的資訊蒐集，在開發異常路面偵測APP的過程中，也同時進行了使用者意

願度的問卷調查，該問卷用於探討該異常路面偵測APP開發後是否會有民眾有意願使用，以及進行異常路面偵測APP的功能調整。本研究除了利用大眾都有的智慧型手機來進行路面偵測的作業，也結合群眾智慧之概念，透過群眾的力量，擴大蒐集資訊的範圍與資訊的準確率。
