National Taiwan University of Science and Technology

設立目標

自92年8月獲教育部補助設立「無線通訊與電磁相容技術研發中心」以來,本中心建置了數座無反射實驗室,具有台灣各大學最為完善之天線量測設施。

這些設備可提供本校及其他單位進行相關技術和產品之研發工作,並建立緊密產學合作研發關係,以達成技術創新的目標。

促進前瞻與創新應用研究,以研發關鍵技術與培育產業界所殷切需求之人才,來提昇產學合作計畫之質與量,並且整合相關資源與人力。

National Taiwan University of Science and Technology

發展現況

本中心已擁有相當完整之天線與微波電路量測系統,並於102年起開始分年建置毫米波量測系統, 來 建立 可 高 達90GHz之完善天線與電路量測系統,期能成為產業研發升級的有力後盾。

與多家公司合作研發無線通訊天線與射頻模組,以研發前端創新應用技術與具競爭力之產品,而多項設計並已進行量產或試量產中。

協助相關業界設計高速連接器,以建立前端應用技術,來提升產品之導入時效與競爭力,而多項設計並已進行量產或試量產中。
