  • 本論文係針對四款高速連接器進行完整的分析,第一款高速連接器為通用匯流排USB3.0連接器,USB3.0連接器數據傳輸數率為5 Gbps,第二款高速連接器為雙層小封裝熱插拔收發器SFP連接器,此款SFP連接器為2×1 SFP連接器數據傳輸數率為4.25 Gbps,第三款高速連接器為1×1SFP連接器,此款SFP連接器為單層SFP連接器數據傳輸數率為4.25 Gbps,單層與雙層SFP連接器於規範中定義大致相同,第四款高速連接器為1×1 SFP+連接器,此款SFP+連接器輔以單層SFP連接器修改而成其數據傳輸數率為16 Gbps,並可向下支援至8 Gbps;本文利用電磁模擬軟體分析高速連接器之差模阻抗,並輔以時域反射儀量測驗證之,其模擬與實測趨勢大致相符,並量測連接器之串音干擾與眼圖;本文提出調整塑膠本體之介電常數與調整端子尺寸,使高速連接器之差模阻抗符合規範標準。
    同時本論文針對應用於筆記型電腦之WWAN倒F天線設計,其輔以簡單之架構設計一款倒F天線頻帶符合GSM850/900/1800/1900/UMTS等應用之頻段;本文提出之天線體積小,且此天線具備近似全向性場型與良好的輻射效率,而基本使用廉價的FR4搭配印刷電路技術,故可降低製作之成本與製程之複雜度,並易於整合筆記電腦內,具有相當高之商業價值。


    This thesis proposes four kinds of high speed connectors analysis and design.
    The first design is about USB3.0 connector and the data rate is 5 Gbps. The second design is about double-decker small form-factor pluggable transceiver (SFP) connector and the data rate is 4.25 Gbps. The third design is about single layer SFP connector and the data rate is 4.25 Gbps. The fourth high-speed connector is 1×1 SFP + connector, and it achieved by by adjusting 1×1 SFP connector, and the data rate is 16 Gbps. In the specification, the single layer and double-decker defined in the same. In this thesis an electromagnetic solver has been used to analyze the characteristic impedance and other electrical properties, and the experimental results are performed using the time-domain reflectometry (TDR). Good agreement between the simulated and measured results is obtained. Eventually, the thesis also investigates a manner to increase the dielectric constant of the insulator and adjustment connector terminal size, so that the impedance standards can be well matched with our connector design.
    Also, this thesis proposes a miniaturized inverted-F antenna for laptop computer application and it operates in the WWAN band. The antenna uses simple structure to resonate five operating band of GSM850/900/1800/1900/UMTS. This antenna designs feature not only a small size but also good radiation performance. Consequently, the proposed designs fabricated on FR4 substrate to lower the cost are well suitable for integration into the laptop computers for practical applications.
