本論文針對第四代行動通訊系統的需求,分別提出單一天線以及天線陣列相關技術,且除了天線性能表現之外,也進一步探討天線生物相容特性相關規範。一開始我們提出兩項雙寬頻設計技術,且分別以兩項實際能涵蓋LTE/WWAN八頻操作的筆記型電腦天線進行相關說明及討論,並提出相關的技術可以應用於平板電腦天線。接下來則是以LTE/WWAN 與LTE MIMO 天線陣列為主軸,進行隔離度的分析,同時也針對筆記型電腦、平板電腦、手機在機構以及隔離度的異同上做了一系列的討論。最後,則是針對平板電腦相較於筆記型電腦以及手機較不同之Body SAR 量測進行介紹及探討。
In this dissertation, not only the antenna and antenna array design techniques for fourth-generation mobile communication system are proposed, but also the specifications related to antenna bio-compatibility are studied. At first, two dual-wideband design techniques suitable to be applied for laptop computer applications for LTE/WWAN and LTE MIMO operations are proposed. The techniques can also be applied to internal tablet computer antennas. The isolation issues of MIMO antenna array of different mobile communication devices, such as laptop computer, tablet computer, and mobile phone, are then discussed. Finally, an analysis of body SAR for tablet computer applications are given and discussed.
