Abstract:	本論文所提出之較短距離將天線封包相關係數（Envelope Correlation Coefficient）最佳化設計，突破以往認為提升天線封包相關係數所使用增加天線之間的距離或改變電磁耦合係數的做法。首先，透過模擬軟體HFFS（High Frequency Structure Simulator）找出最佳饋入和短路點，並以倒F型平板天線（Planar Inverted-F Antenna, PIFA）作為天線主架構來設計出符合1.8GHz頻段，最後透過實作驗證此設計方法能夠在固定饋入、短路點及頻段下較短距離內擁有最佳天線封包相關係數。;In this thesis, the shorter distance of the antenna ECC（Envelope Correlation Coefficient） optimized design is proposed, breaking the past concept of enhancing the ECC antenna by increasing the distance between the antennas or changing the electromagnetic coupling coefficient approach. First, through simulation software HFFS（High Frequency Structure Simulator）, we find the best feed and short pin, and the PIFA（Planar Inverted-F Antenna）is referred as the primary architecture reference design to meet the 1.8GHz band. Finally, for the verification of this design method is made through the feed, short pin and the band ECC which offers the best values in the shorter distance between the antennas.
