本論文提出一應用於4 x 4 LTE MIMO系統之智慧型手機四天線設計，四天線皆為開槽孔天線且分別配置於手機四側邊，以槽孔基頻模態搭配匹配電路達成寬頻操作，上下短邊雙主天線可涵蓋698~960 MHz，長側邊雙副天線可涵蓋824~960 MHz頻帶，並且長側邊開槽孔天線高度僅1 mm，亦可適用於現今窄邊框手機。雙主天線操作於698~960 MHz可應用於2 x 2 MIMO系統，而全部四天線在824~960 MHz則可應用於4 x 4 MIMO系統，在SNR為20 dB，通道容量可達到 17.6 bps/Hz。除此之外，本論文亦針對使用者手握分析作探討，考量現今使用者不僅以單手直立操作手機，在觀賞影片時更常以雙手橫向操作，因此以不同的手持狀況針對天線輻射效率及通道容量進行研究及討論。

Four LTE MIMO antennas in the smartphone for application in the 4 x 4 MIMO system are presented. The four antennas are based on the open-slot antenna structure and disposed along the short edges and the long side-edges of the smartphone. The two short-edge antennas can cover 698~960 MHz. The two long side-edge antennas have a low profile of only 1-mm ground clearance and can cover 824~960 MHz. The two side-edge antennas are suitable to be disposed in the current narrow-framed smartphone. The two short-edge antennas can be applied in a 2 x 2 LTE MIMO operation in the 698~960 MHz band. On the other hand, the four antennas can be applied in a 4 x 4 LTE MIMO operation in the 824~960 MHz band. The calculated channel capacities of the 4 x 4 LTE MIMO operation can reach about 17.6 bps/Hz at 20-dB signal-to-noise ratio. The effects of user’s hand on the MIMO performance are also studied, and both one-hand data mode and two-hand data mode are considered. The results of antenna efficiencies and channel capacities for different handheld situations are presented and discussed.
