本論文提出應用於第五代通訊低特定電磁波能量吸收率智慧型眼鏡天線之設計，隨著元宇宙與第五世代行動通訊的發展，智慧型眼鏡成為全球各科技大廠積極布局的領域，提出兩款天線設計分別應用於VR及AR的智慧型眼鏡，眼鏡架構採用3D列印技術製造，與天線達到緊密結合。
第一款天線為具4X4 MIMO之第五代VR眼鏡天線設計，應用頻段為5G FR1 n77/78/79頻段。運用單極饋入耦合至金屬牆激發雙模態，透過模態分集機制設計4× 4 MIMO天線，最後運用天線相關係數計算MIMO多樣性指標係數(ECC、DG、TARC、MEG、CCL)，符合低耦合特性。
第二款天線為應用於第五代通訊多模共振AR 眼鏡天線裝置，頻段涵蓋Wi-Fi 6E、5G FR1 n77/78/79 及mmWave n261，在Sub - 7GHz頻段下設計一款立體式結構具備Monopole、Slot及Loop三種共振模態耦合機制天線達到寬頻設計，運用多種縮小化設計，整體面積尺寸減少了50 %，在mmWave頻段使用1 × 4串列式 Dipole陣列天線，搭配T型功率分波器達到高增益，並加裝反射板於天線背面，增強天線指向性進而提升增益。
最後，分析加入人體頭顱模型對眼鏡天線的影響，使用HFSS模擬SAR值分佈圖，並針對不同的眼鏡材料進行探討，驗證所設計的VR/AR眼鏡天線符合實際應用環境且具有良好的性能。

In this thesis, the low SAR smart glasses antenna designed for fifth-generation communication. With the concept of Metaverse and the development of fifth-generation mobile communication, smart glasses have become an active area for global technology companies. Two antenna design solutions are proposed for VR and AR smart glasses. The skeleton of the glasses is manufactured by 3D printing technology and is closely integrated with the antenna.
The first antenna is a fifth generation VR glasses antenna with 4X4 MIMO in the 5G FR1 n77/78/79 bands.Dual mode excitation using a monopole feed coupled to a metal wall.Design of 4×4 MIMO antenna by modal diversity mechanism.Finally, the performance parameters (ECC, DG, TARC, MEG, CCL) of the MIMO antenna are calculated.The low coupling characteristics are satisfied.
The second antenna is a multimode resonant AR glasses antenna device ..The frequency bands cover Wi-Fi 6E, 5G FR1 n77/78/79 and mmWave n261. A three-dimensional structure with monopole, slot and loop mode coupling mechanisms was designed in the sub-7GHz band, enabling multiple miniaturized broadband designs and reducing the overall area size by 50%. A tandem dipole array antenna was used in the millimeter wave band. Use a power divider with a T-junction and add a reflector plate at the back of the antenna to improve the antenna gain.
Finally, the effect of adding the human skull model on the glasses antenna was analyzed, and the distribution of SAR values was simulated by HFSS.Comparison of different glasses skeleton materials.It is verified that the designed VR/AR glasses antenna is suitable for practical applications and has good performance.
