 本論文提出應用於第五代行動通訊的VR眼鏡天線與抑制旁波瓣的毫米波陣列天線，隨著科技的進步與行動通訊的發展，智慧眼鏡與毫米波的需求也逐漸增加，提出了一款應用於VR眼鏡的天線設計，並且探討如何抑制毫米波陣列天線的旁波瓣，眼鏡本體採3D列印製作而成。
第一款天線為具有毫米波VR眼鏡天線設計，涵蓋頻段Wi-Fi 6E、5G - FR1 n77/n78/n79頻段及5G FR2 n261頻段，在Sub – 6GHz以下頻段使用單及天線饋入耦合至金屬牆形成雙模態，在mmWave頻段使用1 x 4 Vivadi陣列天線，並結合T型功率分配器，最後加入SAR值模擬使VR眼鏡天線更貼近生活運用。
第2款天線以兩種不同型式設計仿生天線，以三階費氏陣列天線為例，探討此種天線擺放方式對於旁波瓣的抑制效果，再發展至四階、五階費氏陣列天線，驗證越多階層旁波瓣抑制的效果是否越好，最後以四種數量相同但不同排列方式，比較其差異性。

關鍵詞：VR眼鏡天線、毫米波陣列天線、韋瓦第陣列天線、MIMO天線設計、仿生技術、旁波瓣抑制 

This paper proposes antenna designs for VR glasses applied in fifth-generation mobile communications, along with millimeter-wave array antennas for side lobe suppression. With the advancement of technology and the development of mobile communications, the demand for smart glasses and millimeter-wave applications has increased. A antenna design for VR glasses is presented, and the suppression of side lobes in millimeter-wave array antennas is explored. The glasses body is manufactured using 3D printing technology.
The first antenna design covers the frequency bands of Wi-Fi 6E, 5G - FR1 (n77/n78/n79), and 5G FR2 261. It utilizes a single-feed coupling to a metallic wall to form a dual-mode configuration below the sub-6GHz frequency range. In the mmWave frequency range, a 1x4 Vivaldi array antenna is used, combined with a T-shaped power splitter. SAR simulations are also incorporated to enhance the applicability of the VR glasses antenna in daily life.
The second antenna design focuses on the biomimetic antennas using different configurations. Taking the third-order Fibonacci array antenna as an example, the effect of antenna placement on side lobe suppression is investigated. The study further expands to fourth-order and fifth-order Fibonacci array antennas to verify if higher-order configurations yield better side lobe suppression. Additionally, four different arrangements with equal antenna quantities are compared to examine their differences.

Keywords: VR glasses antenna, millimeter-wave array antenna, Vivaldi array antenna, MIMO antenna design, biomimetic technology, side lobe suppression.
