摘要(中)	本論文提出的設計是採用小型化表面黏著貼片印刷式電路板設計之5G FR1 多頻段天線，天線本體尺寸為10×46.5×3.2??^3 於區域物理大小15×50 ??^2中，搭接在系統的主板尺寸135×50??^2上，此設計技術可以廣泛應用於車載通訊、物聯網及行動通訊裝置。 表面黏著貼片印刷式電路板天線之設計理念是由二組單極天線為基礎加以改良，並利用電容耦合的共振機制搭配匹配電路所呈現的設計架構。首先，在天線本體尺寸空間調整第一單極天線的幾何結構，接著利用本體空間之另一部分調整第二單極天線結構，且在天線共振路徑上加蜿蜒線路(Meander Line)來產生低頻所需之電感值減少天線體積，經第一單極天線訊號饋入與第二單極天線結構接地產生電容耦合共振機制，再利用匹配電路達到八個共振模態，其中低頻0.617GHz至0.960GHz為雙重共振；中頻1.71GHz至 2.17GHz、2.30GHz至2.40GHz及2.50GHz至2.70GHz為四個共振模態；高頻3.30GHz至3.80GHz為雙重共振。八個共振頻率點中，低頻|?11|頻寬涵蓋中反射係數為為-6dB，中、高頻|?11|頻寬涵蓋中反射係數為-10dB。詳細的天線設計及實驗數據，將在本論文中逐一介紹。
摘要(英)	A miniature antenna design using Surface-Mount devices for the fifth-generation FR1 broadband is proposed in this thesis. The proposed antenna, which is of 10×46.5×3.2??^3 in volume, is deployed in an antenna clearance area of 15×50??^2 in a printed circuit board of 135×50??^2. This technology can be widely applied for not only Vehicle-to-Everything Communication (V2X), but also Internet-of-Things (IoT) networks and mobile communication systems. Antenna design concept of miniature Surface-Mount-Device technology is based on the basic theory of monopole antenna, and it demonstrates that the structure of antenna is designed using capacitive coupled resonant mechanism with antenna matching circuit network. To begin with, the geometry monopole antenna structure on dimension 10×46.5×3.2 ??^3 volume is first adjusted. Then, the second geometry monopole antenna pattern on the rest of the volume is attached. At the same time, a meander line along the second monopole antenna path is used to increase natural inductance of low band for reducing antenna size. Both two monopole antennas are integrated together with feeding the first monopole antenna and shunt grounding the second monopole antenna under capacitive coupled resonant mechanism to produce eight antenna resonances while implementing antenna matching circuit network. The bandwidth of low band is operated from 0.617GHz to 0.960GHz due to the double resonant modes. The bandwidth of middle band is operated from 1.71GHz to 2.17GHz, 2.30GHz to 2.40GHz, and 2.50GHz to 2.70GHz due to multiple resonant modes. The bandwidth of high band is operated from 3.30GHz to 3.80GHz also due to double resonant modes. Detailed antenna design and experimental results are also introduced and discussed.
