本論文提出兩款設計分別應用於智慧型行動裝置與智慧型手錶，針對第五代行動通訊所做的設計，包含 LTE、WI-FI 6E、Sub 6 GHz 這些頻段，智慧型手機以槽孔天線為主要設計；智慧型手錶天線主體以耦合電容饋入式 IFA 天線設計。
　　智慧型手機天線設計利用槽孔末端饋入所產生的虛短路，產生多模態，減少了天線的數量，其中覆蓋了 LTE 低頻、中高頻、WLAN 2.4 GHz、WLAN 5 GHz 以及 Sub 6 GHz 等頻段；利用輻射方向不同的方式，縮小天線之間的距離，將 WLAN 2.4 GHz 、WLAN 5 GHz 以及 FR 1 n77、n79 皆以 4 × 4 MIMO 天線的方式來增加傳輸效率。
　　智慧型手錶天線主體以耦合電容饋入式 IFA 天線設計在基板厚度為 0.2 mm 的 FR4 基板上，使整體機構重量減輕，利用 IFA 天線多路徑特性，涵蓋了 FR 1 n77 ~ n79 與WI-FI 6E 全頻段，在有限的空間中，皆符合 2 × 2 MIMO 的標準

　　This paper proposes two designs to be applied to smart mobile devices and smart watches respectively. The design for the fifth generation wireless systems, including LTE, WI-FI 6E, Sub 6 GHz frequency bands, the smart phone is mainly designed with slot antenna. The main body of the smart watch antenna is designed with a coupling capacitor fed IFA antenna.
　　The smart phone antenna design uses the virtual short circuit generated by the non-terminal feeding of the slot to generate multi-modality and reduce the number of antennas. Frequency bands covers LTE low frequency, mid-high frequency, WLAN 2.4 GHz, WLAN 5 GHz and Sub 6 GHz. Using different radiation directions to reduce the distance between antennas, WLAN 2.4 GHz, WLAN 5 GHz and FR 1 n77, n79 are all used as 4 × 4 MIMO antennas to increase transmission efficiency.
　　The main body of the smart watch antenna is designed on the FR4 substrate with a substrate thickness of 0.2 mm with a coupling capacitor fed IFA antenna, which reduces the weight of the overall mechanism. Using the IFA antenna multi-path feature, covering FR 1 n77 ~ n79 and WI-FI 6E frequency bands, in a limited space, all meet the 2 × 2 MIMO standard
