碩士 === 南臺科技大學 === 電子工程系 === 106 === This thesis proposes two designs of antennas for smart watch devices. First one is a WLAN MIMO antennas for smart watch applications; second one is a design with antenna on smart watch for LTE/DCS/PCS/UMTS application. First one is the design of WLAN MIMO antennas for smart watch applications. The overall dimensions of the MIMO antenna design are 41 × 41 × 4.8 mm3, with a ground plane size of 35 × 35 mm2. In this case, a dual-band MIMO antennas for smart watch operating at WLAN 2.4/5.2/5.8 GHz bands is proposed. The antenna design uses loop structure to achieve the design goal. In order to achieve desirable dual-band WLAN operation, an inductor chip is connected in series between the loop arm and the system ground. Second one is the design with antenna on smart watch for LTE/DCS/PCS/UMTS application. The overall dimensions of the MIMO antenna design are 40 × 40 × 12.8 mm3, with a ground plane size of 40 × 40 mm2. The design can contain the application bands of LTE/DCS/PCS/UMTS. The antenna use the PIFA structure. The longest path extends from the planar architecture to the frame, and then the copper strip is added to the upper edge of the frame to match the application frequency bands.
