本論文提出適用於無線通訊與穿戴裝置之天線設計，分別為兩款Dongle天線與一款手錶天線設計 :
第一款為適用於WLAN頻帶的 Dongle印刷式多臂天線：整體架構之尺寸為40 mm × 10 mm × 1.6 mm，天線主體面積為10 mm × 10 mm。本天線應用頻段乃使用一個單極天線與分支路徑調整阻抗匹配而得。
第二款Dongle天線屬於無線收發之多頻應用：可應用頻段包含WLAN (2.45 GHz、5.2 GHz、5.8 GHz)、WiMAX (2.5 GHz、5.25 GHz)、以及LTE (2300 MHz、2500 MHz)整體架構之尺寸為55 mm × 13 mm × 1.6 mm。本天線在低頻2~3 GHz產生兩個模態: 此乃由地面與槽孔兩諧振阻抗匹配而成，在3 GHz有一個模態為地面開槽孔共振而成，其高頻為增加右側金屬片調整地面的高階模態所產生。
第三款為目前科技業爭相研發適用於智慧錶之Wi-Fi MIMO天線設計：天線整體尺寸為40 mm × 40.2 mm × 5 mm，本款天線設計採用立體架構之直立式IFA天線，材質以銅片做為設計，正反兩面使用，共同地面方式設計，以及模擬手錶機殼與螢幕等特性，經由模擬所需之結構皆可調整天線主路徑至所應用頻帶，故適用於無線穿戴裝置上。

In the thesis, we proposed two compact printed Dongle antennas and a printed antenna on smart connected device for wireless communication and wearable device.
The first paragraph, a printed multi-arm antenna for WLAN dongle application is proposed. The overall size of antenna is 40 mm × 10 mm × 1.6 mm and area of the antenna is 10 mm × 10 mm. The impedance matching can be achieved by using a extended monopole and the path of branch on the antenna design.
In second paragraph, the multi-frequency dongle antenna applies for the wireless transceiver is presented; the overall size of antenna is 55 mm × 13 mm × 1.6 mm applied frequency band to include WLAN (2.45GHz, 5.2 GHz, 5.8 GHz), WiMAX (2.5 GHz, 5.25 GHz) and LTE (2300 MHz, 2500 MHz). The antenna has two modes in low-frequency at 2 to 3 GHz: Two resonances impedance matching are produced from the ground and the slot. One resonance mode is made from the ground open slot at 3 GHz. Finally, we added the metal patch at right side to adjust the mode of 3 GHz to generate high frequency band.
In third paragraph, a MIMO antenna design on smart watch for Wi-Fi band is proposed. The overall size of the design is 40 mm × 40.2 mm × 5mm. The antenna design uses three-dimensional vertical cooper IFA antenna architecture design. Front and Back grounds in the design use a common ground and simulates smart watch’s shell and screen of the characteristic. From the results, we can adjust important parameters of proposed antenna to achieve the desired bands. This design can be applied in wireless communication and wearable devices.
