本論文提出適用於平板裝置之組合式天線設計，並且皆可涵蓋三寬頻(698~960 MHz、1710~2690 MHz及3400~3800 MHz) LTE/WWAN頻帶。其中第一項天線設計，具有可操作於中頻頻帶的主結構，利用低頻支路電感耦接至主結構來組合出低頻頻寬，接著再簡單與一短支路組合增加高頻頻寬，天線整體為全平面印刷且可在尺寸僅10 ∗ 45 mm2大小下達成三寬頻LTE/WWAN操作；第二項天線設計，其主結構具有一超寬頻頻寬可涵蓋中頻及高頻頻帶，於低頻則利用第一項天線設計的技術來產生模態，並將天線與一內建高通匹配電路組合進而增加低頻頻寬，此時大幅縮小天線所佔淨空區至10 ∗ 35 mm2；第三項天線設計，接著使用一個簡單的單極天線結構與一內建低通匹配電路組合，來涵蓋中頻寬頻頻帶，接著以先前所提之技術來涵蓋低頻寬頻頻帶，最後於高頻頻寬則與一短支路組合來達成，而天線所佔淨空區更縮小至10 ∗ 30 mm2，並且具有良好的天線輻射特性。

In this thesis, novel combined-type antennas having three wide operating bands (698~960 MHz, 1710~2690 MHz, and 3400~3800 MHz) to cover the LTE/WWAN operation for tablet devices are presented. In the first design, the antenna uses a main structure thereof to provide a wide middle wideband of 1710~2690 MHz. Then, by combining an inductively coupled low-band branch strip with the main structure, the antenna can cover the desired lower wideband of 698~960 MHz. By further simply adding a short branch strip, the desired higher wideband of 3400~3800 MHz can be obtained. The antenna can achieve triple-wideband LTE/WWAN operation and occupy a small size of 10 ∗ 45 mm2 with a uniplanar structure. The second antenna design uses a main structure to provide an ultra-wideband of 1710~3800 MHz to cover the desired middle wideband and higher bandwidth. Then the desired lower wideband is achieved by applying the technique used in the first antenna with a high-pass matching circuit. The occupied clearance region of the second antenna is greatly decreased to 10 ∗ 35 mm2 only. The third antenna design uses a simple monopole structure integrating an internal low-pass matching circuit to cover the desired middle wideband and decrease the clearance region needed. In addition, by applying the previously presented techniques, the desired lower wideband can be generated. For the desired higher wideband, it is achieved by simply adding a short branch strip. Furthermore, the third antenna can be disposed in a smaller clearance region of 10 ∗ 30 mm2 with good radiation characteristics.
