本論文的研究主要為應用在全金屬機殼筆記型電腦之LTE接地面輻射天線,三款天線皆利用接地面天線的方式設計,第一款天線使用一個開槽孔的饋入機制激發金屬接地面輻射,並加入RLC元件調整阻抗匹配,應用頻段為LTE 700~960 MHz,此天線不與系統地做連接,可放置於螢幕上方和螢幕與鍵盤樞紐處;第二款天線為在金屬背蓋上置入一個開槽孔饋入機制,利用開槽孔周圍的迴圈電流耦合至接地面上產生電流而輻射,應用頻段為LTE 700~960 MHz,經過實際量測,頻率可達40%以上,並加入多天線的MIMO技術做探討;最後一款天線為利用一個單極天線產生高頻頻段,並耦合至金屬背蓋上方之開槽孔,利用開槽孔周圍與接地面上之電流產生低頻頻段,頻段涵蓋LTE 700~960 MHz、2300~2700 MHz,經過實測,整體效率皆在35 %以上。
This thesis provides an in-depth design of LTE ground radiation antenna mounted on metal casing of laptop computer. The three proposed antennas are designed based on the ground radiation antenna;The first antenna uses an open slot fed mechanism to excite the current from the metal ground, with a bandwidth of 40 % at LTE 700~960 MHz. This antenna will not be connecting to the system ground, and it can be used on the top of the panel and hinge. The second antenna is an open slot fed mechanism on the metal back cover.The surrounding current of the slot couples to the current on the cover to emit radiation.The experimental evaluation we applied have illustrated that the frequency operates at LTE 700~960 MHz with efficiency reaching 40 %. Finally, we add the technology of MIMO. The last antenna uses a monopole to produce a high frequency, and couples to an open slot on the metal back cover.The open slot and the current of the metal back cover provide a low frequency at LTE 700~960 MHz and LTE 2300~2700 MHz. The efficiency has reached over 35 % after the experimental evaluation.
