本篇論文主要於全金屬機殼變形筆電（筆電與平板2合1）Hinge上，設計2.4GHz /5 GHz /2.4 GHz &5 GHz小型化天線；第一章說明研究背景與目的，並簡單陳述各章節之內容；第二章裡主要設計2G頻段，並利用偶極天線，在筆電模式時可激發兩hinge間的槽孔，提升天線整體效能，在轉為PAD模式時，由於金屬件遮擋面積較小，天線淨空區變大，進提升此模式天線效能。第三章主要設計5G頻段，並利用PIFA天線架構，設計架構上較為簡化，而且也達到相同效果。第四章，由於市場上的筆記型電腦普遍為雙頻收訊，單頻收訊已不敷消費大眾使用，因此利用單極天線加寄生元件的架構，設計雙頻天線，第五章，說明本篇所提出與Hinge整合的2.4GHz /5 GHz /2.4 GHz &5 GHz小型化天線能夠確實運用在全金屬變形筆電機殼中，以同時達到滿足外觀質感與提升接收訊號品質的要求。

The Thesis focuses on the design of 2.4 GHz / 5 GHz / 2.4 GHz & 5 GHz Compact Antenna in the all-metal chassis transformer notebook hinge ( Notebook and tablet 2 – in - 1 ). In the first chapter describes the research background and purpose, and states the contents of each chapter briefly. In the second chapter, the design of 2.4 GHz frequency band and the usage of dipole antenna are described. In the notebook mode, it can stimulate the slot between two hinges and enhance the performance of the antenna. The antenna is improved as well when it is converted to pad mode. The antenna clearance area becomes larger due to the smaller metal shielding area in pad mode. In the third chapter, we design 5 GHz frequency band and use ( PIFA ) antenna. The design of ( PIFA ) structure is simplified and make performance as good as well. In the fourth chapter, the monopole antenna and parasitic element architecture are used to design dual - band antennas since the single-band receivers are gradually eliminated in the market. In the fifth chapter,
the design of 2.4 GHz / 5 GHz / 2.4 GHz & 5 GHz Compact Antenna integrated with the hinge is described in this article. This design can be used in an all - metal transformer book chassis as well and to satisfy both the appearance texture and the quality of the received signal.
