摘要(中)	在當今行動通訊裝置日漸普及的時代，無線傳輸技術的發展也跟著突飛猛進。我們不斷地把行動裝置迷你化，並且盡可能加入更多的功能來滿足現在人類生活日常所需，然而為了配合行動通訊裝置的諸多功能，無線傳輸的技術也日新月異，不斷進步起變得更為複雜。從過去的單支、單頻、外露式天線，變單支、多頻、隱藏式天線。本篇論文討論智慧型手機內的PIFA接地點與feed之間的關係會導致低頻在輻射效率上的變化，以及在單支單頻PIFA如何增加其他頻段並且盡量讓不同頻段不互相干擾，並且通過改變智慧型手機原有天線的設計方式來重新加入LTE band 7，也同時能夠符合該智慧型手機天線客戶的輻射標準。結論討論到在現今的智慧型手機設計上出現的問題，包含所需天線數量遽增，單支天線涵蓋頻段數量也越來越多，手機的功能越來越多時同時也增加了許多硬體零件，像是NFC、數顆鏡頭、碩大的螢幕與電池與相當薄的機身等都是使智慧型手機天線設計難度越來越高的原因，在本論文也會分析這些零組件中影響天線效率最多的零組件。
摘要(英)	Nowadays, communication mobile devices are becoming more popular, and the technology of wireless communication is also getting progressive. People keep minimizing the mobile devices, and adding multiple functions to fulfill the daily needs of people. However, for coordinating with the multiple functions on mobile devices, technology of wireless communication has become more complicated. In the past, there was only one-single band on one-exposed antenna. But now there are multiple bands on one embedded antenna.. In this thesis, we are researching on how the relation between the feed and shorting pin influences the low frequency band and how to add different bands into single-band PIFA and not to impact other bands. At the same time, we also re-design and add LTE band 7 into the PIFA to fulfill the spec. of client. Conclusion is about the common problems of antenna design on smartphone. Including the rising number of antennas and covering multiple bands on each antenna. With the rising number of antennas, there are also more electronic parts like NFC, cameras, giant screen and battery and thin body making antenna design more difficult. It is also discussed that which electronic part impacts the efficiency most.
