本論文主要是因應現今應用於手機裝置的內藏式多頻天線需求，探討各式微小型天線設計的可行性，選用環形天線做為設計型態，提出四款天線設計，分別為：“適用於小接地面之摺疊環形手機天線設計”、“微小型摺疊環形手機天線設計”、“具有晶片元件匹配電路之印刷式環形手機天線設計”以及“具有印刷式匹配電路之印刷式環形手機天線”；前二項設計分別為體積1.0 cm3以及0.6 cm3之立體結構，大約是目前的多頻內藏式天線體積的一半，而後二項設計則是平面印刷式結構，且僅佔用少於一半的天線區間；四項天線設計皆可達成WWAN頻帶之四頻或是五頻操作。

In this dissertation, the study mainly focuses on small-size multiband mobile phone antennas for practical applications. Loop antenna is chosen to be the antenna type for designing the compact internal multiband antenna. Four antenna designs are presented, including “Compact Multiband Folded Loop Chip Antenna for Small-Size Mobile Phone”, “Very-Small-Size Folded Loop Antenna with a Band-Stop Matching Circuit for Penta-Band Mobile Phone Application”, “Very-Small-Size Printed Loop Antenna for GSMDCSPCSUMTS Operation”, and “Printed Loop Mobile Phone Antenna with an Internal Printed Matching Circuit”. The first two antenna designs occupy a volume of 1.0 cm3 and 0.6 cm3 respectively and the last two antenna designs are to be directly printed on the system circuit board of the mobile phone. Either of them can operate as a quad-band antenna for GSM/DCS/PCS/UMTS operation or as a penta-band antenna for GSM850/900/1800/1900/UMTS operation.
