| dc.description.abstract | 在本論文將利用平面式倒F天線(Planar Inverted-F Antenna, PIFA)形式的天線，設計出一個涵蓋GSM900/DCS1800/PCS1900/UMTS2100手機頻帶的天線。剛開始針對天線的設計參數，做一系列的探討與分析，如天線的裂孔、形狀、裂孔、彎曲線做一系列分析，並提出一新的概念T型孔槽來調整高頻，於章節最後整理出一天線設計參數總表。
並根據整理出來的參數，照天線的設計流程，再加上寄生天線的應用，設計出雙頻和四頻天線，在最後並利用實作與模擬之間的比較來探討天線的效率、增益、幅射場型等特性，並試著探討實作與模擬之間差異，使得設計的天線可以真正的在商場上應用。 | zh_TW |
| dc.description.abstract | This paper is to design a quad-band (GSM900/ DCS1800/ PCS1900/ UMTS
2100 bands) handset antenna by using Planar Inverted-F Antenna (PIFA) type structure for wireless markets. In the beginning, parameters for designing antenna are focalized and a series of topics are analyzed and researched like antenna slot, pattern, slit, meander line...etc. For adjusting high frequency part, a new concept of T slot is proposed. A table of organized antenna-design-parameters is in the last chapter.
Dual band and quad band antenna are designed based on the table of organized antenna-design-parameters, antenna-design-methodology and application of parasitic-antenna. For studying antenna characteristic of efficiency, gain, radiation pattern...etc. and also trying to understand the differences between computer simulations and hands-on experiments, comparisons between computer simulations and hands-on experiments are done. Finally, this really makes the designed-antenna
commercialized. | en_US |
