本論文針對行動手機提出一項六頻天線設計,由兩個天線以雙饋入的方式分別包含DTV/GSM850/900及DCS/PCS/UMTS之操作頻帶。在DTV/GSM850/900之操作上,我們提出一種創新的設計,即是使用偶極天線的設計概念,再加上一匹配機制,能成功激發出偶極天線之半波及全波模態,同時適當控制該匹配機制,能有效控制兩模態之頻率比,因此可將模態結合成一寬頻操作。而在DCS/PCS/UMTS之操作上,則是使用一槽孔天線,其長度決定最低操作頻率,且適當調整其匹配,即可獲得所需求的操作頻寬。我們也討論機殼及人體效應對天線的影響,可以發現於DTV/GSM頻帶之輻射效率會高於DCS/PCS/UMTS頻帶,但不論輻射特性如何,天線會因人體為高介質及高損耗之因素,在效能上會大受影響。
A six-band antenna design for the mobile phone is presented. The required bandwidth for DTV/GSM850/900/DCS/PCS/UMTS operation is achieved by using two antennas. For DTV/GSM850/900 operation, we propose a novel antenna by using the concept of the dipole antenna and an internal matching portion to excite the half- and one-wavelength resonant modes of the antenna. With the internal matching portion, the frequency ratio of the two resonant modes can be controlled, thereby making the two resonant modes formed into a very wide operating band. For DCS/PCS/UMTS operation, a novel monopole slot antenna is used. The lower-edge frequency of the slot antenna depends on its length and the required bandwidth can be achieved by adjusting its tuning section. Effects of casing and human body on the proposed mobile phone antenna are also discussed. It is found that the radiation efficiency of DTV/GSM bands is larger than that of DCS/PCS/UMTS bands in this design. However, overall the operating bands, the antenna performances are greatly affected when the human effects are taken into considerations.
