本論文採用了一個新型的雙三角形單極天線,最主要是利用兩個三角型的結構,來激發出兩個頻率,且符合無線區域網路所要求的規格(2400~2484MHz與5150~5350MHz)。此兩個三角形最大的特點就是能夠造成電流路徑的增加,使彼此相鄰的共振頻率延伸成為一完整的頻帶,造成頻寬增加的效果,並且因為結構簡單,相對的設計的彈性也較大較方便。在研究中,我們將經由高頻模擬軟體來個別討論所設定的各個參數,並分析其對天線所帶來的影響,並尋求其最適合的特性。
本天線除了應用在基本的FR4基板上,也會利用氧化鋁與LTCC材料(Dupont 951 tape)來進行模擬與實做,希望利用此一結構,能夠提供具有較高介電常數材料的LTCC設計的空間,使因介電常數上升所造成的頻寬下降得到改善的方式。
A novel double triangular monopole antenna is proposed. The double triangular structure can not only excite two different resonance frequencies but have better bandwidth to meet the WLAN required specifications (2400~2484MHz and 5150~5350MHz). These two triangles are mainly used to increase the electric current path. The resonant frequencies can be combined to form a wide bandwidth due to the multiple current paths. The proposed antenna has simple structure and can be designed and realized easily. By using the high-frequency simulation software (HFSS), we can obtain the best parameters for the realization of the antenna.
The antennas are made on typical FR4 substrate and alumina and the simulation for LTCC material will also be provided. The new antenna can improve the problem of narrow band width which often accompanies with the materials of higher dielectric constant.
