本論文使用時域有限差分法成功的去研究U型槽平板天線及改良式U型槽平板天線的特性,而不是用商業軟體如HFSS、IE3D以及CST去作研究。時域有限差分法的準確性由實驗量測證明正確無誤。利用壹矩形金屬細長片與底層中心線成各種不同角度取代底層金屬板去改良U型槽平板天線,結果發現此改良式U型槽平板天線可以產生多頻區運作、寬頻帶、好的輸入阻抗匹配和高的天線效率。如果U型槽平板天線金屬底層嵌入U型磁性材料小平板,結果發現在逆程損耗10 dB 以上的頻寬變得非常寬且天線效率提高了。
The finite-difference time domain(FDTD) method, instead of commercial software packages such as HFSS, IE3D, and CST, is successfully used to study characteristics of U-Slot and modified U-slot Patch Antennas. The validation of the FDTD method is checked by measurements. The modified U-slot patch antenna using a metallic oblong-patch with different angles is respected to the center line as the bottom layer has been proven that it can provide wide-band enhancement, multi-band operation, good impedance matching, and high antenna efficiency. Finally, The modified U-slot patch antenna with a small ferromagnetic U-strip inserted in the metallic bottom layer has been shown to provide a return loss in excess of 10 dB over an extremely wide frequency range and high antenna efficiency.
