摘要

本論文為了讓微帶天線能夠有效的應用於射頻辨識系統(Radio Frequency Identification,RFID)、無線區域網路(Wi-Fi)及行動電話等等無線通訊設備之上，針對雙頻(2.4GHz、5.2GHz)的槽孔微帶天線(Microstrip-Fed Slot Antenna)進行研究。
槽孔微帶天線的組成包括介電基板，頂部為一矩型微帶線，和在接地面上刻出所設計之槽孔。本論文探討的天線結構包括L型槽孔微帶天線、雙L型槽孔微帶天線及雙L型圓型槽孔微帶天線。應用HFSS軟體進行模擬的過程中改變天線結構的多項參數，討論其對天線特性之影響，接著以模擬得到之結果數據，將雙L型圓型槽孔微帶天線，使用FR4基材進行實作與量測，將實作結果與模擬之結果做比較。
最後針對以1.5倍波長計算槽孔長度，設計天線結構，並且進行相關性研究，希望可以利用其特性更進一步改善天線效能；將其結構套用於L型槽孔微帶天線、雙L型槽孔微帶天線及雙L型圓型槽孔微帶天線，依序模擬比較；並且探討其與原本的天線結構之差異性與優缺點。

This thesis in order to allow the microstrip antenna can be used in the radio frequency identification system, wireless LAN and phones, and so on. This study is for the dual-band (2.4GHz, 5.2GHz) slot microstrip antenna.
Slot microstrip antenna composed mainly of a dielectric substrate, microstrip lines and the ground plane carved out of the slot. The antenna structure discussed in this paper have L-shaped slot antenna, double L-shaped slot microstrip antenna and two L-shaped circular microstrip antenna slot. Used HFSS software simulated and changing the parameters of the antenna structure in the process, and to discuss its implications.
The simulation results through FR4 to make double L-shaped circular slot antenna, and measurement, and then compare the results of the simulation and measurement.
Finally, the design of the antenna structure to 1.5 times the wavelength calculation slot length. We are hoping to improve antenna performance. We use this structure in L-shaped slot antenna, double L-shaped slot microstrip antenna and two L-shaped circular microstrip antenna slot. We are explore the differences between this structure and the original antenna structure.
