在本論文中,我們設計了操作在5GHz無線區域網路的印刷式偶極天線,並加上雙面直角反射器。阻抗的匹配是採用四分之ㄧ波長轉換器。為了驗證模擬結果,採用Duroid RO4003的板材實作,量測5GHz~6GHz的增益和反射損耗,都能夠達到所需要的。此外,天線的HPBW也滿足了設計目標。
In this thesis, printed dipole arrays with corner reflector fed by microstrip and twin line are designed at 5GHz for WLAN system application. The quarter-wavelength transformer is used for impedance matching. For verification, prototypes are implemented and measured at 5~6GHz with Duroid RO4003 PCB. Results show that good gain spectrum and impedance matching are obtained. In addition, the HPBW of the radiation pattern meets the design goal.
