本論文呈現小型化雙頻帶共平面波導天線結合電磁能隙架構。共平面波導天線與電磁能隙架構製作於FR4基板上。操作中心頻率為2.45 GHz 和5.7 GHz 無線區域網路頻帶。其中天線設計與電磁能隙架構設計,以及天線結合電磁能隙架構結果將呈現。天線尺寸為30×24.8mm2,共平面波導天線饋入線的特性阻抗為50Ω,而電磁能隙架構是由3×3元件陣列構成,電磁能隙尺寸為63×63 mm2。將共平面波導天線與電磁能隙架構結合後,在高頻5.7GHz部分,能有效減少前向後輻射7.5dB和提升天線增益值2.9dB,而在低頻2.45GHz部分,能有效前少前向後輻射11dB和提升天線增益值1.28dB。本論文應用HFSS模擬軟體驗證,並進行模擬與量測比較。

This thesis presents a compact dual-band coplanar waveguide (CPW) antenna in combination with a compact electromagnetic band-gap (EBG). The CPW antenna and EBG structure are fabricated on FR4 substrates. The center operating frequency are 2.45GHz and 5.7GHz, which can be applied for wireless local area networks bands. Design of the antenna、EBG structure, and the antenna with EBG structure are presented in this work. The antenna size is 30×24.8mm2 and the characteristic impedance of CPW feed line is 50Ω. The EBG structure is an array of 3×3 cell constitute and the size is 63×63 mm2. When CPW antenna integrated with EBG structure, front to back radiation reduces 7.5dB and improves antenna gain 2.9dB for high frequency band;and front to back radiation reduces 11dB and improves antenna gain 1.28dB for low frequency band simulator, and the simulated results are compared with measured ones. The HFSS simulation software is used of this thesis, and the result compare with simulated and measured one.
