本論文主要利用印刷式電路板設計應用於超寬頻系統(UWB)之天線設計,涵蓋頻段為3.1-10.6 GHz。首先在本論文中,先介紹超寬頻系統之發展與技術應用,接下來介紹本論文所研究與製作應用於UWB系統之橢圓偶極天線,主要發表兩種不同材質所製作的橢圓偶極天線,首先利用FR4板材介電係數4.2製作橢圓偶極天線,接著利用高介電係數10.2板材,依照相同的設計方式縮小天線的體積,研究與製作橢圓偶極天線之量測反射損耗(s11)、史密斯阻抗圖(smith chart)及場型圖(radiation patterns),將會在本論文中詳細呈現。
Printed-circuit board (PCB) antenna with useful bandwidth covering from 3.1 GHz to 10.6 GHz is suitable for wireless ultra wideband (UWB) application. Firstly, we present UWB developed and application. Next, to present a low profile, elliptical antenna etched on PCB with dielectric constant 4.2 achieving the above specified bandwidth. And then, to reduce the size of the product, an elliptical dipole antenna with PCB dielectric constant 10.2 has been fabricated. Swept frequency return loss, impedance and radiation patterns of these antennas have been measured. Design criteria for this elliptical dipole antenna is also investigated.
