本論文提出一具有帶拒功能的超寬頻平面天線。在橢圓形天線上挖一C形槽孔來達到帶拒頻寬,槽孔的長度控制帶拒的中心頻率與頻寬,此天線具有帶拒功能並且可以應用在超寬頻通訊系統上,在VSWR小於2的頻段為3-12 GHz。
另一個提出的超寬頻天線為叉形的結構,其頻段為3.5-11 GHz。首先此矩形天線製作於FR4基板上並利用50歐姆微帶線來激發,藉由最佳化接地面的寬度、微帶線的寬度與位置,來達到UWB的頻段。接著再對矩形挖槽並調整矩形槽孔的長寬,使整個叉形結構一樣擁有UWB的頻寬。這些提出的天線其輻射場型具有單極天線特性,且模擬值和量測值有相當的一致性。
The purpose of this thesis is present a planar ultra-wideband antenna with a band-notched characteristic. By inserting a C-shaped slot on the elliptic radiating patch, a notched frequency band is created. The slot length contributes to both the notch center frequency and notch bandwidth. This antenna design is a breakthrough for selecting the notch band and can be directly applied to UWB communications where the band-notched characteristic is needed. In this design, a 3-12 GHz frequency range for VSWR less than 2 is obtained.
Another UWB antenna is a tuning fork type structure. It exhibits a 10 db return loss bandwidth over the entire frequency band from 3.5GHz to 11 GHz. The structure is designed by first considering a rectangular patch antenna on FR4 substrate fed with a 50 ohms microstrip line. The width of the partial ground, the width and position of the feedline are optimized to satisfy the operation requirement of UWB. The rectangular patch is then finally modified to tuning fork structure by maintaining the UWB frequency range.
Our proposed antennas show monopole-like radiation pattern and good agreement has been obtained between the simulation and experiment results.
