dc.description.abstract | 在本研究課題中,我們設計了新型寬頻帶單極化雙貼片“L”型探針饋電的天線單元。並將天線單元排列成兩個和六個的天線,它們的效能(仿真計算和原型測量)己加以比較和分析。本天線是設計用於個人通訊系統(PCS),碼分多址(CDMA)和國際移動通訊系統2000(IMT-2000)。工作頻率從1.71GHz至2.17GHz,帶寬達到25%。在此頻率範圍內,天線和天線陣的駐波比小於1.5,水準輻射主瓣寬度為約60度、後瓣強度為小於-24分貝和交義極化強度為小於-15分貝。兩單元天線陣的增益達11.5dBi,而六單元天線陣的增益達15dBi。同時,六單元天線陣是帶成形波束輻射的,以加強發射和接收的效率。 | |
