1、重慶郵電大學(xué)畢業(yè)設(shè)計(jì)（論文）設(shè)計(jì)（論文）題目：應(yīng)用于WLAN/WiMAX的雙頻帶印刷天線設(shè)計(jì)學(xué)院名稱：學(xué)生姓名：專業(yè)：班級(jí)：學(xué)號(hào)：指導(dǎo)教師：答辯組負(fù)責(zé)人：摘要在現(xiàn)在無線通信產(chǎn)業(yè)的飛速發(fā)展下，無線通信行業(yè)正遍布我國的各個(gè)領(lǐng)域，并且競爭也越來越激烈，而作為移動(dòng)通信系統(tǒng)中通信終端的天線要求也就越來越高。伴隨著無線局域網(wǎng)中各項(xiàng)標(biāo)準(zhǔn)的出臺(tái)，因此，研制可同時(shí)適用于多個(gè)頻帶內(nèi)的天線成為天線的設(shè)計(jì)的要求。本文提出了一種應(yīng)用WLAN/WiMAX通信系統(tǒng)的新型雙頻帶印刷天線。通過在微帶板蝕刻對(duì)稱的叉子形輻射貼片和寄生貼片，仿真設(shè)計(jì)了一款雙頻帶印刷天線結(jié)構(gòu)，借助于仿真軟件對(duì)天線進(jìn)行優(yōu)化設(shè)計(jì)，使天線能覆蓋2.4/5.
2、2/5.8GHzWLAN和5.5GHz頻帶，并對(duì)其進(jìn)行了測試。結(jié)果表明，測試結(jié)果和仿真的結(jié)果一樣，并且在帶內(nèi)擁有良好的全向輻射特性。論文共分為五個(gè)部分。首先,論文簡單介紹了無線局域網(wǎng)的基本概念,在了解了無線局域網(wǎng)的的基本知識(shí)后討論了印刷天線發(fā)展情況,最后簡單敘述了本次用的三維仿真軟件。其次,詳細(xì)地回顧了天線的基本理論,包括天線的基本電參數(shù),天線單元的饋電方法等等。接著，介紹了WLAN/WiMAX雙頻帶印刷天線的特點(diǎn)和設(shè)計(jì)特點(diǎn)以及設(shè)計(jì)要求。然后介紹了應(yīng)用于WLAN/WiMAX雙頻帶印刷天線仿真的流程的具體步驟。最后,論文總結(jié)了全部工作,并對(duì)未來相關(guān)研究工作做了適當(dāng)展望。【關(guān)鍵詞】WLAN/WiM
