style="text-indent:25px">5G時代臨近，全球多國**和組織、學術界與工業(yè)界均已開始開展5G原型系統(tǒng)與關鍵技術的研發(fā)，預計將于2020年進入商業(yè)化部署階段，屆時可實現高達10?Gbit/s的傳輸速率、1000倍的系統(tǒng)容量提升和千億設備的連接，以滿足移動互聯網和物聯網高速發(fā)展對移動數據業(yè)務的需求。與2G、3G和4G技術的演進相比，5G技術不**是追求傳輸速率的提升，而且是與各個垂直行業(yè)的應用相互結合，大帶寬高速率、低時延高可靠、低功耗大連接等5G技術特點在不同行業(yè)中將有不同的需求，5G的行業(yè)推進一定不是技術驅動的產物，而是應用驅動的結果。目前，5G通信系統(tǒng)要實現速率和系統(tǒng)容量的提升，需通過開發(fā)新頻譜資源、提高頻譜效率和布置超密集網絡等途徑實現，因此需要開發(fā)新的無線傳輸技術來滿足以上需求。毫米波頻段（30GHz-300GHz）具有較豐富的頻譜資源，能夠提供較大的信號帶寬，同時在毫米波頻段采用波束賦形（Beam forming）技術可以有效地克服毫米波傳輸問題，從而擴展毫米波通信的距離。 </p><p> 無線天線技術的進步帶動了飛速發(fā)展的4G時代，天線成了目前手持終端的一個瓶頸。目前無論在國內手機天線市場上占有率比較大的老牌天線廠家向移動終端轉型的一些**，所面臨的都是4G天線所帶來的巨大挑戰(zhàn)。下面我們來探討一下是哪些原因造成了這一技術難題。淺談4G天線技術的發(fā)展4G天線技術即是我們通常說到的第四代移動電話行動通信標準，指的是第四代移動通信技術，外語縮寫：4G天線技術。全球移動數據用戶希望他們的設備在全球任何地方都能高速聯網。這種期望給網絡和設備性能帶來了巨大的負擔。在移動數據設備中，天線是“接觸”網絡的部件，優(yōu)化天線性能變得越來越重要。然而，智能手機和平板電腦中的4G天線設計所面臨的挑戰(zhàn)十分艱巨。在中國，我們常說五模十頻。就是指不同運營商使用不同的制式和使用不同的無線頻段。此外還有藍牙、WIFI、收音、GPS等。任何一個與外界的接觸都離不開天線。而現在手機平板等卻在向輕薄的方向發(fā)展，這給天線所預留的空間越來越少。我們看看在4G時代，天線是如何完成這一任務和挑戰(zhàn)的。4G天線技術是集3G與WLAN于一體，并能夠快速傳輸數據、高質量、音頻、視頻和圖像等。4G天線技術能夠以100Mbps以上的速度下載，比目前的家用寬帶ADSL。按外形分類，可分為線狀天線、面狀天線等分類；</p><div

車載天線是指原設計安裝在車輛上通訊天線，**常見使用**普遍的是吸盤天線。車載天線結構上也有縮短型、四分之一波長、中部加感型、八分之五波長、雙二分之一波長等方式的天線。基地臺天線在整個通訊體系中具有十分要害的效果，尤其是作為通訊紐帶的通訊臺站。常用的基地臺天線有玻璃鋼高增益天線、四環(huán)陣天線（八環(huán)陣天線）、定向天線。據上所述。影響天線效果的有。天然物體，如山、樹、房子等。還有便是天氣，由于云層會對天線有反射效果。其次是天線的彼此干擾。**終是其它的電磁干擾，如手機信號塔，電視信號塔，廣播信號塔。
