style="text-indent:25px">玻璃鋼天線(xiàn)有兩大好處抗腐蝕，三高　　高精度、高效率、高增益　　將SMC用于制造天線(xiàn)**重要的作業(yè)就是要從產(chǎn)品設(shè)計(jì)與工藝制作上充分發(fā)揮其特色及達(dá)到天線(xiàn)型高精度的要求。在模具尺度設(shè)計(jì)時(shí)已經(jīng)考慮了資料的收縮率和SMC成型收縮率穩(wěn)定的條件下，SMC天線(xiàn)反射面在成型后違背原設(shè)計(jì)拋物面的形狀較小，即SMC模壓天線(xiàn)的精度完全由模具精度所確保。SMC天線(xiàn)模壓全體反射面均方根值為0.25mm，分瓣天線(xiàn)單片反射面均方根值小于0.3mm，拼裝后反射面均方根值小于0.6mm。　鋁板、鋼板等傳統(tǒng)天線(xiàn)用資料為金屬資料，在耐酸、堿、鹽、以至耐腐蝕性方面，顯有及作為非金屬介質(zhì)復(fù)合資料的SMC。美國(guó)Pikington實(shí)驗(yàn)室用紅外線(xiàn)分析SMC資料的外表，發(fā)現(xiàn)其外表由添加劑、樹(shù)脂、極細(xì)酸鈣填料所覆蓋、具有較好的耐酸、耐水、耐腐蝕性，用此資料制成的天線(xiàn)反射處理了傳統(tǒng)金屬資料天線(xiàn)易腐蝕的缺點(diǎn)，在沿海區(qū)域，多雨，潮濕的區(qū)域以及多酸雨的區(qū)域，SMC模壓天線(xiàn)的這種而腐蝕的優(yōu)點(diǎn)尤顯杰出。美國(guó)波德林公司做過(guò)條件更苛刻的防腐實(shí)驗(yàn)。在50℃的環(huán)境高溫下，將SMC模壓天線(xiàn)試樣置于130種高腐蝕性的化學(xué)品環(huán)境中，結(jié)果表明，實(shí)驗(yàn)樣品*有少許改變，或沒(méi)有改變。</p><p> 4G天線(xiàn)是將高頻電流或波導(dǎo)方式的能量變換成電磁波并向規(guī)則方向發(fā)射出去，或把來(lái)自必定方向的電磁波還原為高頻電流的一種設(shè)備。關(guān)于4G天線(xiàn)，正大信維小編根據(jù)行業(yè)經(jīng)驗(yàn)分享一些基礎(chǔ)知識(shí)給大家。4G天線(xiàn)分類(lèi)：1.按用途分類(lèi)：可分為通訊天線(xiàn)、電視天線(xiàn)、雷達(dá)天線(xiàn)等；2.按作業(yè)頻段分類(lèi)：可分為短波天線(xiàn)、超短波天線(xiàn)、微波天線(xiàn)等；3.按方向性分類(lèi)：可分為全向天線(xiàn)、定向天線(xiàn)等；4.按外形分類(lèi)；可分為線(xiàn)狀天線(xiàn)、面狀天線(xiàn)等.全向天線(xiàn)即在水平方向圖上表現(xiàn)為360°都均勻輻射，也便是平常所說(shuō)的無(wú)方向性，在垂直方向圖上表現(xiàn)為有必定寬度的波束，一般情況下波瓣寬度越小，增益越大。定向天線(xiàn)在水平方向圖上表現(xiàn)為必定角度規(guī)劃輻射，也便是平常所說(shuō)的有方向性，在垂直方向圖上表現(xiàn)為有必定寬度的波束，同全向天線(xiàn)一樣，波瓣寬度越小，增益越大。增益增益是指：在輸入功率持平的條件下，實(shí)際天線(xiàn)與志向的輻射單元在空間同一點(diǎn)場(chǎng)所發(fā)生的信號(hào)的功率密度之比。它定量地描繪一個(gè)天線(xiàn)把輸入功率集中輻射的程度。增益顯著與天線(xiàn)方向圖有親近的聯(lián)絡(luò)，方向圖主瓣越窄，副瓣越小，增益越高。在任何無(wú)線(xiàn)電通信設(shè)備中，總是存在將電磁能輻射到空間并從空間接收電磁能的設(shè)備。</p><div

天線(xiàn)根據(jù)使用場(chǎng)合的不同能夠分為：手持臺(tái)天線(xiàn)、車(chē)載天線(xiàn)、基地天線(xiàn)三大類(lèi)。手持臺(tái)天線(xiàn)便是個(gè)人使用手持對(duì)講機(jī)的天線(xiàn)，常見(jiàn)的有橡膠天線(xiàn)和拉桿天線(xiàn)兩大類(lèi)。車(chē)載天線(xiàn)是指原設(shè)計(jì)安裝在車(chē)輛上通訊天線(xiàn)，**常見(jiàn)使用**普遍的是吸盤(pán)天線(xiàn)。車(chē)載天線(xiàn)結(jié)構(gòu)上也有縮短型、四分之一波長(zhǎng)、中部加感型、八分之五波長(zhǎng)、雙二分之一波長(zhǎng)等方式的天線(xiàn)?；嘏_(tái)天線(xiàn)在整個(gè)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(tái)站。常用的基地臺(tái)天線(xiàn)有玻璃鋼高增益天線(xiàn)、四環(huán)陣天線(xiàn)（八環(huán)陣天線(xiàn)）、定向天線(xiàn)。①按作業(yè)性質(zhì)可分為發(fā)射天線(xiàn)和接收天線(xiàn)。②按用處可分為通訊天線(xiàn)、廣播天線(xiàn)、電視天線(xiàn)、雷達(dá)天線(xiàn)等。③按作業(yè)波長(zhǎng)可分為超長(zhǎng)波天線(xiàn)、長(zhǎng)波天線(xiàn)、中波天線(xiàn)、短波天線(xiàn)、超短波天線(xiàn)、微波天線(xiàn)等。④按結(jié)構(gòu)方式和作業(yè)原理可分為線(xiàn)天線(xiàn)和面天線(xiàn)等。描繪天線(xiàn)的特性參量有方向圖、方向性系數(shù)、增益、輸入阻抗、輻射效率、極化和頻天線(xiàn)按維數(shù)來(lái)分能夠分成兩種類(lèi)型：一維天線(xiàn)由許多電線(xiàn)組成，這些電線(xiàn)或許像手機(jī)上用到的直線(xiàn)，或許是一些靈活的形狀，就像出現(xiàn)電纜之前在電視機(jī)上使用的老兔子耳朵。單極和雙級(jí)天線(xiàn)是兩種**基本的一維天線(xiàn)。二維天線(xiàn)改變多樣，有片狀（一塊正方形金屬）、陣列狀。
