GPS天線有哪些分類呢？可以根據(jù)不同的維度進(jìn)行分類，下面GPS天線廠家來給您具體介紹一下：1、從極化方式上GPS天線分為垂直極化和圓形極化。以現(xiàn)在的技術(shù)，垂直極化的效果比不上圓形極化。因此除了特殊情況，GPS天線都會(huì)采用圓形極化和線性極化。2、從放置方式上GPS天線分為內(nèi)置天線和外置天線。天線的裝配位置也是十分重要。早期GPS手持機(jī)多采用外翻式天線，此時(shí)天線與整機(jī)內(nèi)部基本隔離，EMI幾乎不對其造成影響，收星效果很好?，F(xiàn)在隨著小型化潮流，GPS天線多采用內(nèi)置，南陽天線。此時(shí)天線必須在所有金屬器件上方，殼內(nèi)須電鍍并良好接地，遠(yuǎn)離EMI干擾源，南陽天線，比如CPU，SDRAM，SD卡，晶振，DC/DC。車載GPS的應(yīng)用會(huì)越來越普遍。而汽車的外殼，特別是汽車防爆膜會(huì)GPS信號產(chǎn)生嚴(yán)重的阻礙。一個(gè)帶磁鐵（能吸附到車頂）的外接天線對于車載GPS來說是非常有必要的。3，南陽天線、從供電方面又分有源和無源。外置式GPS為有源天線，無源天線就是不含LNA放大器，只是天線本體。

實(shí)際上所謂抱負(fù)的全向天線在實(shí)際國際是不存在的，可是在此抱負(fù)的條件下,能夠很簡單核算出在空間的微波功率散布狀況。與發(fā)射功率一樣的一個(gè)實(shí)際的天線的比較大輻射指向方位測得的功率相比，就能夠得出天線的增益. 趁便說一下，前面先生說半波振子是全向天線，增益為1 的說法不必定穩(wěn)當(dāng)，它在H面上是全向的，但在E面上，主瓣半功率寬度為90度，天線增益大于1。4G天線的增益和有源電路的增益是有根本差異的。4G天線增益的丈量測驗(yàn)設(shè)備為信號源，頻譜儀或別的信號接納設(shè)備和點(diǎn)源輻射器。1．先用抱負(fù)（當(dāng)然是近似抱負(fù)）點(diǎn)源輻射天線，參加一功率；然后再距離天線必定的方位上，用頻譜儀或接納設(shè)備測驗(yàn)接納功率。測得的接納功率為P12．換用被測天線，參加一樣的功率，在相同的方位上重復(fù)上述測驗(yàn)，測得接納功率為P2;3．核算增益：G=10Lg(P2/P1)就這樣，得到了天線的增益。</p><p style="text-indent:25px">車載天線是指設(shè)計(jì)安裝在車輛上的移動(dòng)通訊天線，常見的就是吸盤天線。由于吸盤天線安裝擺放容易，所以在一些簡易設(shè)臺(tái)場合常常用吸盤天線代替基地臺(tái)天線。車載天線結(jié)構(gòu)上有縮短型、四分之一波長、中部加感型、八分之五波長、雙二分之一波長等形式的天線，理論上它們的效率依次增加，同樣工作頻段的天線的長度也依次增加。由于車輛本身有限高，加上過長的天線在車輛高速行進(jìn)時(shí)形成的風(fēng)阻，過橋洞、進(jìn)入地下車庫都是問題，所以車載天線并不是越長越好，一般要求轎車天線不超過70厘米，面包車類要求天線更短?？s短型天線體積小巧，雖然增益不高，但適合使用于需要隱蔽天線的場合。一般的警用車輛建議安裝高增天線，尤其是在活動(dòng)區(qū)域范圍比較大的車輛，350MHZ高增益天線多分為八分之五波長加感的形式，在距天線頂部二分之一波長距離處有一個(gè)加感線圈。400MHZ頻段雙二分之一波長天線具有較高的增益，它的外觀特征是天線的振子上有兩個(gè)加感線圈。八分之五波長天線和中部加感型天線也有較高的增益，且價(jià)格比較便宜，因此得到廣的使用。環(huán)形天線和人體非常相似，有普通的單極或多級天線功能。</p><div

無線天線技術(shù)的進(jìn)步帶動(dòng)了飛速發(fā)展的4G時(shí)代，天線成了目前手持終端的一個(gè)瓶頸。目前無論在國內(nèi)手機(jī)天線市場上占有率比較大的老牌天線廠家向移動(dòng)終端轉(zhuǎn)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(shù)難題。淺談4G天線技術(shù)的發(fā)展4G天線技術(shù)即是我們通常說到的第四代移動(dòng)電話行動(dòng)通信標(biāo)準(zhǔn)，指的是第四代移動(dòng)通信技術(shù)，外語縮寫：4G天線技術(shù)。全球移動(dòng)數(shù)據(jù)用戶希望他們的設(shè)備在全球任何地方都能高速聯(lián)網(wǎng)。這種期望給網(wǎng)絡(luò)和設(shè)備性能帶來了巨大的負(fù)擔(dān)。在移動(dòng)數(shù)據(jù)設(shè)備中，天線是“接觸”網(wǎng)絡(luò)的部件，優(yōu)化天線性能變得越來越重要。然而，智能手機(jī)和平板電腦中的4G天線設(shè)計(jì)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(yùn)營商使用不同的制式和使用不同的無線頻段。此外還有藍(lán)牙、WIFI、收音、GPS等。任何一個(gè)與外界的接觸都離不開天線。而現(xiàn)在手機(jī)平板等卻在向輕薄的方向發(fā)展，這給天線所預(yù)留的空間越來越少。我們看看在4G時(shí)代，天線是如何完成這一任務(wù)和挑戰(zhàn)的。4G天線技術(shù)是集3G與WLAN于一體，并能夠快速傳輸數(shù)據(jù)、高質(zhì)量、音頻、視頻和圖像等。4G天線技術(shù)能夠以100Mbps以上的速度下載，比目前的家用寬帶ADSL。GPS天線就是指通過接受衛(wèi)星信號,從而進(jìn)行定位或者導(dǎo)航所用到的天線.影響GPS天線有哪些因素呢？陽江玻璃鋼天線</p><p style="text-indent:25px">車載天線是指設(shè)計(jì)安裝在車輛上的移動(dòng)通訊天線，常見的就是吸盤天線。南陽天線</p><p style="text-indent:25px">車載天線是指設(shè)計(jì)安裝在車輛上的移動(dòng)通訊天線，zui常見就是吸盤天線。由于吸盤天線安裝擺放容易，所以在一些簡易設(shè)臺(tái)場合常常用吸盤天線代替基地天線。車載天線結(jié)構(gòu)上有縮短型、四分之一波長、中部加感型、八分之五波長、雙二分之一波長等形式的天線，理論上它們的效率依次增加，同樣工作頻段的天線的長度也依次增加。由于車輛本身有限高，加上過長的天線在車輛高速行進(jìn)時(shí)形成的風(fēng)阻，過橋洞、進(jìn)入地下車庫都是問題，所以車載天線并不是越長越好，一般要求轎車天線不超過70厘米，面包車類要求天線更短?？s短型天線體積小巧，雖然增益不高，但適合使用于需要隱蔽天線的場合。一般的*車輛建議安裝高增天線，尤其是在活動(dòng)區(qū)域范圍比較大的車輛，350MHZ高增益天線多分為八分之五波長加感的形式，在距天線頂部二分之一波長距離處有一個(gè)加感線圈。400MHZ頻段雙二分之一波長天線具有較高的增益，它的外觀特征是天線的振子上有兩個(gè)加感線圈。八分之五波長天線和中部加感型天線也有較高的增益，且價(jià)格比較便宜，因此得到廣的使用。在作為臨時(shí)固定臺(tái)天線使用的場合可以考慮選用增益高的吸盤天線，天線的長度不必有過多限制。南陽天線</p><p
