四、GPS天線的性能影響GPS天線性能的主要是以下幾個(gè)方面：1、陶瓷片：陶瓷粉末的好壞以及燒結(jié)工藝直接影響它的性能?，F(xiàn)市面使用的陶瓷片主要是25×25、18×18、15×15、12×12。陶瓷片面積越大，介電常數(shù)越大，其共振頻率越高，接受效果越好。陶瓷片大多是正方形設(shè)計(jì)，是為了保證在XY方向上共振基本一致，從而達(dá)到均勻收星的效果。2、銀層：陶瓷天線表面銀層可以影響天線共振頻率。理想的GPS陶瓷片頻點(diǎn)準(zhǔn)確落在，但天線頻點(diǎn)非常容易受到周邊環(huán)境影響，特別是裝配在整機(jī)內(nèi)，必須通過(guò)調(diào)整銀面涂層外形，來(lái)調(diào)節(jié)頻點(diǎn)重新保持在。因此GPS整機(jī)廠家在采購(gòu)天線時(shí)一定要配合天線廠家，提供整機(jī)樣品進(jìn)行測(cè)試。3、饋點(diǎn)：陶瓷天線通過(guò)饋點(diǎn)收集共振信號(hào)并發(fā)送至后端。由于天線阻抗匹配的原因，饋點(diǎn)一般不是在天線的正**，莆田室外天線，而是在XY方向上做微小調(diào)整。這樣的阻抗匹配方法簡(jiǎn)單而且沒(méi)有增加成本。*在單軸方向上移動(dòng)稱為單偏天線，在兩軸均做移動(dòng)稱為雙偏。4、放大電路：承載陶瓷天線的PCB形狀及面積。由于GPS有觸地反彈的特性，當(dāng)背景是7cm×7cm無(wú)間斷大地時(shí)，patch天線的效能可以發(fā)揮到，莆田室外天線，莆田室外天線。雖然受外觀結(jié)構(gòu)等因素制約，但盡量保持相當(dāng)?shù)拿娣e且形狀均勻。按極化特性,4G天線可分為線極化（垂直極化和水平極化）4G天線、圓極化4G天線和橢圓極化4G天線；莆田室外天線</p><div

不過(guò)實(shí)際生活中，受各種外在條件的限制，譬如天線較長(zhǎng)影響進(jìn)入車庫(kù)，另外為防止磨刮車漆、顛簸脫落，或者使用高增益的較大、較重的天線時(shí)，車載天線往往并沒(méi)有安裝在此位置，而是利用不銹卡鋼座安裝在汽車的行李架、備胎架、前后護(hù)杠、側(cè)面邊框、后備箱蓋甚至排氣管上，更有甚者直接放入車內(nèi)。改變車載天線的位置，實(shí)際上改變的是天線系統(tǒng)的地網(wǎng)，駐波比自然也會(huì)跟著改變。除了車頂正**，在其他位置天線還能調(diào)整到理想的工作狀態(tài)嗎？回答是肯定的，只要安裝時(shí)使用駐波比功率表（即SWR表），或直接使用天線測(cè)試儀，邊測(cè)量邊調(diào)整選擇的位置，保證天線駐波比小于1.5，就完全可以放在車頂以外的其他任意地方。嘉興5G天線天線向電調(diào)化方向開(kāi)展。</p><div
