電場(chǎng)集中在電容器的兩個(gè)極板之中，而磁場(chǎng)則分布在電感線(xiàn)圈的有限空間里，電磁波顯然不能向廣闊空間輻射。如果將振蕩電路展開(kāi)，使電磁場(chǎng)分布于空間很大的范圍，這就創(chuàng)造了有利于輻射的條件;于是，船舶天線(xiàn)廠家，來(lái)自發(fā)信機(jī)的、已調(diào)制的高頻信號(hào)電流由饋線(xiàn)送到天線(xiàn)上，并經(jīng)天線(xiàn)把高頻電流能量轉(zhuǎn)變?yōu)橄鄳?yīng)的電磁波能量，向空間輻射。電磁波的能量從發(fā)信天線(xiàn)輻射出去以后，將沿地表面所有方向向前傳播。若在交變電磁場(chǎng)中放置一導(dǎo)線(xiàn)，由于磁力線(xiàn)切割導(dǎo)線(xiàn)，船舶天線(xiàn)廠家，就在導(dǎo)線(xiàn)兩端激勵(lì)一定的交變電壓——電動(dòng)勢(shì)，其頻率與發(fā)信頻率相同。若將該導(dǎo)線(xiàn)通過(guò)饋線(xiàn)與收信機(jī)相連，在收信機(jī)中就可以獲得已調(diào)波信號(hào)的電流。因此，這個(gè)導(dǎo)線(xiàn)就起了接收電磁波能量并轉(zhuǎn)變?yōu)楦哳l信號(hào)電流能量的作用，船舶天線(xiàn)廠家，所以稱(chēng)此導(dǎo)線(xiàn)為收信天線(xiàn)。無(wú)論是發(fā)信天線(xiàn)還是收信天線(xiàn)，它們都屬于能量變換器，“可逆性”是一般能量變換器的特性。同樣一副天線(xiàn)，它既可作為發(fā)信天線(xiàn)使用，也可作為收信天線(xiàn)使用，通信設(shè)備一般都是收、發(fā)共同用一根天線(xiàn)。因此，同一根天線(xiàn)既關(guān)系到發(fā)信系統(tǒng)的有效能量輸出，又直接影響著收信系統(tǒng)的性能。天線(xiàn)的可逆性不*表現(xiàn)在發(fā)信天線(xiàn)可以用作收信天線(xiàn)，收信天線(xiàn)可以用作發(fā)信天線(xiàn)，并且表現(xiàn)在天線(xiàn)用作發(fā)信天線(xiàn)時(shí)的參數(shù)。天線(xiàn)問(wèn)題可以理解為檢查由電磁波激勵(lì)源產(chǎn)生的電磁響應(yīng)特性。船舶天線(xiàn)廠家</p><div

汽車(chē)天線(xiàn)如何保養(yǎng)？1、洗車(chē)順便擦天線(xiàn)每次洗車(chē)的時(shí)候，順便把天線(xiàn)擦拭一下。把汽車(chē)天線(xiàn)核拉出來(lái)，擦掉上面的灰塵和臟東西，然后把它擦干。2、檢查天線(xiàn)必須和車(chē)身鈑金結(jié)合要想收音效果好，則天線(xiàn)必須和車(chē)身鈑金密切地接合。有時(shí)候甚至只有一點(diǎn)銹也會(huì)造成收音不良。所以要定期檢查天線(xiàn)的底座，并且做清理。首先要松開(kāi)天線(xiàn)底座的螺母。把飯金上的洞口和天線(xiàn)底部的銹用砂紙或小鋼刷除掉，擦拭干凈后，檢查一下天線(xiàn)和鈑金之間的墊片是不是完整，有沒(méi)有老化。另外天線(xiàn)桿身螺紋上的銹也要清一清.等一切都搞定之后，把天線(xiàn)依序上緊，但不要上得太緊.以免把螺紋旋壞，或者把鈑金洞口部位搞得變形。檢查天線(xiàn)和收音機(jī)兩端所有的線(xiàn)頭和接頭，除掉所有的灰塵與污垢，糾正所有接觸不良或者沒(méi)有插緊的地方。以上所有內(nèi)容就是汽車(chē)天線(xiàn)的安裝和保養(yǎng)方法，大家所了解的汽車(chē)天線(xiàn)是一個(gè)靜電釋放器，主要是將行駛中汽車(chē)外殼積聚的靜電釋放出來(lái)，保護(hù)乘員安全和汽車(chē)電路。一根小小的汽車(chē)天線(xiàn)，同時(shí)具備了數(shù)字廣播、移動(dòng)電視、GPS導(dǎo)航和語(yǔ)言識(shí)別等多種功能，用于接收和加強(qiáng)收音信號(hào),目前的我國(guó)大部分地區(qū)信號(hào)多很弱,汽車(chē)還需外置天線(xiàn),在信號(hào)不穩(wěn)定的地區(qū)有很大的幫助。東莞對(duì)講機(jī)天線(xiàn)車(chē)載天線(xiàn)是攔截發(fā)射臺(tái)發(fā)射的高頻電波并傳輸給車(chē)載收音機(jī)、車(chē)載電話(huà)或無(wú)線(xiàn)電導(dǎo)航設(shè)備的接收機(jī)；</p><div

WIFI天線(xiàn)也就是常說(shuō)的天線(xiàn)無(wú)線(xiàn)路由器。無(wú)線(xiàn)路由器范圍包括單天線(xiàn)、雙天線(xiàn)和三天線(xiàn)后續(xù)還有多天線(xiàn)路由器。**近正大信維小編有遇到一些客戶(hù)咨詢(xún)wifi天線(xiàn)的天線(xiàn)數(shù)量不同的區(qū)別有哪些，下面我們就來(lái)具體看一下。1、雙天線(xiàn)和單天線(xiàn)區(qū)別在是雙發(fā)雙收，還是單發(fā)單收，前者局域網(wǎng)速度是300M，后者局域網(wǎng)一般是150M。雙天線(xiàn)路由器在使用時(shí)比較好不要讓兩條天線(xiàn)平行，了兩者比較好成135度張角，即一條天線(xiàn)與桌面垂直，另一條與桌面成45度角。2、單天線(xiàn)路由、雙天線(xiàn)路由、三線(xiàn)四線(xiàn)有區(qū)別，但對(duì)于實(shí)際使用過(guò)程中的影響并不大，這包括信號(hào)覆蓋、信號(hào)強(qiáng)度，天線(xiàn)多速度快就更是無(wú)稽之談了。拋開(kāi)已經(jīng)很少見(jiàn)的單天線(xiàn)，剩下的“多天線(xiàn)”都只是實(shí)現(xiàn)MIMO技術(shù)的“介質(zhì)”或者說(shuō)是“工具”，區(qū)別在于使用的架構(gòu)不同而已：常見(jiàn)的雙天線(xiàn)產(chǎn)品主要用1T2R或2T2R，三天線(xiàn)產(chǎn)品則用到的是2T3R或3T3R。理論上，增加天線(xiàn)數(shù)量會(huì)減少信號(hào)覆蓋盲點(diǎn)，但我們通過(guò)大量的評(píng)測(cè)證實(shí)，這種差異在普通家庭環(huán)境中完全可以忽略不計(jì)。而且，就像內(nèi)置天線(xiàn)不輸外置一樣，三天線(xiàn)覆蓋不如雙天線(xiàn)的情況也絕非個(gè)例，說(shuō)到底產(chǎn)品質(zhì)量也是一個(gè)重要因素。至于信號(hào)強(qiáng)度和“穿墻”則取決于發(fā)射功率，這個(gè)東西工信部作過(guò)規(guī)定。</p><p> 3G天線(xiàn)有哪些類(lèi)型在無(wú)線(xiàn)局域網(wǎng)里，多見(jiàn)的設(shè)備有無(wú)線(xiàn)網(wǎng)卡、無(wú)線(xiàn)網(wǎng)橋、無(wú)線(xiàn)3G天線(xiàn)等。1、無(wú)線(xiàn)網(wǎng)卡無(wú)線(xiàn)網(wǎng)卡的作用類(lèi)似于以太網(wǎng)中的網(wǎng)卡，作為無(wú)線(xiàn)局域網(wǎng)的接口，完結(jié)與無(wú)線(xiàn)局域網(wǎng)的聯(lián)接。無(wú)線(xiàn)網(wǎng)卡依據(jù)接口類(lèi)型的不一樣，首要分為三種類(lèi)型，即PCMCIA無(wú)線(xiàn)網(wǎng)卡、PCI無(wú)線(xiàn)網(wǎng)卡和USB無(wú)線(xiàn)網(wǎng)卡。PCMCIA無(wú)線(xiàn)網(wǎng)卡*適用于筆記本電腦，支撐熱插拔，可以非常方便地完結(jié)移動(dòng)無(wú)線(xiàn)接入。PCI無(wú)線(xiàn)網(wǎng)卡適用于一般的臺(tái)式計(jì)算機(jī)運(yùn)用。原本PCI無(wú)線(xiàn)網(wǎng)卡只是在PCI轉(zhuǎn)接卡上刺進(jìn)一塊一般的PCMCIA卡。USB接口無(wú)線(xiàn)網(wǎng)卡適用于筆記本和臺(tái)式機(jī)，支撐熱插拔，假設(shè)網(wǎng)卡外置有無(wú)線(xiàn)3G天線(xiàn)，那么，USB接口即是一個(gè)比較好的選擇。2、無(wú)線(xiàn)網(wǎng)橋從作用上來(lái)了解無(wú)線(xiàn)網(wǎng)橋，它可以用于聯(lián)接兩個(gè)或多個(gè)**的網(wǎng)絡(luò)段，這些**的網(wǎng)絡(luò)段通常位于不一樣的建筑內(nèi)，相距幾百米到幾十公里。所以說(shuō)它可以廣泛應(yīng)用在不一樣建筑物間的互聯(lián)。一同，依據(jù)協(xié)議不一樣，無(wú)線(xiàn)網(wǎng)橋又可以分為。無(wú)線(xiàn)網(wǎng)橋有三種工作方式，點(diǎn)對(duì)點(diǎn)，點(diǎn)對(duì)多點(diǎn)，中繼聯(lián)接。特別適用于城市中的遠(yuǎn)距離通訊．在無(wú)巨大妨礙（山峰或建筑）的條件下，一對(duì)速組網(wǎng)和野外作業(yè)的暫時(shí)組網(wǎng)。其作用距離取決于環(huán)境和3G天線(xiàn)，現(xiàn)7km的點(diǎn)對(duì)點(diǎn)微波互連。外置天線(xiàn)作用于路由器，機(jī)頂盒，基站，攝像頭等等；</p><div

style="text-indent:25px">??車(chē)載天線(xiàn)是指設(shè)計(jì)安裝在車(chē)輛上的移動(dòng)通訊天線(xiàn)，**常見(jiàn)就是吸盤(pán)天線(xiàn)。由于吸盤(pán)天線(xiàn)安裝擺放容易，所以在一些簡(jiǎn)易設(shè)臺(tái)場(chǎng)合常常用吸盤(pán)天線(xiàn)代替基地臺(tái)天線(xiàn)。車(chē)載天線(xiàn)結(jié)構(gòu)上有縮短型、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)等形式的天線(xiàn)，理論上它們的效率依次增加，同樣工作頻段的天線(xiàn)的長(zhǎng)度也依次增加。　　 ?? 由于車(chē)輛本身有限高，加上過(guò)長(zhǎng)的天線(xiàn)在車(chē)輛高速行進(jìn)時(shí)形成的風(fēng)阻，過(guò)橋洞、進(jìn)入地下車(chē)庫(kù)都是問(wèn)題，所以車(chē)載天線(xiàn)并不是越長(zhǎng)越好，一般要求轎車(chē)天線(xiàn)不超過(guò)70厘米，面包車(chē)類(lèi)要求天線(xiàn)更短。　? ?? 縮短型天線(xiàn)體積小巧，雖然增益不高，但適合使用于需要隱蔽天線(xiàn)的場(chǎng)合。一般的警用車(chē)輛建議安裝高增天線(xiàn)，尤其是在活動(dòng)區(qū)域范圍比較大的車(chē)輛，350MHz高增益天線(xiàn)多分為八分之五波長(zhǎng)加感的形式，在距天線(xiàn)頂部二分之一波長(zhǎng)距離處有一個(gè)加感線(xiàn)圈。　　 ?? 400MHz頻段雙二分之一波長(zhǎng)天線(xiàn)具有較高的增益，它的外觀特征是天線(xiàn)的振子上有兩個(gè)加感線(xiàn)圈。八分之五波長(zhǎng)天線(xiàn)和中部加感型天線(xiàn)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(xiàn)使用的場(chǎng)合可以考慮選用增益高的吸盤(pán)天線(xiàn)，天線(xiàn)的長(zhǎng)度不必有過(guò)多限制。天線(xiàn)不可放在室內(nèi)使用，同時(shí)也造成高駐波。還有害人體。東莞對(duì)講機(jī)天線(xiàn)</p><p
