WIFI天線(xiàn)**主要的功用在于變換傳達(dá)介質(zhì)中(一般是空氣介質(zhì))輻射電磁波能量與收發(fā)機(jī)所送出或收到的能量。在能量變換的過(guò)程中，會(huì)出現(xiàn)有收發(fā)機(jī)與WIFI天線(xiàn)及WIFI天線(xiàn)與傳達(dá)介質(zhì)之間的不接連接口。在無(wú)線(xiàn)通訊體系中，WIFI天線(xiàn)有必要按照這兩個(gè)接口的特性來(lái)做恰當(dāng)?shù)囊?guī)劃，以使得收發(fā)機(jī)、WIFI天線(xiàn)以及傳達(dá)介質(zhì)之間構(gòu)成一個(gè)接連的能量傳輸路徑，如此便能夠順暢的將發(fā)射機(jī)的能量藉由發(fā)射WIFI天線(xiàn)輻射到傳達(dá)介質(zhì)中，并藉由接收WIFI天線(xiàn)將輻射電磁波的能量傳送到接收機(jī)端。為了能夠闡明這兩個(gè)接詰母饗釤匭裕?列出了一些主要的參數(shù)，以下就這些參數(shù)的界說(shuō)加以闡明：WIFI天線(xiàn)輸入阻抗(InputImpedance)WIFI天線(xiàn)的輸入阻抗是以收發(fā)機(jī)天線(xiàn)間的接口線(xiàn)端看入到的阻抗值。讓W(xué)IFI天線(xiàn)與收發(fā)電路間到達(dá)阻抗匹配(ImpedanceMatching)以下降因不匹配景象所形成的反射丟失(ReturnLoss)，故WIFI天線(xiàn)的輸入阻抗有必要與收發(fā)機(jī)電路的輸出阻抗相互匹配，如此一來(lái)才不至于使得大部份能量在WIFI天線(xiàn)與收發(fā)機(jī)之間就損耗掉。以一般的WIFI天線(xiàn)規(guī)劃來(lái)說(shuō)，一般輸入阻抗是無(wú)法做大規(guī)模的改動(dòng)。**普遍的規(guī)劃方式是將WIFI天線(xiàn)的輸入阻抗規(guī)劃在一般電路中所常運(yùn)用的50奧姆。</p><p>

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)的就是吸盤(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)。選購(gòu)車(chē)載天線(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。由于吸盤(pán)天線(xiàn)是根據(jù)汽車(chē)使用環(huán)境而設(shè)計(jì)。4G天線(xiàn)的分析是判定給定4G天線(xiàn)結(jié)構(gòu)的方向和阻抗特性。基站天線(xiàn)</p><p
