4G天線的規(guī)劃面臨著哪些挑戰(zhàn)?有很多要素會(huì)影響手持移動(dòng)通訊設(shè)備的4G天線功用。雖然這些要素是有關(guān)的，但一般可以分紅三大類：天線標(biāo)準(zhǔn)、多副天線之間的互耦以及設(shè)備運(yùn)用模型，揭陽對(duì)講機(jī)天線。天線標(biāo)準(zhǔn)天線標(biāo)準(zhǔn)取決于三個(gè)要素：作業(yè)帶寬、作業(yè)頻率和輻射功率。的帶寬懇求越來越高，其推動(dòng)力來自美國的FCC頻率分配和全球范圍內(nèi)的運(yùn)營商周游協(xié)議；不相同區(qū)域運(yùn)用不相同的頻段。‘帶寬和天線標(biāo)準(zhǔn)是直接有關(guān)的’且‘功率和天線標(biāo)準(zhǔn)是直接有關(guān)的’--這一般意味著，更大標(biāo)準(zhǔn)的天線可以供給更大的帶寬和更高的功率。除了帶寬外，天線標(biāo)準(zhǔn)還取決于作業(yè)頻率。在北美區(qū)域，運(yùn)營商VerizonWireless和AT&TMobility挑選推廣的LTE商品作業(yè)在700MHz頻段，這在幾年前是FCCUHF-TV再分配頻段的一部分。這些新的頻段（17，704－746MHz和13，746－786MHz）比北美運(yùn)用的傳統(tǒng)蜂窩頻段（5，824－894MHz）要低。這個(gè)改變是無窮的，因?yàn)轭l率越低，波長越長，因此需求更長的天線才干堅(jiān)持輻射功率不變。為了保證輻射功率，天線標(biāo)準(zhǔn)有必要做大，揭陽對(duì)講機(jī)天線。但是，設(shè)備體系規(guī)劃人員還需求增加更大的顯示器和更多的功用，揭陽對(duì)講機(jī)天線，因此可用的天線長度和悉數(shù)體積遭到極大束縛，然后降低了天線帶寬和功率。八木定向天線，具有增益較高、結(jié)構(gòu)輕巧、架設(shè)方便、價(jià)格便宜等優(yōu)點(diǎn)；揭陽對(duì)講機(jī)天線</p><div

車載天線應(yīng)該如何選購？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(chǎng)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(chǎng)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。在作為臨時(shí)固定臺(tái)天線使用的場(chǎng)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。鹽城橡膠天線按外形分類，可分為線狀天線、面狀天線等分類。</p><div
