Mfundo yolumikizirana ndi zida,
Kodi mungatumizire bwanji bwino ndi kufalitsa zizindikiro za 3G / 4G chizindikiro chobwerezabwereza?

Choyamba, mfundo ya antenna:
1.1 Tanthauzo la Antenna:
Chida chomwe chimatha kukhala bwino pamagetsi owongolera kutsogoleredwa m'malo mwapadera kapena amatha kulandira mafunde a elekitikiti kuchokera kumbali inayake.
1.2 Antenna Ntchito:
Kutembenuka kwa mphamvu - kutembenuka kwa funde lotsogozedwa ndi funde laulere; Ma radiation owongolera (phwando) - ali ndi chizolowezi china.

M'lifupi mwake
Front Kutsogolo Kumbuyo: kumanenanso kuchuluka kwa mphamvu yolumikizidwa ndi antenna ndi mphamvu zodzikuza kumbuyo mkati mwa ± 30 °.
Ubale womwe uli pakati pa zopindulitsa ndi mawonekedwe a antetena ndi zokongola
Kuyamwa "Turo", kukwiya kwambiri, kupeza phindu, kukula kwake, kukula kwake kwakukulu, ndi kanjeme kakang'ono kwambiri;
Mfundo zazikuluzikulu za Antenna Kupeza:
Antenna ndi chipangizo chongokhalira ndipo simungathe kupanga mphamvu. Kupeza kwa Antenna ndikungotha kugwiritsa ntchito mphamvu zambiri kutentha kapena kulandira mafunde elekitomagnetic munjira inayake.
Ø Kuchuluka kwa antenna kumapangidwa chifukwa cha ma ristirators. Kukula kwapamwamba, kutalika kwakutali. Onjezerani phindu ndi 3db ndikuwonjezera voliyumu.
Kupeza mwayi wapamwamba, kukhala wabwino kwambiri, womwe umakhazikika kwambiri mphamvu, komanso wonenepa kwambiri lobe.
1.5 ma radiation
Polarization: amatanthauza kusokonekera kapena kusintha kwa verction yamagetsi m'malo.
1.6 magawo ozungulira
Kubwezeretsanso
Zinthu ziwiri, nyerete
2.1 Njira Yopatsirana:
Magulu a Antenna: Odp (pordoor potenna), OOA (panja omnidiirectional antenna), OCS (panja (kunja yaagi antenna), panja Iwh (khoma lolowera ku Antenna) ndi zina.
Hafu yamphamvu:
Polarization Mode: R (polarization), v (polarization imodzi)
Pezani: mtengo wokwanira kwambiri ndi 21dbi potengera mtengo weniweni
Mitundu yolumikizana: D (mutu wa dina), N (N-N-N-N-N-N-N-N-N-N
Gulu la pafupipafupi:
Khodi yofotokozera: zilembo za Roma zikuwonetsa m'badwo wa malonda. Makalata otsatirawa ndi manambala amawonetsa kuti paliponse, mawonekedwe, ndi zidziwitso zina. F mtundu; Vlamu yamalamulo; RV imayambira kusintha magetsi

3.1 Wogulitsa Magetsi
Wogulitsa magetsi ndi chipangizo chomwe chimagawa mphamvu imodzi yotulutsa chimodzi kapena zingapo zotulutsa. Ndiko kutembenuka mtima.
Kodi woyang'anira mphamvu angathe kusinthidwa kuti asinthe cotsa?
Mukamagwiritsidwa ntchito ngati kaphatikizidwe, sizimangofuna kudzipatula kwambiri, chiwerengero chotsika chotsika, komanso chimangoyang'ana kofunikira kuti lithe kupirira mphamvu zambiri. Poona kuti madoko osindikizira omwe amagwiritsidwa ntchito nthawi zambiri amagwiritsa ntchito slider osagwirizana, funde lalikulu lamanzere; Chifukwa cha kukana kwamphamvu kwa mpweya wa micrestript, sitikulimbikitsa kugwiritsa ntchito gawo lamphamvu kuti tisinthe.
Pambale yamagetsi
Zinayi, mawu oyamba
4.1
Ø Banja ndi mtundu wa chinthu chomwe chimagawa mphamvu ya chizindikiro kudzera mu minda yamagetsi ndi maginito kuti zikhale gawo la zotulukapo zotulutsa, ndipo zotsirizira zonse zomwe zidatulutsa kuti zithe kufalitsa mphamvu.
Kugawidwa kwamphamvu kwa okwatirana sikugawana chimodzimodzi. Amadziwikanso kuti ndi mphamvu.
Zogwirizana
Makina oyendetsedwa ndi njira nthawi zambiri amagwiritsidwa ntchito ndi njira yoyendetsedwa ndi ma microwave signaves ya ma microwave, cholinga chachikulu ndikusiyanitsa ndi kusakaniza chizindikiro, kapena kupatula katundu wa mkati, omwe sakhala nawo padokoni anayi.
Caledle
Mawonekedwe: Kuvala mphamvu zambiri, kutaya kochepa.
Chifukwa chake:
1. Patsekelo zimadzaza ndi mpweya, ndipo munjira yofalikitsa, kufalikira kwa media komwe kumayambitsidwa ndi sing'anga ya mpweya.
2. Lamba wophatikizidwa nthawi zambiri amapangidwa ndi wochititsa ndi zamagetsi (monga mawonekedwe asiliva abwino (monga omwe ali ndi siliva pamkuwa), ndipo kutayika kwa wopondera sikungatheke.
3. UTHENGA waukulu, voliyumu yayikulu, kupumira msanga. Kupirira mphamvu zambiri.

Ø ATNENUARE NDI CHITSANZO CHOKHA CHOKHA
Odziwa bwino kwambiri ndi mayamwidwe.
Kuchulukitsa kwa coaxial nthawi zambiri kumagwiritsidwa ntchito mu ukadaulo, wokhala ndi "π" kapena "t" yolumikizira.
Ogwirizana ndi ogwirizana nthawi zambiri amakhala ndi mitundu iwiri ya okhazikika komanso osiyanasiyana.
Ø Onyozedwa amagwiritsidwa ntchito makamaka kuwongolera upangiri wa microwave zizindikiro zam'madzi ndikugwiritsa ntchito mphamvu zowonjezera, monga oyang'anira magetsi, oyang'anira, olandila, ndi ena oterowo.
