Tanthauzo la mlongoti wa maginito
Tiyeni tiyankhule za kapangidwe ka mlongoti wa maginito, mlongoti wamba wamsika pamsika umapangidwa makamaka ndi: antenna radiator, sucker yamphamvu yamaginito, feeder, mawonekedwe a antenna a zidutswa zinayi izi.
1, zida za radiator ya mlongoti ndi chitsulo chosapanga dzimbiri, mkuwa weniweni, aloyi yokumbukira ndi zinthu zina, mawonekedwe ake nthawi zambiri amakhala chikwapu kapena ndodo.Themaginito antennaradiator kwenikweni ndi unipolar (chikwapu) mlongoti, amene ndi symmetric oscillator ndi mkono umodzi perpendicular kwa kondakitala ndege yabwino (pansi).Malinga ndi mfundo ya mlongoti, ma frequency omveka a mlongoti wa waya ndi gawo lophatikizika la 1/2 wavelength, ndipo malinga ndi mfundo yagalasi, pa ndege yabwino yopanda malire, kukula kwamagetsi kocheperako kwa mlongoti wa maginito ndi 1/4 wavelength. , ndipo ngati phindu liyenera kukonzedwa, kukweza kwapakati kungagwiritsidwe ntchito kuonjezera kutalika kwa radiator ya mlongoti (1/4 wavelength integral multiple).
2, udindo wa chuck wamphamvu wa maginito ndikukonza mlongoti wonse ndikuwonetsetsa kuti mlongoti wa chuck wakhudzana ndi chitsulo chomwe chikuyamwa.
3, chodyetsa nthawi zambiri ndi RG mndandanda (RG58, RG174), waya wa 3D ndi zina zotero.
4, mawonekedwe a mlongoti wamba ndi awa: N mutu, SMA, BNC, TNC, I-PEX ndi mitundu ina ya mawonekedwe, mwa omwe maginito omwe amagwiritsidwa ntchito kwambiri ndi N mutu, SMA, BNC, TNC, etc., amuna ndi akazi, sankhani mlongoti uyenera kugula cholumikizira chomwe chikufanana ndi zida.
Mfundo zazikuluzikulu zogwiritsira ntchito maginito antenna
Kuti ndikufotokozereni, chifukwa chiyani mbale yoyamwa imamatira kuchitsulo?
Kuchokera ku ma tweets athu akale, tikhoza kudziwa kuti magetsi a mlongoti amagwirizana kwambiri ndi malo omwe amagwiritsidwa ntchito, ndipo ma frequency a resonant amakhudzidwa ndi kusinthasintha kwa dielectric kwa zinthu kuzungulira mlongoti, ndipo kugwiritsa ntchito kwake ndi ntchito yake sikungatheke. kulekanitsidwa ndi zofuna za chilengedwe ndi malo oyika.
Radiyeta ya mlongoti woyamwa wotchulidwa pamwambapa ndi mlongoti wa unipolar.Malinga ndi mfundo yachifanizo, mlongoti wa unipolar wokhala ndi kutalika kwa h ndi chithunzi chake umapanga oscillator symmetric ndi kutalika kwa 2h, omwe munda wawo kumtunda wa theka ndi wofanana ndi wa oscillator symmetric, ndi mphamvu ya m'munda m'munsi mwa danga. ziro
Nthawi zambiri, mlongoti wa maginito umagwiritsidwa ntchito makamaka mu nduna, padenga la galimoto kapena malo ofanana, motero amapangidwa pamaziko amitundu yosiyanasiyana ya nduna ndi magalimoto, kotero kuti kukula kwa chitsulo pansi pa gawo la wailesi. kutalika kwa mafupipafupi a kulumikizana kumakhala gawo la mlongoti.Chifukwa chake, kuyika kosiyanasiyana kumakhudza mwachindunji kusintha kwa mapangidwe amagetsi a mlongoti, makamaka ma frequency a resonant ndi mayendedwe a radiation.
Chithunzi chowongolera ma radiation cha antenna ya unipolar ya kotala limodzi pagawo lomaliza (pogwiritsa ntchito, diski yachitsulo yokhazikika imakhala yocheperako ndipo siyingapange chithunzi chonse chagalasi), komanso pali ma radiation m'munsi mwa theka (diffraction effect). ).
Kagwiridwe ka mlongoti wa maginito sucker ndi wosiyana kotheratu ukakhala adsorbed pa zitsulo thupi la makulidwe osiyanasiyana.Chifukwa chake, mukamagwiritsa ntchito mlongoti woyamwa, timalimbikitsa mfundo ziwiri izi:
1, imayenera kuyikidwa pamwamba pa nduna kapena locomotive kuti zitsimikizire kutalika ndi kuwongolera kwa radiation, kuti muzitha kusewera bwino kwambiri mlongoti;Ngati itayikidwa m'magawo ena, imayambitsa kusintha kwa mafunde oyimirira, mawonekedwe owongolera ndi Angle yokwera, zomwe zimakhudza kulumikizana.
2, momwe mungathere kukhazikitsa mlongoti m'mbali zambiri za masomphenya, pewani kuyika muzitsulo kapena malo ovuta a electromagnetic, mwa njira iyi yokha yomwe ingasinthire kulankhulana, kuchepetsa phokoso lakumbuyo ndi zochitika zina zosayembekezereka zosokoneza.
Kugwiritsa ntchito maginito mlongoti
Pankhani yogwiritsa ntchito tinyanga ta maginito, tiyeni tiyambe takambirana za ubwino wake.Ikayikidwa bwino, mlongoti woyamwa umakhala ndi mafunde abwino oyimirira komanso magwiridwe antchito apamwamba kuposa mlongoti womangidwa, ndipo palibe kusintha komwe kumafunikira.Ndi mlongoti wa glue womwewo mu gulu la ma frequency ndi kukula kwake, kupindula ndikwambiri, mtunda wotumizira ndi wautali, ndipo malo osiyanasiyana oyika amatha kusankhidwa malinga ndi zosowa zenizeni.
Kuphatikiza pa zabwino zomwe tafotokozazi, antenna yoyamwitsa imakhalanso ndi ntchito zambiri, kuphatikizapo makina athu ogulitsa tsiku ndi tsiku, makabati owonetsera, wailesi yamagalimoto, angagwiritsidwenso ntchito ku ma modules opanda zingwe ndi zipata zopanda zingwe zokhala ndi zofunikira zopindula.
Mlongoti wa maginito ukhoza kugwiritsidwa ntchito mu bokosi lamagetsi lakunja, galimoto.Akagwiritsidwa ntchito panja, radome ikhoza kupangidwa ndi fiberglass ndi zipangizo zina, zomwe zingakhale zopanda madzi komanso mphepo.
Mlongoti wa maginito ungagwiritsidwenso ntchito m'makina ogulitsa, m'munsi mwa mlongoti ndi sucker yamphamvu ya maginito, yosavuta kuyiyika, yosavuta kugwa.
Mlongoti wa maginito ungagwiritsidwenso ntchito powerenga mita opanda zingwe, kapangidwe ka mlongoti ndi kopepuka, kokongola
