Yiziphi izinhlobo zezimpondo ezikhona?

 Isigaba se-Antenna

I-antenna iyisisetshenziswa esikhipha amasignali efrikhwensi yomsakazo isuka entanjeni yokudlulisela iye emoyeni noma iwamukele isuka emoyeni iye entanjeni yokudlulisela.Kungabuye kubhekwe njengesiguquli se-impedance noma isiguquli samandla.Guqula ube amagagasi kazibuthe kagesi asakazeka endaweni engenamkhawulo, noma okuphambene nalokho.Ngokuklanywa kwedivayisi ye-transceiver engenantambo esetshenziswa ohlelweni lwefrikhwensi yomsakazo, ukwakheka nokukhethwa kothi kuyingxenye ebalulekile yalo.Uhlelo oluhle lwe-antenna lungafinyelela ibanga elingcono kakhulu lokuxhumana.Usayizi wohlobo olufanayo lwe-antenna ulingana nobude bezasi besignali yefrikhwensi yomsakazo.Lapho i-frequency iphansi, i-antenna iyadingeka.

Ama-antenna angahlukaniswa abe izimpondo zangaphandle kanye nezimpondo ezakhelwe ngaphakathi ngokuya ngendawo yokufaka.Lezo ezifakwe ngaphakathi ocingweni zibizwa ngokuthi izimpondo ezakhelwe ngaphakathi, futhi lezo ezifakwe ngaphandle kwedivayisi zibizwa ngokuthi izimpondo zangaphandle.Emikhiqizweni emincane efana nemishini ephathwayo, imiklamo egqokekayo, namakhaya ahlakaniphile, izinti ezakhelwe ngaphakathi zivame ukusetshenziswa, ezinokuhlanganiswa okuphezulu nokubukeka okuhle.I-inthanethi Yezinto kanye nemikhiqizo ye-smart hardware idinga ukudlulisa idatha ku-inthanethi, ngakho bonke badinga ukusebenzisa izinti.

Uma isikhala sincane kanye namabhendi efrikhwensi, kuba nzima nakakhulu ukuklama kothi.Izimpondo zangaphandle ngokuvamile ziyimikhiqizo evamile.Ungasebenzisa izinti kumabhendi amafrikhwensi adingekayo ngaphandle kokulungisa iphutha, vele uxhume futhi udlale.Isibonelo, amakhabethe avezayo, imishini yokuthengisa, njll., ngokuvamile asebenzisa izinti zangaphandle kazibuthe, ezingamuncwa egobolondweni lensimbi.Lawa ma-antenna awakwazi ukubekwa ekhabetheni lensimbi, futhi insimbi izovikela isignali ye-antenna, ngakho-ke ingabekwa ngaphandle kuphela.Le ndatshana igxile ekuhlukaniseni nasekukhetheni indlela yothi, futhi yethula ulwazi olufanele lwe-antenna.

1. I-Antenna yangaphandle 

Ama-antenna angaphandle angahlukaniswa abe izimpondo ze-omnidirectional kanye nezimpondo eziqondisayo ngokuya ngama-engeli emisebe ahlukene enkundla yemisebe.

i-antenna ye-omnidirectional

Ama-antenna e-Omnidirectional, okungukuthi, imisebe efanayo engu-360° kuphethini evundlile, okungukuthi, lokho okubizwa ngokuthi akukho-isiqondiso, kanye ne-beam enobubanzi obuthile kuphethini eqondile.Ngokuvamile, ububanzi be-lobe buncane, Ukuzuza okukhulu.

I-antenna eqondisayo

I-antenna eqondisayo isho uthi oludlulisa futhi lwamukele amagagasi kagesi endaweni eyodwa noma ezimbalwa eziqondile ezinamandla ngokukhethekile, kuyilapho ukudlulisa nokwamukela amagagasi kagesi kwezinye izindawo kunguziro noma kuncane kakhulu.Inhloso yokusebenzisa i-antenna eqondisayo iwukuba kukhuliswe ukusetshenziswa okusebenzayo kwamandla omsakazo kanye nokwandisa ubumfihlo;inhloso eyinhloko yokusebenzisa uthi oluqondisayo olwamukelayo ukuthuthukisa amandla esignali nokwandisa ikhono lokulwa nokuphazamiseka.Ama-antenna angaphandle aqondisayo ikakhulukazi afaka izimpondo zephaneli eyisicaba, izimpondo ze-Yagi kanye nezimpondo ze-logarithmic periodic.

2.I-antenna eyakhelwe ngaphakathi

 I-Antenna eshumekiwe ibhekisa kakhulu etemini elijwayelekile lezimpondo ezingafakwa ngaphakathi kwedivayisi.Izimpondo ezakhelwe ngaphakathi ikakhulukazi zihlanganisa izimpondo ze-FPC, izimpondo ze-PCB, izimpondo zasentwasahlobo, izimpondo ze-ceramic patch, i-laser direct structuring (LDS) kanye nezimpondo ze-shrapnel zensimbi.

• Lapho ukhetha i-antenna efanelekile yedivayisi, okokuqala, kuyadingeka ukunquma ukuthi ukhetha i-antenna yangaphakathi noma yangaphandle ngokuya ngesakhiwo somkhiqizo.Uthi lwangaphandle wukufaka uthi ngaphandle kwedivayisi;
• uthi lwangaphandle
• Inzuzo ephezulu;
• Ayithinteki kangako indawo ezungezile, ingasetshenziswa njengomkhiqizo ojwayelekile, futhi yonga imijikelezo yokuthuthukiswa;
• Thatha isikhala futhi uthinte ukubukeka kwemikhiqizo.
• I-antenna eyakhelwe ngaphakathi •
• Inzuzo ephezulu uma kuqhathaniswa;
• Ubuchwepheshe obuvuthiwe nokuvumelana okuhle kokulethwa komkhiqizo;
• Yakhelwe kudivayisi, enhle, asikho isidingo sokwenza izivikelo ezintathu ngokwehlukana;
• Ithintwa kakhulu indawo ezungezile futhi ngokuvamile idinga ukuhlelwa ngokuhambisana nomkhiqizo ngokwawo.
