Ungakhetha kanjani i-antenna yethu efanelekile!

1. Ukukhethwa kwezinti zangaphandle

Okokuqala, kuyadingeka ukunquma indawo yokumboza isignali yedivayisi.Ukuqondisa kwesiginali kunqunywa iphethini yemisebe ye-antenna.Ngokuya ngokuqondiswa kwemisebe ye-antenna, i-antenna ihlukaniswe yaba i-omnidirectional antenna kanye ne-directional antenna.

I-Antenna Yangaphandle Nge-Magnetism

Inzuzo iphakeme uma kuqhathaniswa, futhi isici esikhulu kunazo zonke ukuthi inkomishi enamandla kazibuthe yokumunca, elula kakhulu ukuyifaka nokuyilungisa, kodwa inkomishi yokumunca kufanele ikhangiswe endaweni yensimbi.Embonini yemojula engenantambo, uthi lwenkomishi yokumunca ivamise ukusetshenziswa ngokuhambisana nemojula engenantambo ukuze kwandiswe imojula engenantambo.Inhloso yebanga lokuxhumana, njengokufunda imitha ehlakaniphile, imishini yokuthengisa, amakhabethe e-express, imisakazo yemoto, njll.

Ngokufanayo nothi oluvamile lokumunca inkomishi emise okwesiswebhu, kodwa okuhle ngaphezu kwenkomishi yokumunca emise okwesiswebhu ukuthi ukusetshenziswa kwerediyetha yethusi emsulwa enobubanzi obukhulu kunokulahlekelwa kwe-ohmic okuphansi, ukusebenza kahle kwezimpondo eziphakeme kanye nokumbozwa komkhawulokudonsa obanzi.Ifanele iziteshi zokudlulisa idatha ezinezidingo zokusebenza eziphakeme uma kuqhathaniswa, kanye nokudluliswa kwesithombe ebangeni elimaphakathi.

I-Antenna yerabha

I-antenna yangaphandle evamile kakhulu, enenzuzo emaphakathi kanye nenani eliphansi uma kuqhathaniswa, ivame ukusetshenziswa kumamojula okuxhumana angenantambo, amarutha angenantambo, imisakazo yedijithali, njll. I-antenna enosayizi ofanele ingakhethwa ngokuvumelana nezidingo zesikhala sokufakwa.Ukukhethwa kosayizi we-antenna kuhlobene nenzuzo.Ngokuvamile, uma ubude bebhendi yefrikhwensi bude, buyanda inzuzo.

I-antenna ye-Fiberglass

Phakathi kwama-omnidirectional antenna, i-antenna ye-FRP inokusebenza okuhle kakhulu.Ingaphakathi layo elingaphakathi liyi-vibrator yethusi elihlanzekile, futhi lithatha ukudla okunokulinganisela futhi alithinteki kangako endaweni ezungezile.kuhle.Ifaneleka kakhulu ukumbozwa kwesiginali yesango lebanga elide, ukudluliswa kwesithombe, njll.

i-antenna yephaneli eyisicaba

Ukusebenza kahle okuphezulu, ukukhanya nosayizi omncane, kulula ukuyifaka, kungacabangela inzuzo kanye nendawo yemisebe.Ilungele ukumbozwa kwesignali engenantambo yangaphakathi kanye nomhubhe;ukudluliswa kwesignali yebanga eliphakathi, ukudluliswa kwesithombe kanye nokungena kwesignali ngezindonga, njll.

I-Antenna ye-Yagi

Inzuzo iphezulu kakhulu, ivolumu inkulu kancane, isiqondiso sinamandla, futhi isiqondiso se-antenna sidinga ukunakwa lapho sisisebenzisa.Ingasetshenziselwa ukudlulisa isignali yebanga elide, ukudluliswa kwesithombe nokuthola isiqondiso.

Faka i-antenna ngezikhathi ezithile

I-antenna ebanzi kakhulu enomkhawulokudonsa obanzi kakhulu, ofinyelela ku-10:1 umkhawulokudonsa, ovame ukusetshenziselwa ukukhulisa isignali, ukusatshalaliswa kwasendlini kanye nokumbozwa kwesiginali yekheshi.

2.Ukukhethwa kothi olwakhelwe ngaphakathi

Ifomu le-Antenna Eshumekiwe lingahlukaniswa libe: I-FPC/PCB/spring/ceramic/hardware shrapnel/laser direct structuring (LDS) nezinye izinhlobo.Njengamanje, izinti ze-FPC ne-PCB zivame ukukhethwa;endabeni yokulawulwa kwezindleko eziphezulu kanye nezidingo zokusebenza ezijwayelekile, iziphethu eziningi nama-shrapnel ensimbi akhethiwe;ngezimo zesicelo esikhethekile, i-ceramic patch noma izimpondo ze-LDS zikhethwa, futhi izimpondo ezijwayelekile ezakhelwe ngaphakathi zithintwa imvelo.umthelela, udinga umklamo wangokwezifiso noma ukufanisa okuvimbile.

I-FPC

Inenani elihle/isilinganiso sokusebenza futhi ingafaniswa nemibala ehlukahlukene yokubukeka ngemva kokujova uphethiloli;umkhiqizo unokuguquguquka okuhle futhi ungafakwa ngokuphelele endaweni evamile ye-arc;inqubo ivuthiwe futhi izinzile, umjikelezo wokukhiqiza uyashesha, futhi ukulethwa kwenqwaba kuhle;ifanele ukusebenza kabi.Idizayini ye-antenna yedivayisi ehlakaniphile efunwa kakhulu.

PCB

Umehluko omkhulu phakathi kwe-PCB antenna kanye ne-FPC antenna ukuthi i-FPC inokuguquguquka okuhle, kanti uthi lwe-PCB ibhodi eliqinile.Ekufakweni kwesakhiwo, uma udinga ukugoba kanye ne-arc, khetha uthi lwe-FPC.Uma kuyindiza, ungakhetha uthi lwe-PCB.I-FPC kulula ukuyifaka.

i-antenna yasentwasahlobo

Isici sayo esikhulu kunazo zonke ukuthi ishibhile, kodwa sinenzuzo ephansi kanye nomkhawulokudonsa omncane;uma yakhelwe emkhiqizweni, kuvame ukudingekile ukulungisa iphutha lokumatanisa kwe-antenna.

I-Ceramic Patch Antenna

Izinyathelo ezincane, ukusebenza kahle;umkhawulokudonsa omncane, kunzima ukufeza i-multi-band;ngcono ngempumelelo ukuhlanganiswa kwebhodi eliyinhloko, futhi kunganciphisa imingcele ku-ID ye-antenna;Umklamo udinga ukungeniswa ekuqaleni kwencazelo yebhodi.

I-antenna ye-Metal shrapnel

Inokusebenza kwezindleko eziphezulu futhi inganciphisa ngempumelelo izindleko;umkhiqizo unamandla aphezulu futhi akulula ukonakala;inqubo ivuthiwe futhi izinzile, umjikelezo wokukhiqiza uyashesha, futhi ukulethwa kwenqwaba kuhle;uhlelo lokusebenza endaweni ye-antenna kanye nendawo ye-arc kunemikhawulo ethile.
