Antena ya V ni iki?
Antene ya AV ni antene y'insinga y'icyerekezo igizwe n'ibintu bibiri biyobora amashanyarazi biva hanze uvuye aho umuyoboro uhurira. Iyo urebeye hejuru, amaguru abiri ya antene akora imiterere isobanutse neza isa na V.
Antene ya V ishobora gufatwa nk'uburyo bwiza bwo gutunganya radiateri ebyiri z'insinga ndende. Mu guhitamo uburebure bukwiye bw'ukuguru n'inguni irimo, imirasire ikorwa n'insinga ebyiri ishobora kwiyongera mu byerekezo byatoranijwe, igatanga icyerekezo kinini kurusha antene imwe y'insinga ndende igororotse.
Antene za V zikunze kujyana na sisitemu z'itumanaho zifite umurongo wo hejuru, cyane cyane mu rwego rwa HF. Ariko, umurongo wazo wo gukora ntugenwa n'umugozi uhamye gusa. Imikorere nyayo iterwa n'uburebure bw'amashanyarazi bwa buri kuguru, inguni y'isonga, uburyo bwo kugaburira, uburebure bwo gushyiraho, imiterere y'ubutaka bukikije, ndetse niba impera z'insinga zifunguye cyangwa zirangiye.
Imiterere n'amahame ngenderwaho y'imikorere
Antene isanzwe ya V igizwe n'ibintu bibiri birebire bihujwe n'aho umuyoboro ugana ku gasongero ka V. Imiyoboro yo mu maguru yombi irashyuha mu buryo butandukanye, bivuze ko ifite ubunini bungana kandi ikagira icyerekezo gitandukanye aho umuyoboro ugana.
Buri nsinga ikora imiterere yayo y'imirasire. Iyo imiterere y'antene itoranijwe neza, utwobo tw'imirasire dukorwa n'amaguru yombi turahurirana kandi tugahurira ku murongo wo hagati wa V. Uku kongeramo urwego rw'ubutaka byongera imbaraga z'imirasire mu cyerekezo cyifuzwa kandi kunoza icyerekezo cya antene.
Inguni ebyiri zikunze gukoreshwa mu gusobanura imiterere:
- Inguni iri hagati y'amaguru abiri ya antene ni inguni iriho cyangwa inguni yo hejuru.
- Inguni iri hagati y'ukuguru kumwe n'umurongo wo hagati ni kimwe cya kabiri cy'inguni iri muri yo.
Inguni nziza ntabwo ari agaciro kadahinduka ku isi yose. Irahinduka bitewe n'uburebure bw'amashanyarazi bw'amaguru ya antene n'umuvuduko w'imikorere uteganyijwe.
Imiterere ya antene ya V ifite ibice bibiri by'insinga ndende n'inguni yo hejuru
Antena za V zihumeka kandi zigahagarara
Antene za V muri rusange zishobora kugabanywamo imiterere ibiri.
Antene ya V ifunguye cyangwa ikora resonant igaragaza igice cy'umuraba w'amashanyarazi uturutse ku mpera z'imashini zayo. Utu duce dutanga imiraba ihagaze ku maguru ya antene. Ubusanzwe ubwo bwoko bwa antene butanga imiterere y'imirasire y'icyerekezo cy'ibiri, hamwe n'imirasire ikomeye mu byerekezo bibiri bitandukanye ku ruhande rw'umurongo wa antene.
Antene ya V ihagarara ikoresha imizigo irinda ku mpera z'insinga zombi. Imizigo igabanya urumuri rw'amashanyarazi kandi igafasha gukomeza gukora neza kw'imirasire y'amazi. Ibi bishobora gukumira imirasire mu cyerekezo gishya no gukora imiterere y'umuriro w'amajwi mu cyerekezo kimwe.
Igishushanyo cyarangiye gikunze gutanga icyerekezo gihamye mu buryo burambuye ku rugero rwagutse rw'amajwi, ariko imbaraga zimwe na zimwe za RF zirashira mu byuma bihagarika. Bityo, umuhanga mu gushushanya antene agomba kuringaniza ibisabwa mu gupima umuvuduko w'amajwi, icyerekezo, imikorere myiza, n'uburyo bwo gucunga ingufu.
Ingano y'inshuro n'uburebure bw'amashanyarazi
Antene za V zisanzwe zikoreshwa cyane mu ntera ya HF kuva kuri 3 kugeza kuri 30 MHz kubera ko uburebure bw'umurambararo muri uyu muyoboro butuma insinga zishingiye ku nsinga ziba ingirakamaro mu gushyiraho itumanaho rihamye.
Ariko, antene ya V igenwa n'imiterere yayo n'uburebure bw'amashanyarazi aho kuba igenwa n'intera imwe y'umuvuduko. Buri kuguru gushobora kuba gupima igice cy'uburebure, uburebure bumwe, cyangwa uburebure bwinshi bw'uburebure, bitewe n'imiterere y'imirasire ikenewe n'ubwiyongere bwayo.
Uko uburebure bw'amashanyarazi bw'amaguru bwiyongera, ubuyobozi bwa antene muri rusange bushobora kwiyongera. Muri icyo gihe, hari izindi ngingo zo ku ruhande zishobora kugaragara, kandi imiterere y'imirasire ishobora kwiyongera ku buryo bworoshye bitewe n'inshuro, uburebure bw'aho ishyirwa, uburyo ubutaka butwara amazi, n'uburyo bwo kwihanganira imiterere y'inyubako.
Imiterere n'ubuyobozi bw'imirasire
Imiterere y'imirasire ya antene ya V ikunze kuba ibiri. Imirima ikorwa n'ibice bibiri by'insinga ihurira hamwe igakora utubumbe tunini duhuye n'umurongo wo hagati wa V.
Imiterere y'imirasire ya nyuma igenwa n'ibintu byinshi:
- Uburebure bwa buri kuguru kwa antene
- Inguni iri hagati y'amaguru irimo
- Inshuro zo gukora
- Impedansi n'ibihuzwa by'aho feed-point
- Uburebure bw'inyubako hejuru y'ubutaka
- Ubwinshi bw'insinga n'igihombo cy'umuyoboro w'amashanyarazi
- Igenamiterere rifunguye cyangwa rirangiye
Kongera uburebure bw'ukuguru bishobora gutuma habaho icyerekezo cyo hejuru, ariko bishobora no gutuma impande zikomera. Kubera iyo mpamvu, kwiyongera kwa antene ntibikwiye kwitabwaho hifashishijwe ubugari bw'umurambararo, urwego rw'umurambararo wo ku ruhande, ikigereranyo cy'imbere n'inyuma, hamwe n'imikorere ya impedance.
Imiterere y'imirasire y'icyerekezo cy'ibiri ya antene ya V ihindura icyerekezo
Guhuza uburyo bwo kugaburira no kwirinda ingaruka
Kubera ko antene ya V ubusanzwe ari insinga iringaniye, ikunze gushyirwamo umurongo uhuza amashanyarazi. Iyo hakoreshejwe insinga ya coaxial, hashobora kuba hakenewe balun ikwiye cyangwa umuyoboro uhuye kugira ngo ugabanye umuvuduko uhuza amashanyarazi kuri insinga no kugumana imiterere y’imirasire ingana.
Impedansi y'injira irahinduka bitewe n'uburebure bw'amaguru, inguni yo hejuru, inshuro z'imikorere, uburebure bw'aho ishyirwa, n'imiterere yegereye aho ishyirwa. Guhuza neza impedansi ni ingenzi mu kugabanya imbaraga zigaragara no kugera ku mikorere ihamye ya sisitemu.
Mu guteza imbere antene mu buryo bufatika, injeniyeri zisanzwe zisuzuma igihombo cyo kugaruka, VSWR, imiterere y'imirasire, kwiyongera, polarisation, n'imikorere myiza mbere yo kurangiza imiterere y'antene.
Ibyiza bya Antena za V
Antene ya V itanga ibyiza byinshi bifatika:
- Imiterere yoroshye ishingiye ku nsinga
- Icyerekezo kiri hejuru kurusha ikintu kimwe cy'insinga ndende
- Igiciro gito cyane cyo gukora
- Ikwiriye gushyirwamo HF nini zidahinduka
- Uburebure bw'amaguru buhindagurika n'imiterere y'inguni yo hejuru
- Iboneka mu buryo bw'amajwi n'amashusho y'ingendo
Imbibi z'igishushanyo
Antene za V nazo zifite imbogamizi nyinshi:
- Bisaba umwanya munini wo gushyiramo ibikoresho ku murongo muto.
- Verisiyo za Resonant zishobora gutuma habaho imiraba ikomeye ihagarara.
- Amaguru maremare ya antene ashobora gukora uduce duto two ku ruhande.
- Imikorere ishobora guhinduka cyane bitewe n'inshuro nyinshi.
- Imiterere y'ubutaka n'uburebure bw'aho bushyirwa bishobora kugira ingaruka ku miterere y'imirasire.
- Verisiyo zarangiye zigabanya ubushobozi kuko ingufu zitwarwa n'imizigo.
Porogaramu zisanzwe
Antene za V zakoreshejwe mu buryo busanzwe muri:
- Itumanaho rya radiyo rya HF rikoresha umurongo umwe kugeza ku wundi
- Sitasiyo zo kohereza no kwakira amakuru kuri Shortwave
- Itumanaho rihoraho rikorerwa kure
- Sisitemu zo kugenzura radiyo no kwakira ibimenyetso
- Ubushakashatsi ku itumanaho n'uburezi ku ntene
- Igerageza ry'insinga-antenna rikoresha icyerekezo
- Sisitemu z'itumanaho zihuta n'izikorera mu gace ka kure
Akamaro k'Ubwubatsi
Nubwo sisitemu z'itumanaho zigezweho zikoresha cyane antene nto, antene z'amahoni, antene za interineti, na sisitemu za antene zigenzurwa n'ikoranabuhanga, antene ya V iracyari icyitegererezo cy'ingenzi mu nyigisho za antene.
Bigaragaza neza uburyo uburebure bw'umuyoboro w'amashanyarazi, imiterere y'ubu, imiterere y'antene, n'imiterere y'aho umuyoboro w'amashanyarazi uherereye bigira ingaruka ku iterambere ry'imirasire n'icyerekezo cy'imirasire. Gusobanukirwa iyi mibanire ni ingenzi iyo wiga imiterere ya antene igezweho, harimo antene zipima umurongo mugari, antene zo gupima umuyoboro mugari, antene zo mu buryo bwa microwave, na sisitemu zo gupima antene.
RF MISO ikora ibisubizo bya antene na mikoroonde kugira ngo ikoreshwe mu gupima, gupima, itumanaho, radar, no guhuza sisitemu. Gusobanukirwa neza imiterere y'ingenzi ya antene bifasha injeniyeri guhitamo ibicuruzwa bikwiye no gusuzuma ibipimo by'ingenzi nko kwiyongera, polarisation, beamwidth, impedance, na radiation pattern.
