Antena ya Vivaldi: Ihame ry'imikorere, imiterere n'ikoreshwa ryayo

Antene ya Vivaldi, izwi kandi nka antene ifite umuvuduko ukabije, ni antene ifite umurongo wa interineti ukoreshwa cyane muri RF, mikoroonde, radar, intambara y'ikoranabuhanga, gupima no gupima insinga. Umwobo wayo udasanzwe ugabanya umuvuduko wemerera ingufu za electromagnetic guhinduka buhoro buhoro kuva ku buryo bwo kohereza ubutumwa buyobowe ukajya mu mwanya wigenga, bigafasha antene kugera ku mikorere ya interineti n'imirasire y'umurongo.

Ugereranyije na antene nyinshi zikora neza zikozwe neza ku murongo muto w’urukiramende, antene za Vivaldi zikoresha imiterere y’urukiramende. Ibi bituma zikurura cyane sisitemu zisaba ubwinshi bw’urukiramende hamwe n’imiterere yoroshye y’urukiramende cyangwa icyuma.

Antena ya Vivaldi ikora ite?

Antene y'ibanze ya Vivaldi igizwe n'inkombe ebyiri ziyobora amashanyarazi zigize umwanya muto. Uwo mwanya ugenda waguka buhoro buhoro uva mu gace gato k'aho unyura ugana mu mwobo mugari utanga urumuri.

Iyo ingufu za RF zinjiye muri antene, umuraba wa electromagnetic ugenda unyura mu mwanya utose. Uko ubugari bw'umwanya bwiyongera, umuraba uyoborwa ugenda wifatanya mu mwanya utari woroshye kandi unyura cyane cyane mu mpera y'antene.

Uku guhinduka buhoro buhoro ni imwe mu mpamvu zikomeye zituma antene za Vivaldi zishobora gutanga imiterere ya interineti.

Ingano nto y’ikoreshwa iterwa cyane n’ingano y’aho umwobo uherereye n’aho uhagarara, mu gihe imikorere y’inshuro nyinshi iterwa cyane n’ibintu nk’impinduka z’aho umwobo uhagarara, imiterere y’aho uhagarara, ingano y’umuyoboro w’amashanyarazi, n’uburyo ubikora neza.

Ibiranga imirasire

Antene ya Vivaldi muri rusange ni antene ikora ku muriro, bivuze ko imirasire yayo nyamukuru yerekeza ku mpera y'umwobo ufunguye.

Imiterere y'imirasire yayo ishingira ku bipimo byinshi by'imiterere, birimo:

Ubugari bw'umwobo
Uburebure n'imiterere ya Taper
Imiterere y'ibiryo
Inshuro zo gukora
Imiterere y'ubutaka n'imiterere y'umuyoboro w'amazi
Ibipimo bya mekanike

Uko umurongo uhinduka, akarere gatanga urumuri ku miterere yarwo karahinduka. Ibi bituma antene ikora ku rugero rwagutse rw'umurongo utishingikirije ku ijwi rimwe rito.

Antene za Vivaldi zikunze gukoreshwa mu gupima umurongo ugororotse, nubwo imikorere ya polarization iterwa n'imiterere yihariye n'uburyo bwo gutanga.

Ubwoko bw'ingenzi bwa Vivaldi Antena

Imiterere myinshi ya antene za Vivaldi ikunze gukoreshwa mu buhanga bwa RF.

Antena isanzwe ya Vivaldi
Ikoresha umwanya utoroshye wakozwe hagati y'uturere tubiri dutwara amazi kandi ni imwe mu mikoreshereze ikunze gukoreshwa.

Antena ya Vivaldi yo mu bwoko bwa Antipodal
Ikoresha ibintu biyobora amashanyarazi ku mpande zihanganye za substrate ya dielectric. Iyi configuration ishobora gutanga uburyo bworoshye bwo guhindura kuva ku murongo umwe wo kohereza amashanyarazi ujya ku mwobo utanga urumuri.

Antena ya Vivaldi ikoresha uburyo buringaniye
Ikoresha imiterere y’ibice byinshi ingana cyane kugira ngo inoze imiterere y’ubugari bw’aho ukorera n’imiterere y’ubugari muri porogaramu zimwe na zimwe za interineti.

Imiterere itandukanye ishobora gutorwa hakurikijwe uburyo bwo gupima uburebure bw'amakuru (bandwidth), uburyo bwo gupima imiterere y'amakuru (polarisation), uburyo bwo gutanga amakuru (feed), uburyo bwo gukora, n'ibisabwa mu guhuza sisitemu.

Ibipimo by'ingenzi mu gihe uhitamo Antena ya Vivaldi

Mu guhitamo antene ya Vivaldi, umurongo wa frequencies ni wo wo gutangira gusa.

Gain yerekana uburyo antene ishyira imirasire mu cyerekezo cy'imbere neza.

VSWR igaragaza isano iri hagati ya antene na sisitemu ya RF. VSWR iri hasi muri rusange bivuze imbaraga nke zigaragara.

Polarization igomba guhuza na sisitemu ya RF yibanzweho kugira ngo igabanye uburinganire hagati ya polarization.

Ubugari bwa 3 dB busobanura ubugari bw'urukiramende rw'imirasire y'ingenzi kandi ni ingenzi mu gupima radar, gukurikirana, no mu cyerekezo.

Imikorere ya Cross-Polarization nayo ni ingenzi iyo ubuziranenge bwa polarisation ari ngombwa.

Ibintu bya tekiniki nk'ubwoko bw'umuhuza, ingano ya antene, uburemere, imiterere yo gushyiramo, n'uburyo bwo gucunga ingufu nabyo bigomba kwitabwaho mu gihe cyo guhuza sisitemu.

Urugero, Antena ya RF MISO ya RM-VA0212-6 Linear Polarized Vivaldi Antenna ikora kuva kuri 0.2 kugeza kuri 1.2 GHz, itanga 6 dBi isanzwe, ikoresha linear polarization na N-Female interface, kandi ikoreshwa muri radar, itumanaho rya satelite, intambara y'ikoranabuhanga, na porogaramu zo gupima insinga zitagira umugozi.

Ibyiza bya Antena za Vivaldi

Antene za Vivaldi zitanga ibyiza byinshi bifatika:

Umuyoboro munini w'imikorere
Imirasire y'umuriro urangira mu cyerekezo
Imiterere yoroshye cyane irabagirana
Ihuza neza na sisitemu za RF za interineti
Igishushanyo mbonera gishobora kwaguka mu byiciro bitandukanye by'ingufu
Bikwiriye imiterere y'ibintu bimwe na bimwe n'imiterere y'urutonde

Imiterere ya interineti yazo ituma zigira akamaro cyane iyo sisitemu ikeneye gukwirakwira inshuro nyinshi idakoresha antene kenshi.

Porogaramu

Antene za Vivaldi zikunze gukoreshwa muri:

Sisitemu za radar
Intambara y'ikoranabuhanga
Igipimo cya RF cya Broadband
Gupima nta mashini
Gushaka icyerekezo
Gukurikirana ibimenyetso
Gufata amashusho ya mikoroonde
Sisitemu z'itumanaho
Antena zitondetse
Ubushakashatsi n'ikoreshwa rya laboratwari

Muri sisitemu z’imiterere y’amajwi, ibintu byinshi bya Vivaldi bishobora kandi gushyirwa hamwe kugira ngo bibone inyungu nyinshi, imirasire mito, cyangwa ubushobozi bwo kugenzura imirasire y’amashanyarazi.

Umwanzuro

Antene ya Vivaldi ihuza imiterere y’umuraba ugenda uhindagurika, imikorere ya interineti, n’imirasire y’icyerekezo, bigatuma iba imiterere y’antene ikoreshwa mu buryo butandukanye mu bijyanye na RF igezweho na mikoroonde.

Imikorere yayo nyayo iterwa n’imiterere y’urumuri, ingano y’ubuso bw’ingufu, imiterere y’ibiryo, inshuro z’imikorere, n’ishyirwa mu bikorwa rya mekanike. Bityo, abahanga mu by’injeniyeri ntibagomba gusuzuma gusa bandwidth na gain, ahubwo banasuzuma VSWR, polarization, beamwidth, cross-polarisation performance, RF interface, n’ibisabwa mu gushyiraho iyo moderi.

Ku bijyanye na radar, intambara y'ikoranabuhanga, gupima umurongo mugari, itumanaho, no gupima insinga, antene za Vivaldi zitanga igisubizo cyoroshye aho uburyo bwo gupima inshuro nyinshi n'imikorere ya RF mu cyerekezo byombi ari ingenzi.
