Igisubizo cyihuse:Antene ya log periodic ni antene y’umurongo uhuza umurongo wa interineti yakozwe mu ruhererekane rw’ibintu bipima imirasire. Amatsinda atandukanye y’ibintu akoresha amashanyarazi ku murongo utandukanye, bigatuma antene imwe igumana impedance y’ingirakamaro n’imiterere y’imirasire mu gice kinini cy’imikorere. Antene za log periodic zikoreshwa cyane mu gupima EMI/EMC, kugenzura spectrum, gupima antene, gushaka icyerekezo na sisitemu ya RF ya interineti.
Antena y'igihe gito ya Log ni iki?
A antene y'igihe runaka, akenshi isobanurwa nka LPA, ni umuryango wa antene udakoresha frequency aho imiterere yawo ihinduka mu buryo busubiramo bwa logarithmic. Uburyo bukunze gukoreshwa cyane ni log periodic dipole array (LPDA), ikoresha ibintu bya dipole by'uburebure butandukanye n'intera zitandukanye ku buryo bugenda butandukana ku gitereko gishyigikira.
Bitandukanye na antene y'umugozi muto yakozwe ku burebure bumwe bunini bw'umuvuduko, LPDA ikoresha ibintu byinshi bifite uburebure kugira ngo itwikire imirongo ya frequencies yatoranijwe. Ku nshuro iyo ari yo yose ikora, itsinda ry'ibintu hafi ya resonance gusa ni ryo ritanga cyane imirasire. Aka gace kitwaakarere gakoraUko inshuro zihinduka, akarere gakora kagenda gakurikira urutonde.
Antena y'igihe gito ikora ite?
Ingano z'ibintu byegeranye zifitanye isano n'igipimo cy'umunzani, gikunze kugaragazwa n'inyuguti y'Ikigiriki tau. Uburebure bw'ibintu, intera n'ibindi bipimo bikurikirana ubu buryo bungana. Kubera ko imiterere isubiramo mu buryo bw'amashanyarazi iyo frequency ihindutse ku gipimo kimwe, impedance y'injira n'imyitwarire y'imirasire bishobora kuguma bihamye ugereranyije n'umurongo mugari.
Ibintu birebire cyane bishyigikira igice cy’umuvuduko wo hasi w’urwego rw’imikorere, mu gihe ibintu bigufi bishyigikira igice cy’umuvuduko wo hejuru. Ingufu zinyuzwa mu buryo bungana bwo gutanga, kandi isano iri hagati y’ibintu byegeranye ikora icyerekezo. Inyungu nyayo, ubugari bw’umuvuduko, igipimo cy’imbere n’inyuma hamwe n’impinduka biterwa n’imiterere irambuye, imiterere y’inkunga, ibidukikije byo gutanga n’aho bishyirwa.
Ibiranga Imikorere y'ingenzi
- Umuyoboro mugari w'imikorere:Icyitegererezo kimwe gishobora gutwikira umugozi mugari kurusha dipole isanzwe ya resonant, bigabanya gukenera guhindura antene mu gihe cyo gupima frequency ya sweep-frequency.
- Imirasire y'icyerekezo:Umurabyo w'ingenzi ufasha kunoza uburyo bwo guhitamo ahantu hagenewe gukurikirana, gupima no gushaka icyerekezo.
- Imyitwarire ihamye:urutonde rwakozwe neza rushobora gutanga umusaruro mwiza w’inyungu n’imikorere ya impedance mu gice cyarwo cyagenwe, nubwo buri gipimo kigomba kugenzurwa ku rupapuro rw’amakuru rwa buri wese.
- Polarization y'umurongo cyangwa ibiri:Polarization ishingiye ku buryo bw'icyitegererezo. Imiterere ifite polarize ebyiri ishobora gushyigikira polarize ebyiri zigororotse mu itsinda rimwe rya antene.
- Itandukaniro ry'ingano n'inshuro:Uburyo bwo gupima ibintu mu buryo bworoshye busaba ibintu birebire n'imiterere minini ya mekanike. Ahantu ho gushyira ibintu, imitwaro y'umuyaga n'intera yo kugerageza ni ingenzi mu gihe cyo guhitamo.
Porogaramu zisanzwe
- Isuzuma rya EMI na EMC:Ibipimo by'ubudahangarwa bw'amashanyarazi n'uburinzi bw'umubiri mu byiciro byatoranijwe.
- Igipimo cya antena:kugereranya inyungu, gupima imirasire n'ibikorwa byo gupima umurongo mugari.
- Gukurikirana imiterere y'amatara:kwakira ibimenyetso ku mirongo myinshi ya frequence nta gusimbuza antene kenshi.
- Gushaka icyerekezo no kugenzura:Igisubizo cy’icyerekezo gishyigikira isesengura ry’ibimenyetso iyo gishyizwe muri sisitemu ya RF ikwiye.
- Ubushakashatsi ku bijyanye n'ikoranabuhanga ridafite umugozi (wireless) na RF:kohereza cyangwa kwakira ibintu muri rusange mu buryo bwo gupima muri laboratwari no mu murima.
Uburyo bwo Guhitamo Antena y'Icyiciro cya logi
Tangira ukoresheje uburyo bwose bwo gupima cyangwa ibisabwa muri sisitemu aho gukoresha ingano y'inshuro gusa. Ingingo zikurikira zifasha abahanga mu by'imashini n'abaguzi kugereranya moderi:
| Ikintu cyo guhitamo | Impamvu ari ingenzi |

| Polarization | Hitamo polarisation y'umurongo cyangwa ibiri hakurikijwe isoko, igipimo cy'igerageza n'uburyo bwo gupima. |
| Umuhuza n'ingufu | Emeza ko ihuye na sisitemu y'insinga hamwe n'urwego rw'ingufu ruhoraho cyangwa rurerure rukenewe. |
| Ibahasha ya tekiniki | Suzuma ingano, uburyo bwo gushyiraho no gushyiramo ibikoresho, cyane cyane ku bikoresho bifite umurongo muto. |
Icyo wabaza uwakoze Antena y'igihe gito ya Log
Iyo ugereranijeuruganda cyangwa utanga antene zikora igihe runaka, saba urupapuro rw'amakuru rugezweho rw'icyitegererezo kandi wemeze uburyo inyungu, VSWR, imirasire na polarization byashyizwe ku rutonde bikoreshwa mu gice cyose cy'umuyoboro. Ibishushanyo bya mekanike, icyerekezo cy'umuyoboro n'ibisobanuro byo gushyiraho nabyo ni ingenzi kuko antene ya interineti ishobora kuba ikwiriye amashanyarazi ariko ikaba idakora neza ku cyumba runaka, inkingi cyangwa imiterere y'ubutaka.
RF MISO ikora, ikanatanga antene za RF na mikorobe kugira ngo zipimwe, zigenzurwe kandi zihuzwe na sisitemu.

Ibibazo Bikunze Kubazwa
Ni irihe tandukaniro riri hagati ya antene ya log periodic na antene ya Yagi?
Antene ya Yagi ubusanzwe ikoreshwa neza ku mugozi muto kandi ikoresha ikintu kimwe gikoresha umugozi gifite imiterere ya parasite na reflector. Urwego rwa dipole rukoresha ibintu byinshi bipima kandi bikoresha umugozi kandi rwagenewe gukoreshwa mu muyoboro wa interineti. Guhitamo neza biterwa n'ibisabwa ku mugozi, inyungu, ingano n'ibipimo.
Ese antene ya log periodic irashobora gukoreshwa haba mu kohereza no kwakira?
Yego, iyo moderi yatoranijwe, connector n'ingufu byujuje ibisabwa muri sisitemu. Emeza agaciro k'ingufu gahoraho kandi gakomeye mu rupapuro rw'amakuru ruheruka mbere yo kohereza.
Ese buri antene ya log periodic ikora frequency imwe?
Oya. Buri moderi ifite umugozi wayo, inyungu, VSWR, polarisation n'ingano za mekanike. Uruhererekane rwa RF MISO rutanga moderi zikubiyemo imigozi yatoranijwe, bityo injeniyeri zigomba kugereranya ibisobanuro byose aho guhitamo ubwoko bwa antene gusa.
Ganira ku byo Antena Yawe Ikeneye
Ohereza RF MISO umurongo wawe w'imikorere n'ibisabwa mu igerageza cyangwa sisitemu kugira ngo ubone ubufasha mu guhitamo icyitegererezo.
