Polarization y'uruziga rw'iburyo (RHCP) n'iy'ibumoso (LHCP)Sobanura icyerekezo amashanyarazi azengurukamo uko umuraba wa electromagnetic ukwirakwira. Kumenya neza ni ingenzi mu bijyanye na satelite, radar, gupima antene n'izindi sisitemu za RF kuko antene zohereza n'izakira zigomba gukoresha polarization ijyanye kugira ngo zigere ku ihererekanya ry'amashanyarazi rinoze.
Iyi mfashanyigisho isobanura uburyo bwo kureba, itegeko rikoreshwa mu gukoresha ukuboko, isano iri hagati y’ibice by’umurima n’ibice, igipimo cy’umurongo n’ibipimo by’ingenzi bigomba kugenzurwa mu gihe uhitamo antene ifite uruziga.
Ingero za RF MISO MISO Circularly Polarized Horn Antena
RF MISO itanga moderi za antene z’ihembe zizunguruka ku migozi ikoreshwa yatoranijwe. Ingero zikurikira zigaragaza amahitamo atandukanye y’intera y’imperekeza; buri gihe yemeza uburyo bwo gukoresha intoki, ikigereranyo cy’umurongo, inyungu, aho zihurira n’amakuru ya mekanike mu rupapuro rw’amakuru rw’icyitegererezo kiri ubu mbere yo guhitamo.
RM-CPHA82124-20Antene y'ihembe ifite uruziga ya 8.2–12.4 GHz
RM-CPHA1840-12Antene y'ihembe ifite uburebure bwa 18–40 GHz
RM-CPHA218-16Antene y'ihembe ry'uruziga rya 2–18 GHz
Suzuma icyiciro cyose: Antene za RF MISO zizunguruka zikora polarization horn, harimo RHCP, LHCP n'amahitamo ya polarization y'uruziga rubiri hakurikijwe icyitegererezo.
Polarization y'uruziga ni iki?
Polarization isobanura inzira ikurikiranwa na vector y'amashanyarazi ahantu hadahinduka mu kirere. Muri polarization y'umurongo, vector iguma ku murongo ugororotse. Muri polarization izengurutse neza, ubunini bwayo ntibuhinduka mu gihe vector izenguruka muri dogere 360 muri buri ruziga rwa RF. Antene zikora ubusanzwe zikora inzira isa n'uruziga, bityo uruziga rupimwa naigipimo cy'umurongo ugororotseUmuraba mwiza uzunguruka ufite igipimo cy’uruziga cya 0 dB; igipimo cy’uruziga gito gipimwe kigaragaza ubwiyongere bw’uruziga hafi y’uruziga.
Polarization y’uruziga ishobora gukorwa n’ibice bibiri by’umurongo ugororotse bifite amplitude ingana n’itandukaniro ry’icyiciro cya dogere 90 cyangwa plus cyangwa minus. Ikimenyetso cy’iyo sano y’icyiciro cya quadrature kigaragaza niba umuraba ari RHCP cyangwa LHCP hakurikijwe amategeko yavuzwe.
RHCP vs LHCP: Vuga amasezerano yo kureba
Ubuhanga bushobora kugaragara nk'aho buhindutse iyo umurima umwe uzenguruka urebewe mu byerekezo bitandukanye. Kugira ngo wirinde ko ibintu bitagenda neza, vuga icyerekezo cyo kureba. Dukurikije amategeko asanzwe akoreshwa muri IEEE, ubuhanga busobanurwa mu gihe urebamu cyerekezo cyo gukwirakwiza umuraba, uhereye aho urugendo ruherereye ugana mu cyerekezo cy'urugendo.
Uburyo bufatika ni ukugaragaza igikumwe cyawe mu cyerekezo cyo gukwirakwiza. Niba izunguruka ry'amashanyarazi rikurikira intoki ziri ku kuboko kwawe kw'iburyo, umuraba ni RHCP muri ubu buryo; niba ukurikira ibumoso, ni LHCP. Kubera ko inyandiko zimwe na zimwe n'amasomo amwe bikoresha uburyo butandukanye bwo kureba, emeza uburyo bukoreshwa mu ipaji y'amakuru ya antene hanyuma ugerageze mbere yo kugereranya ibisubizo.
Ibice bigize ikigo n'isano y'icyiciro
Tekereza ku bice bibiri by'umuraba w'indege bigenda ku murongo wa z. Igice kimwe cy'amashanyarazi gishingiye kuri x hamwe na amplitude Ex; iya kabiri ijyanye na y hamwe n'ubugari bwa Ey. Ingano yabo ya vector igena imiterere ya polarisation ikomokaho.
Iyo hari igice kimwe gusa, umuraba ushyirwa ku murongo ugororotse kuri uwo murongo. Iyo ibice byombi bihari, uburebure bwabyo n'icyiciro byabyo bigena niba igisubizo ari umurongo ugororotse, uruziga cyangwa uruziga.
Isano iri hagati y’ibice byombi ishobora gusobanurwa muri make ku buryo bukurikira:
- Niba Exni nonzero na Eyni zeru, polarisation ni umurongo ugororotse ukurikije x.
- Niba Eyni nonzero na Exni zeru, polarisation ni umurongo ugororotse ukurikije y.
- Iyo ibice byombi biri mu cyiciro, umubare wabyo wa vector ukomeza kuba umurongo ugororotse ku nguni idahinduka.
- Iyo ibice bifite amplitude ingana n'itandukaniro ry'icyiciro cya dogere 90 cyangwa plus, igisubizo ni polarisation nziza y'uruziga.
Iyo ibice bya orthogonal bitangana, cyangwa itandukaniro ry'icyiciro ritari dogere 90 neza, umurima ukurikirana ellipse aho kuba uruziga. Niyo mpamvu urupapuro rw'amakuru rwa antene rugomba kugaragaza ikigereranyo cy'umurongo ugororotse ukurikije inshuro, kandi aho bikenewe, ukagaragaza ubwinshi bw'inguni buteganyijwe. Ubuhanga bwonyine ntibusobanura ubwiza bwa polarization.
Impamvu guhuza imiterere y'impande zombi ari ingenzi
Antene yakira ikuramo imbaraga nyinshi ziboneka iyo polarisation yayo ihuye n'umuraba winjira. Imiterere ya polarisation inyuranye n'uruziga irahuza, bityo kudahuza kwa RHCP na LHCP bishobora guteza igihombo gikomeye cya polarisation. Antene nyazo zitanga kwangwa kwa cross-polarisation, kandi imikorere ipimwa iterwa n'ikigereranyo cy'umurongo, imiterere, reflections n'ibidukikije bikikije ikizamini.
Umucyo uturuka ku buso buyobora ibintu ushobora guhindura imiterere y’urusobe rw’amashanyarazi, kandi radomes, ibikoresho cyangwa imiterere yegereye bishobora guhindura urwego rw’amashanyarazi. Kugira ngo ugenzure neza, shyira antene zombi kuri boresight, koresha uburyo buzwi bwo gusuzuma amashanyarazi, gereranya imbaraga zakiriwe kuri RHCP na LHCP, kandi upime ikigereranyo cy’umurongo n’imikorere ya cross-polarisation mu gice gikenewe.
Uburyo bwo guhitamo Antena ya RHCP cyangwa LHCP
Mbere yo guhitamo antene ifite uruziga, sobanura ibisabwa byose mu mikorere aho guhitamo ukurikije inshuro gusa:
- Ingano y'inshuro:emeza ko itumanaho ryose rikwirakwizwa, atari gusa hagati.
- Polarization:garagaza RHCP, LHCP cyangwa polarization y’uruziga rubiri hamwe n’uburyo bwo guhanagura.
- Igipimo cy'imirongo:genzura umupaka usabwa mu gihe cy'inshuro n'igihe cy'ingufu.
- Inyungu n'ubugari bw'umurambararo:Ingengo y'imari y'aho ibintu bihurira, uburyo bwo kubigeraho n'ibikenewe mu gupima intera.
- Guhuza impedance:Suzuma VSWR cyangwa ugaruze igihombo ukoresheje umugozi wose.
- Interineti ya RF n'imbaraga:kugenzura uburyo bwo guhuza cyangwa gukwirakwiza umuyoboro w'amashanyarazi n'ibikenewe mu gucunga ingufu.
- Guhuza imikorere ya tekiniki:emeza ibahasha, aho gushyiramo, aho icyerekezo giherereye n'ibisabwa mu bidukikije.
Vugana n'inzobere mu bijyanye na RF MISO Antena
RF MISO ni uruganda rukora antene za RF na mikoroonde. Sangiza ingano y'ingufu zawe, ubushobozi bwo gukoresha, inyungu, ikigereranyo cy'umurongo, aho uhurira n'aho ushyiramo kugira ngo itsinda ryacu rishobore kugufasha kumenya icyitegererezo gikwiye cyangwa kuganira ku bisabwa mu gukoresha porogaramu.
