Antene ifite imiterere ibiri ishobora kohereza no kwakira imiraba ya elegitoroniki ihanamye kandi igororotse mu buryo butambitse mu gihe igumana imiterere y’aho iherereye idahinduka, bityo ikosa ryo kunyura mu myanya ya sisitemu riterwa no guhindura aho antene iherereye kugira ngo huzuzwe ibisabwa byo guhindura imiterere ya polarization rikavaho, kandi kugira ngo uburyo bwo guhindura imiterere ya sisitemu bushobore kunozwa. Antene ifite imiterere ibiri ifite imiterere ibiri ifite ibyiza byo kwiyongera cyane, kuyobora neza, kwitandukanya kwa polarization cyane, ubushobozi bwinshi bw’ingufu, nibindi, kandi yizwe cyane kandi ikoreshwa cyane. Antene ifite imiterere ibiri ishobora gushyigikira imiterere ya polarization iri ku murongo, imiterere ya elliptical na waveforms za polarization zizunguruka.
Uburyo bwo gukora:
| Uburyo bwo Kwakira |
| • Iyo antene yakiriye ishusho y'umuraba ugororotse ugororotse, umurambararo uhagaze ni wo wonyine ushobora kuyakira, kandi umurambararo ugororotse urashyirwa ukwawo. • Iyo antene yakiriye ishusho y'umuraba ugororotse ugororotse, umurambararo ugororotse ni wo wonyine ushobora kuyakira, kandi umurambararo uhagaze urashyirwa ukwawo. • Iyo antene ibonye imiterere y'urumuri rwa polarization ikoze nk'uruziga cyangwa uruziga, imiyoboro ihagaze n'igororotse yakira ibice bihagaze n'ibigororotse by'ikimenyetso, uko bikurikirana. Bitewe n'imiterere y'urumuri rwa polarization ikoze nk'uruziga ibumoso (LHCP) cyangwa imiterere y'urumuri rwa polarization ikoze nk'iburyo (RHCP), hazabaho uburebure bwa dogere 90 cyangwa intambwe hagati y'imiyoboro. Niba imiterere y'urumuri yashyizwe nk'uruziga neza, uburebure bw'ikimenyetso kuva kuri uruziga buzaba bumwe. Hakoreshejwe uburyo bukwiye bwo guhuza (dogere 90), igice gihagaze n'igice gihagaze gishobora guhuzwa kugira ngo hasubizwe imiterere y'urumuri rwa polarization ikoze nk'uruziga cyangwa uruziga. |
| Uburyo bwo kohereza |
| • Iyo antene igejejweho n'aho ihagaze, yohereza umuraba uhagaze ugororotse. • Iyo antene igejejweho n'umuyoboro utambitse, yohereza umuyoboro wa polarization waveform. • Iyo antene igejejwe ku byambu bihagaze n'ibitambitse hakoreshejwe itandukaniro rya dogere 90, ibimenyetso bingana bya amplitude, LHCP cyangwa RHCP waveform yoherezwa hakurikijwe phase iri hagati y'ibimenyetso bibiri. Iyo amplitude ya signal ya zambu ebyiri idahwanye, elliptical polarization waveform yoherezwa. |
| Uburyo bwo Guhindura |
| • Iyo antene ikoreshejwe mu buryo bwo kohereza no kwakira, bitewe n'aho itandukaniye hagati y'aho ihagaze n'aho itambitse, ishobora kohereza no kwakira icyarimwe. |
RF MISOItanga antene ebyiri zifite polarize ebyiri, imwe ishingiye ku miterere ya quad-ridge n'indi ishingiye kuri Waveguide Ortho-Mode Transducer (WOMT). Zigaragara ku Ishusho ya 1 n'Ishusho ya 2.
Ishusho ya 1 Antene y'ihembe ifite polari ebyiri ifite uburebure bune
Ishusho ya 2 Antene ifite polarized horn ebyiri ishingiye kuri WOMT
Isano n'itandukaniro biri hagati y'antene zombi bigaragazwa mu mbonerahamwe ya 1. Muri rusange, antene ishingiye ku miterere ya quad-ridge ishobora gutwikira bandwidth yagutse y'imikorere, akenshi irenze umugozi wa octave, nka 1-20GHz na 5-50GHz. Ifite ubuhanga buhanitse mu gushushanya no gutunganya neza,RF MISOAntene ifite polari ebyiri ya ultra-wideband ishobora gukora ku miyoboro miremire ya milimetero. Umuyoboro w'imikorere wa antene zishingiye kuri WOMT ugengwa n'umuyoboro w'imikorere wa waveguide, ariko kwiyongera kwayo, ubugari bwa beam, lobes zo ku ruhande hamwe na cross polarization/port-to-port isolation bishobora kuba byiza kurushaho. Kuri ubu ku isoko, antene nyinshi zifite polari ebyiri zishingiye kuri WOMT zifite 20% gusa by'umuyoboro w'imikorere kandi ntizishobora gutwikira umuyoboro usanzwe wa waveguide. Antene ifite polari ebyiri ishingiye kuri WOMT yakozwe naRF MISOishobora gutwikira umurongo wose w’amajwi, cyangwa hejuru y’umurongo wa octave. Hari moderi nyinshi zo guhitamo.
