Uwitekaantenne ya mahembe abiriIrashobora kwanduza no kwakira itambitse ya polarisiyonike kandi ihagaritse polarike ya electromagnetiki yumurongo mugihe itagumije imyanya idahindutse, kuburyo sisitemu yo gutandukanya ikosa rya sisitemu iterwa no guhindura imyanya ya antenne kugirango ihuze ibisabwa byo guhinduranya polarisiyasi ikurwaho, kunoza imikorere ya sisitemu.Antenne ebyiri zifite amahembe abiri afite ibyiza byo kunguka byinshi, kuyobora neza, kwigunga kwinshi, hamwe nubushobozi bunini, kandi byizwe cyane kandi birakoreshwa.Antenne ebyiri zifite polarize irashobora gushyigikira umurongo, elliptique, hamwe nizunguruka ya polarize.
Uburyo bukuru bw'akazi:
Akira Uburyo
• Iyo antenne yakiriye umurongo uhagaritse umurongo uhagaritse, icyerekezo cyonyine gishobora kubyakira, kandi icyambu cya horizontal cyitaruye.
• Iyo antenne yakiriye umurongo wa polarize itambitse ya horizontal, icyambu cya horizontal gusa ni cyo gishobora kuyakira, kandi icyambu gihagaritse.
• Iyo antenne yakiriye imiterere ya elliptique cyangwa izengurutswe na polarize, ibyambu bihagaritse kandi bitambitse byakira ibice bihagaritse kandi bitambitse byerekana ibimenyetso bizengurutse uruziga.Ukurikije ibumoso buzengurutse uruziga (LHCP) cyangwa uruziga rw'iburyo ruzenguruka (RHCP) rw'umuhengeri, hazaba icyiciro cya dogere 90 cyangwa ikiyobora hagati y'ibyambu.Niba umurongo wizuba uzengurutswe neza, ibimenyetso bya amplitude biva ku byambu bizaba bimwe.Ukoresheje ikiraro gikwiye (90 dogere), ibice bihagaritse kandi bitambitse birashobora guhurizwa hamwe kugirango bigarure uruziga cyangwa uruziga.
Uburyo bwo gutangiza
• Iyo antenne igaburiwe kuva ku cyambu gihagaritse, umurongo uhagaritse umurongo uhindagurika.
• Ihererekanya itambitse itambitse neza iyo antenne igaburiwe ku cyambu cya horizontal.
• Iyo antenne igaburiwe na dogere 90 yicyiciro, ibimenyetso bingana na amplitude ku byambu bihagaritse kandi bitambitse, ibyuma bya LHCP cyangwa RHCP byanduzwa bitewe nicyiciro cyatinze cyangwa ikiyobora hagati yibimenyetso byombi.Niba ibimenyetso byerekana amplitude ku byambu byombi bitangana, imiyoboro ya elliptike polarisike yoherejwe.
Uburyo bwo Kwimura
• Iyo antenne ikoreshwa mugukwirakwiza no kwakira uburyo, kubera kwigunga hagati yicyambu gihagaritse kandi gitambitse, kwanduza icyarimwe no kwakirwa birashoboka, nko guhererekanya guhagarikwa no kwakira horizontal muri sisitemu yitumanaho.
