Antenna ebyiri-ihindagurika ihembe irashobora kwanduza no kwakira itambitse ya polarisiyonike kandi ihagaritse ya elegitoroniki ya elegitoroniki ya elegitoroniki mu gihe itagumije imyanya ihagaze, ku buryo ikosa rya sisitemu yo gutandukana ryatewe no guhindura imyanya ya antenne kugira ngo ryuzuze ibisabwa byo guhinduranya polarisation rivaho, kandi kugirango sisitemu ibe ishobora kunozwa. Antenna ya mahembe abiri afite inyungu zo kunguka byinshi, kuyobora neza, kwigunga kwinshi, imbaraga nyinshi, nibindi, kandi yarizwe cyane kandi irakoreshwa. Antenne ebyiri-polarize irashobora gushyigikira umurongo wa polarisiyonike, polarisiyasi ya elliptique hamwe nizunguruka ryizunguruka.
Uburyo bukoreshwa:
| Kwakira Uburyo |
| • Iyo antenne yakiriye umurongo uhagaritse umurongo uhagaritse, icyambu gihagaritse gusa ni cyo gishobora kubyakira, kandi icyambu cya horizontal cyitaruye. mu bwigunge. • Iyo antenne yakiriye imiterere ya elliptique cyangwa izenguruka ya polarisiyasi, ibyambu bihagaritse kandi bitambitse byakira ibice bihagaritse kandi bitambitse byerekana ibimenyetso. Ukurikije uruziga rw'ibumoso ruzenguruka (LHCP) cyangwa uruziga rw'iburyo ruzenguruka (RHCP) rw'umuhengeri, hazaba icyiciro cya dogere 90 gitinda cyangwa kigenda hagati y'ibyambu. Niba umurongo wizuba uzengurutswe neza, ibimenyetso amplitude kuva ku cyambu bizaba bimwe. Ukoresheje (90 dogere) ya Hybrid ihuza, ibice bihagaritse hamwe nibice bitambitse birashobora guhuzwa kugirango bigarure uruziga ruzengurutse cyangwa elliptique. |
| Uburyo bwo kohereza |
| • Iyo antenne igaburiwe nicyambu gihagaritse, itanga umurongo uhagaritse umurongo wa polarisiyasi. • Iyo antenne igaburiwe nicyambu cya horizontal, yohereza umurongo utambitse wa polarisiyasi. • Iyo antenne igaburiwe ku byambu bihagaritse kandi bitambitse ku ntera ya dogere 90 itandukanijwe, ibimenyetso bingana na amplitude, ibimenyetso bya LHCP cyangwa RHCP byanduzwa hakurikijwe icyiciro cyatinze cyangwa kigenda hagati y'ibimenyetso byombi. Niba ibimenyetso amplitude yibyambu byombi bitangana, imiterere ya elliptique polarisiyasi yoherejwe. |
| Uburyo bwo Kwimura |
| • Iyo antenne ikoreshwa muburyo bwo kohereza no kwakira, kubera kwigunga hagati yicyambu gihagaritse kandi gitambitse, irashobora kwanduza no kwakira icyarimwe. |
RF MISOitanga urukurikirane rwibintu bibiri bya antenne ebyiri, imwe ishingiye kumiterere ya quad-ridge indi ishingiye kuri Waveguide Ortho-Mode Transducer (WOMT). Zerekanwa mu gishushanyo cya 1 n’ishusho ya 2.

Isano n'itandukaniro hagati ya antene zombi zerekanwa mu mbonerahamwe ya 1. Muri rusange, antenne ishingiye ku miterere ya quad-ridge irashobora gukwirakwiza umurongo mugari, ubusanzwe urenze umurongo wa octave, nka 1-20GHz na 5-50GHz. Hamwe nubuhanga buhebuje bwo gushushanya hamwe nuburyo bunoze bwo gutunganya,RF MISO'ultra-Broadband dual-polarized antenna irashobora gukora kumurongo mwinshi wa milimetero. Umuyoboro mugari wa antenne ushingiye kuri WOMT ugarukira kubikorwa byogukoresha umurongo wa waveguide, ariko inyungu zayo, ubugari bwumurambararo, lobes kuruhande hamwe na polarisiyasi / kwambukiranya icyambu birashobora kuba byiza. Kugeza ubu ku isoko, antenne ebyiri zifite polarize ebyiri zishingiye kuri WOMT zifite 20% gusa yumurongo mugari kandi ntishobora gupfundika umurongo usanzwe wumurongo wumurongo. WOMT ishingiye kuri antenne ebyiri-polarize yakozwe naRF MISOIrashobora gupfundika umurongo wuzuye wumurongo, cyangwa hejuru ya octave. Hariho moderi nyinshi zo guhitamo.

Antenna ya quad-ridge ibiri-polarize ihembe irakwiriye kubisabwa aho igipimo cyo gupima kigenda cyuzuza imirongo myinshi yumurongo, kandi gifite ibyiza byo kwaguka cyane no kwipimisha byihuse. Kuri antenne ebyiri zifite polarize ishingiye kuri WOMT, urashobora guhitamo ubwoko butandukanye bwa antenne, nk'ihembe rya conical, ihembe rya piramide, gufungura amaherezo ya waveguide probe, ihembe rya lens, ihembe rya scalar, ihembe ryangiritse, ihembe ryibiryo, antenne ya Gaussiya, antenne yisahani, nibindi. Antenna zitandukanye zibereye sisitemu iyariyo yose irashobora kuboneka.RF MISOIrashobora gutanga uruziga kuri urukiramende rwinzibacyuho module kugirango habeho guhuza mu buryo butaziguye hagati ya antenne hamwe n’umuzingi usanzwe uzenguruka hamwe na WOMT hamwe na kare ya kare. WOMT ishingiye kuri dual-polarisation ihembe antenne koRF MISOirashobora gutanga irerekanwa mu mbonerahamwe ya 2.
