A Antena y'ihembe ry'uruzigani ubwoko bwihariye bwa antene ya mikoroonde yagenewe gutangaza cyangwa kwakira imiraba ya electromagnetic hamwe na polarisation y'uruziga. Bitandukanye na polarisation y'umurongo, aho ingufu z'amashanyarazi zizunguruka mu murongo umwe, polarisation y'uruziga ifite vector y'amashanyarazi izenguruka buri gihe uko umuraba ugenda ukwirakwira, ikurikirana imiterere ya helical. Iyi miterere idasanzwe itanga inyungu zikomeye mu buryo butandukanye bugoye bwo gutumanaho no kumva.
Ibyiza by'ingenzi byo gutandukanya ikirere n'urukiramende
1. Ubudahangarwa ku miterere idahwitse y'ubwiyongere bw'impande
Muri sisitemu ya polarization igororotse, antene zo kohereza ubutumwa n'izo kwakira zigomba kuba zigororotse mu miterere yazo ya polarization kugira ngo hirindwe gutakaza ikimenyetso. Polarization izenguruka ikuraho iki gisabwa. Umuraba wa polarized uzunguruka ugumana imbaraga zihoraho z'ibimenyetso hatitawe ku cyerekezo cya antene yakira—akamaro gakomeye ku itumanaho rya satelite igendanwa, aho ingendo z'ikinyabiziga zihora zihindura imiterere ya antene.
2. Kugabanya ikibazo cyo kubangamira inzira nyinshi
Iyo umuraba uzunguruka ugaragara hejuru y'ikintu (nk'amazi, inyubako, cyangwa ubutaka), ukuboko kwawo guhindagurika kurahinduka (urugero, ukuboko kw'iburyo guhinduka ibumoso). Antene zakira intoki zagenewe ukuboko kumwe zihakana ukuboko gutandukanye, bigasiba ibimenyetso byagaragaye bituma inzira nyinshi zishira. Iyi miterere ni ingenzi cyane mu kwakira GPS no mu miyoboro y'itumanaho mu mijyi.
3. Kwinjira binyuze mu ngaruka z'ikirere
Polarization y’uruziga igaragaza ubudahangarwa bukomeye ku kuzunguruka kwa Faraday—ikintu aho imbaraga rukuruzi z’Isi zizunguruka urwego rwa polarization rw’imiraba ya polarized inyura muri iyonosphere. Mu gukuraho uburyo bwo kumva ko polarization izunguruka, polarization y’uruziga ituma ibimenyetso biramba mu miyoboro ya satelite ijya ku butaka ndetse n’itumanaho ry’ikirere cyimbitse.
4. Imikorere myiza mu bihe bibi
Imvura, igihu n'urubura bituma imiraba yazungurutse igabanuka ugereranije na polarisation igororotse ku miyoboro imwe n'imwe, bigatuma polarisation izunguruka iba amahitamo meza kuri sisitemu za radar n'imiyoboro y'itumanaho ikorera mu turere dufite imvura nyinshi.
Ishyirwa mu bikorwa rya Antena y'Amahembe
Polarization y’uruziga muri antene z’ihoni ikunze kugerwaho binyuze muri polarizers zivanze—imiterere ya mekanike nka dielectric slabs, corrugations, cyangwa septum polarizers zishyirwa mu ifunguro rya waveguide. Ibi bice bihindura ubwinjiriro bwa linearly polarized mo uruziga rwa polirized hamwe n’ubuziranenge bwinshi n’igihombo gito cyo kwinjiramo.
Porogaramu Zisanzwe
•Itumanaho rya Satellite: Ibikoresho byo hasi na antene zo mu kirere byishingikiriza kuri polarization y'uruziga kugira ngo bigumane ubusugire bw'aho uruziga ruhagaze nubwo hari ingendo za satelite n'ingaruka z'ikirere.
•Sisitemu za Satellite zo Kugenda ku Isi (GNSS): Ibimenyetso bya GPS, BeiDou, na Galileo bikoresha polarization y'uruziga kugira ngo bigenzure ahantu hizewe mu mikokwe yo mu mijyi no mu bidukikije bifite inzira nyinshi.
•Sisitemu za Radar: Radar y'ikirere na radar ikurikirana intego yungukira ku bushobozi bwa circular polarization bwo gutandukanya akajagari k'imvura n'intego nyazo.
•Intambara n'Ubutasi by'ikoranabuhanga: Polarization izunguruka ituma ubushobozi bwo gufata ibimenyetso bukomera hatitawe ku miterere ya polarization y'ikimenyetso.
•RFID & Wireless Power Transfer: Ituma habaho itumanaho rihoraho hamwe na tagi mu buryo butunguranye.
Antene z'urukiramende zizunguruka zigaragaza ikoranabuhanga rikuze ariko rihora ritera imbere, ritanga imbaraga zitagereranywa mu buryo bufatika bwo gukwirakwiza ibintu mu isi.RFMiso, duhuza ubuhanga bwo gukora neza n'uburyo bwo kugenzura imiterere y'ikirere kugira ngo dutange ibisubizo bigezweho bihuye n'ibikorwa bigoye cyane mu by'indege, mu by'umutekano, no mu itumanaho.
