Muri tekinoroji yo gutumanaho idafite umugozi, gusa isano iri hagati yigikoresho cya transceiver idafite na antenne ya sisitemu ya RFID niyo idasanzwe. Mu muryango wa RFID, antene na RFID ni abanyamuryango bakomeye. RFID na antene biraterana kandi ntibishobora gutandukana. Yaba umusomyi wa RFID cyangwa tagi ya RFID, yaba tekinoroji ya RFID yumurongo mwinshi cyangwa tekinoroji ya ultra-high-frequency RFID, ntaho itandukaniye naantenna.
RFIDantennani ihindura ihindura imiyoboro ikwirakwizwa kumurongo wohereza mumashanyarazi ya electronique ikwirakwiza muburyo butagira umupaka (ubusanzwe umwanya wubusa), cyangwa ubundi. Antenne ni igice cyibikoresho bya radio bikoreshwa mu kohereza cyangwa kwakira imiraba ya electroniki. Imbaraga za radiyo yumurongo wa radiyo yoherejwe na radiyo yoherezwa muri antenne binyuze muri federasiyo (umugozi), kandi ikwirakwizwa na antenne muburyo bwa electronique. Nyuma yumurongo wa electromagnetiki ugeze aho wakiriye, wakirwa na antene (igice gito cyingufu zirakirwa) hanyuma woherezwa kumaradiyo ukoresheje federasiyo, nkuko bigaragara mumashusho hepfo.
Ihame ryo gukwirakwiza imirasire ya electromagnetic kuva kuri antene ya RFID
Iyo insinga itwaye insimburangingo, irasa imirasire ya electromagnetique, kandi ubushobozi bwayo bwimirasire ijyanye n'uburebure n'imiterere y'insinga. Niba intera iri hagati yinsinga zombi yegeranye cyane, umurima wamashanyarazi uboshye hagati yinsinga zombi, bityo imirasire iba idakomeye; iyo insinga zombi zimaze gukwirakwira, umurima w'amashanyarazi ukwirakwizwa mumwanya ukikije, bityo imirasire ikiyongera. Iyo uburebure bwinsinga ari buto cyane kurenza uburebure bwumuraba wa electromagnetic yumuriro, imirasire iba idakomeye; iyo uburebure bwinsinga bugereranwa nuburebure bwumuraba wumuriro wa electromagnetic yumuriro, umuyoboro winsinga wiyongera cyane, ugakora imirasire ikomeye. Umugozi ugororotse wavuzwe haruguru ushobora kubyara imirasire ikomeye mubisanzwe witwa oscillator, naho oscillator ni antenne yoroshye.
Uburebure burebure bwa electromagnetic waves, nini nini ya antenne. Imbaraga nyinshi zigomba gukwirakwizwa, nini nini ya antenne.
RFID antenna yubuyobozi
Imirasire ya electromagnetique irasa na antenne irayobora. Ku ihererekanyabubasha rya antene, icyerekezo cyerekeza ku bushobozi bwa antenne bwo gukwirakwiza imiraba ya electronique mu cyerekezo runaka. Kubakira byanyuma, bivuze ubushobozi bwa antenne yo kwakira amashanyarazi yumurongo uturutse mubyerekezo bitandukanye. Igishushanyo cyibikorwa hagati yimirasire ya antenne hamwe nu murongo uhuza umwanya ni antenne. Gusesengura imiterere ya antenne irashobora gusesengura ibiranga imirasire ya antenne, ni ukuvuga ubushobozi bwa antenne bwo kohereza (cyangwa kwakira) imiraba ya electroniki ya magnetiki mubyerekezo byose mumwanya. Ubuyobozi bwa antenne busanzwe bugereranwa nu murongo ku ndege ihagaritse hamwe nindege itambitse igereranya imbaraga zumuriro wa electromagnetique irasa (cyangwa yakiriwe) mubyerekezo bitandukanye.
Mugukora impinduka zijyanye nimiterere yimbere ya antenne, icyerekezo cya antenne kirashobora guhinduka, bityo bigakora ubwoko butandukanye bwa antene ifite imiterere itandukanye.
RFID antenna yunguka
Antenna yunguka isobanura muburyo urwego antenne ikwirakwiza imbaraga zinjiza muburyo bwibanze. Urebye ku buryo bw'icyitegererezo, bigenda bigabanuka lobe nyamukuru, ntoya kuruhande, kandi inyungu nyinshi. Muri injeniyeri, inyungu ya antenne ikoreshwa mugupima ubushobozi bwa antenne yo kohereza no kwakira ibimenyetso mubyerekezo runaka. Kongera inyungu birashobora kongera ubwishingizi bwurusobe muburyo runaka, cyangwa kongera inyungu murwego runaka. Mubihe bimwe, uko inyungu ziyongera, niko radiyo ikwirakwira.
Gutondekanya antene ya RFID
Antenna ya Dipole: Nanone yitwa antenne ya dipole ya simmetrike, igizwe ninsinga ebyiri zigororotse zuburebure bumwe nuburebure butondekanye kumurongo ugororotse. Ikimenyetso kigaburirwa uhereye kumpera zombi hagati, kandi kugabura kugihe bizakorwa kumaboko yombi ya dipole. Ikwirakwizwa ryubu rizashimisha umurima wa electromagnetic mumwanya ukikije antene.
Antenna ya Coil: Nimwe muri antene ikoreshwa cyane muri sisitemu ya RFID. Mubisanzwe bikozwe mu nsinga zikomeretsa uruziga cyangwa urukiramende kugirango rushobore kwakira no kohereza ibimenyetso bya electroniki.
Antenna ihuriweho na RF antenna: Antenna ihuriweho na RF isanzwe ikoreshwa mugutumanaho hagati yabasomyi ba RFID na tagi ya RFID. Bashakanye binyuze mumasangano asangiwe. Izi antenne mubisanzwe zimeze nkizunguruka kugirango habeho imbaraga za rukuruzi zisangiwe hagati yumusomyi wa RFID na tagi ya RFID.
Microstrip patch antenna: Mubisanzwe ni igipande cyoroshye cyicyuma gifatanye nindege yubutaka. Microstrip patch antenna yoroheje muburemere, ntoya mubunini, kandi inanutse mubice. Urusobe rugaburira hamwe nurusobekerane rushobora kubyara icyarimwe na antene, kandi bifitanye isano rya hafi na sisitemu yitumanaho. Inzira zicapuwe zahujwe hamwe, kandi ibishishwa birashobora gukorwa hifashishijwe uburyo bwa Photolithography, bidahenze kandi byoroshye kubyara umusaruro.
Antenna ya Yagi: ni antenne yicyerekezo igizwe na dipole ebyiri cyangwa zirenga igice. Bakunze gukoreshwa mukuzamura ibimenyetso byerekana ibimenyetso cyangwa kuyobora itumanaho ryitumanaho.
Antenne ishyigikiwe na Cavity: Ni antenne aho antenne na federasiyo bishyirwa mumyanya imwe yinyuma. Zikoreshwa cyane muri sisitemu ya RFID yumurongo mwinshi kandi irashobora gutanga ibimenyetso byiza kandi bihamye.
Antenna ya Microstrip umurongo: Ni antenne ntoya kandi yoroheje, ubusanzwe ikoreshwa mubikoresho bito nkibikoresho bigendanwa hamwe na tagisi ya RFID. Byubatswe kuva kumurongo wa microstrip itanga imikorere myiza mubunini buto.
Antenna: Antenne ishoboye kwakira no kohereza umuzenguruko uzengurutswe na electromagnetic waves. Mubisanzwe bikozwe mubyuma cyangwa urupapuro kandi bifite kimwe cyangwa byinshi byubatswe.
Hariho ubwoko bwinshi bwa antene kugirango ikoreshwe mubihe bitandukanye nkinshuro zitandukanye, intego zitandukanye, ibihe bitandukanye, nibisabwa bitandukanye. Buri bwoko bwa antenne bufite imiterere yihariye hamwe nibisabwa. Mugihe uhisemo antenne ikwiye ya RFID, ugomba guhitamo ukurikije ibisabwa byukuri nibisabwa nibidukikije.
