Pakati pematekinoroji ekutaurirana asina waya, hukama huripo pakati pemudziyo we transceiver usina waya ne antenna yeRFID system ndiyo inonyanya kukosha. Mumhuri yeRFID, antenna neRFID inhengo dzakakosha zvakaenzana. RFID ne antenna zvinoenderana uye hazviparadzanisike. Ingave iri RFID reader kana RFID tag, ingave iri high-frequency RFID technology kana ultra-high-frequency RFID technology, haiparadzanisike kubva kukanyanga.
RFIDkanyangaishandurudzo inoshandura mafungu anotungamirwa anopararira patambo yekutumira kuita mafungu emagetsi anopararira munzvimbo isina muganho (kazhinji nzvimbo yakasununguka), kana zvakasiyana. Antena chikamu chemidziyo yeredhiyo inoshandiswa kutumira kana kugamuchira mafungu emagetsi. Simba remagetsi rinobuda muradio frequency signal rinoendeswa kuantenna kuburikidza ne feeder (tambo), uye rinoburitswa neantenna muchimiro chemafungu emagetsi. Mushure mekunge electromagnetic wave yasvika panzvimbo inogamuchira, inogashirwa ne antenna (chikamu chidiki chete chesimba chinogashirwa) uye chinotumirwa kuradio receiver kuburikidza ne feeder, sezvakaratidzwa mumufananidzo uri pazasi.
Nheyo yekuburitsa mafungu emagetsi kubva kumaantenna eRFID
Kana waya iine simba remagetsi rinochinja-chinja, rinoburitsa mafungu emagetsi, uye kugona kwayo kuburitsa mwaranzi kwakabatana nehurefu nechimiro chewaya. Kana daro riri pakati pewaya mbiri iri pedyo zvikuru, simba remagetsi rinosungirirwa pakati pewaya mbiri, saka mwaranzi haina simba; kana waya mbiri dzakapararira, simba remagetsi rinopararira munzvimbo yakapoteredza, saka mwaranzi inowedzerwa. Kana kureba kwewaya kuri kudiki pane wavelength yewaya remagetsi rinopfuudzwa, mwaranzi haina simba; kana kureba kwewaya kwakaenzana newavelength yewaya remagetsi rinopfuudzwa, simba riri pawaya rinowedzera zvakanyanya, zvichiita mwaranzi yakasimba. Waya yakatwasuka yataurwa pamusoro apa inogona kugadzira mwaranzi yakakosha inowanzonzi oscillator, uye oscillator iantenna iri nyore.
Kana mafungu emagetsi emagetsi akareba, saizi yeantenna inokura. Simba rinoda kuratidzwa, saizi yeantenna inokurawo.
RFID antenna gwara
Mafungu emagetsi anoburitswa neantenna anonongedzera. Pamugumo weantenna, gwara rinoreva kugona kweantenna kuburitsa mafungu emagetsi nenzira yakati. Kune rimwe divi rinogamuchira, zvinoreva kugona kweantenna kugamuchira mafungu emagetsi kubva kumativi akasiyana. Girafu yebasa iri pakati pezviratidzo zvemwaranzi yeantenna uye nzvimbo dzinoenderana ndiyo patani yeantenna. Kuongorora patani yeantenna kunogona kuongorora hunhu hwemwaranzi yeantenna, kureva kugona kweantenna kutumira (kana kugamuchira) mafungu emagetsi munzvimbo dzese dziri muchadenga. Gwara reantenna rinowanzo miririrwa nema curves ari pa vertical plane uye horizontal plane inomiririra simba remafungu emagetsi anoburitswa (kana kugamuchirwa) munzira dzakasiyana.
Nekuchinja zvinoenderana nechimiro chemukati cheantenna, kutungamira kweantenna kunogona kuchinjwa, nokudaro kuumba mhando dzakasiyana dzeantenna dzine hunhu hwakasiyana.
RFID antenna kuwana
Kuwana antenna kunotsanangura huwandu hweantena inoburitsa simba rekupinda nenzira yakabatana. Kubva pamaonero epatani, kana lobe huru yakatetepa, lobe yedivi idiki, uye kuwedzera kwekuwedzera. Muinjiniya, kuwedzera kweantena kunoshandiswa kuyera kugona kweantena kutumira nekugamuchira masaini munzira yakatarwa. Kuwedzera kuwedzera kwekuwedzera kunogona kuwedzera kufukidzwa kwenetwork munzira yakati, kana kuwedzera mukana wekuwedzera mukati menzvimbo yakati. Pasi pemamiriro akafanana, kuwedzera kwekuwedzera, ndiko kuwedzera kwewave redhiyo.
Kupatsanura antenna dzeRFID
Antena yeDipole: Inonziwo symmetrical dipole antenna, ine waya mbiri dzakatwasuka dzine ukobvu hwakafanana uye kureba kwakafanana dzakarongwa mumutsara wakatwasuka. Chiratidzo chinopihwa kubva kuma endpoints maviri ari pakati, uye kugoverwa kwemagetsi kwakati kuchagadzirwa pamaoko maviri edipole. Kugoverwa kwemagetsi uku kuchamutsa munda wemagetsi munzvimbo yakatenderedza antena.
Antena yeCoil: Ndiyo imwe yeantena dzinoshandiswa zvakanyanya muRFID systems. Dzinowanzogadzirwa newaya dzakasungirirwa kuita denderedzwa kana rectangular kuti dzikwanise kugamuchira nekutumira masaini emagetsi.
Antena yeRF yakabatana neInductively: Antena yeRF yakabatana neInductively inowanzo shandiswa pakutaurirana pakati pevaverengi veRFID nematagi eRFID. Anobatanidza kuburikidza nemunda wemagineti wakagovaniswa. Antena idzi dzinowanzo kuve muchimiro chespiral kugadzira munda wemagineti wakagovaniswa pakati pemuverengi weRFID netagi yeRFID.
Antena yeMicrostrip patch: Kazhinji inenge iri jira rakatetepa resimbi rakabatana nepasi. Antena yeMicrostrip patch ine huremu hwakareruka, diki, uye yakatetepa. Network yekudyisa nekubatanidza inogona kugadzirwa panguva imwe chete neantenna, uye yakabatana zvakanyanya nesystem yekutaurirana. Maseketi akadhindwa anobatanidzwa pamwe chete, uye mapatch anogona kugadzirwa achishandisa maitiro ephotolithography, ayo asingadhuri uye ari nyore kugadzira.
Antena yeYagi: iantenna inotungamira ine ma dipoles maviri kana anopfuura ehafu-wave. Anowanzo shandiswa kuwedzera simba remasaini kana kuita kutaurirana kwewaya pasina waya.
Antena ine cavity backed: Iantenna umo antenna ne feeder zvinoiswa mu back cavity imwe chete. Zvinowanzoshandiswa muma RFID systems ane frequency yakakwira uye zvinogona kupa masaini akanaka uye kugadzikana.
Antena yeMicrostrip linear: Iantenna diki uye yakatetepa, inowanzo shandiswa mumidziyo midiki yakaita semafoni uye maRFID tag. Yakagadzirwa nemitsetse yemicrostrip inoita kuti ishande zvakanaka muhukuru hudiki.
Kanyanga yeSpiral: Antena inokwanisa kugamuchira nekutumira mafungu emagetsi ane polarized circular. Anowanzo gadzirwa newaya yesimbi kana sheet metal uye ane chimiro chimwe kana kupfuura chakaita se spiral.
Kune mhando dzakawanda dzeantenna dzekushandisa mumamiriro ezvinhu akasiyana akadai sema frequency akasiyana, zvinangwa zvakasiyana, zviitiko zvakasiyana, uye zvinodiwa zvakasiyana. Rudzi rwega rweantenna rune hunhu hwarwo hwakasiyana uye mamiriro ezvinhu anoshanda. Pakusarudza antenna yeRFID yakakodzera, unofanirwa kusarudza zvichienderana nezvinodiwa chaizvo zvekushandisa uye mamiriro ekunze.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
