Anteenada RFID waa qayb muhiim ah oo lagu xaqiijinayo shaqada akhriska ee qalabka hardware RFID.Farqiga anteenadu waxay si toos ah u saamaysaa fogaanta akhriska, kala duwanaanta, iwm., anteenaduna waa arrin muhiim ah oo saameeya heerka akhriska.Anteenada eeAkhristaha RFIDwaxaa inta badan loo kala saari karaa polarization linear iyo polarization wareeg ah iyadoo loo eegayo habka tamarta.

Polarization of anteenada waxaa loola jeedaa sharciga in jihada vector beerta korantada isbedel waqti in jihada ugu badan ee shucaaca anteenada.Nidaamyada RFID ee kala duwan waxay isticmaalaan habab kala duwan oo anteeno ah.Codsiyada qaarkood waxay isticmaali karaan polarization linear, tusaale ahaan, on line kulanka, booska summada elektarooniga ah asal ahaan go'an, iyo anteenada ee summada elektarooniga ah isticmaali kartaa polarization toosan.Laakiin marar badan, maadaama jihaynta summada elektaroonigga ah aan la garanayn, nidaamyada RFID intooda badani waxay isticmaalaan anteenooyin wareeg ah si ay u yareeyaan dareenka nidaamka RFID ee jihaynta summada elektaroonigga ah.Sida laga soo xigtay qaabka dariiqa, polarization waxaa loo qaybin karaa polarization linear, polarization wareeg ah iyo elliptical polarization, kuwaas oo ka mid ah polarization toosan iyo polarization wareeg ah ayaa aad loo isticmaalo.

RFID anteeno toosan

Hirarka korantada ee ay soo saarto anteenada akhristaha ee anteenada toosan ee polarized waa toosan, goobteeda korantadana waxa ay leedahay jihayn adag, waxayna leedahay sifooyinka soo socda:
1) Tamar inta jeer ee raadiyaha waxaa laga soo saaraa anteenada qaab toosan;
2) Laydhka toosan waxa uu leeyahay goob koronto-magneteed aan jiho lahayn, kaas oo ka xoog badan anteenada wareegta ah, laakiin kala duwanaanshuhu waa ka sii dhuuban yahay oo dheer yahay;
3) Marka la barbardhigo anteenada wareegta ah, masaafada hal-jidka ah ee wax-akhrisku way dheertahay, laakiin jihaynta xooggan awgeed, ballaca akhrisku wuu sii yaraanayaa;
4) Tags (Waxyaabaha Aqoonsiga) ee loo habeeyey jihada go'aaminta safarka

Marka sumadda RFID ay la mid tahay anteenada akhristaha, anteenada toosan waxay leedahay heer wax-akhris oo wanaagsan.Sidaa darteed, anteenada toosan ayaa guud ahaan loo isticmaalaa in lagu akhriyo tags kuwaas oo jihada socdaalkooda la yaqaan, sida sariiraha.Maadaama mowjadda korantada ee anteenadu ay ku kooban tahay cabbir cidhiidhi ah oo ka dhex jira cabbirka diyaaradda anteenada akhristaha, tamartu aad bay u urursan tahay oo waxay geli kartaa agab cufnaan sare leh.Sidaa darteed, waxay si fiican u leedahay awoodda wax-soo-saarka alaabta leh cufnaanta sare waxayna ku habboon tahay walxaha aqoonsiga cufnaanta iyo cufnaanta sare, anteenada toosan ee toosan waxay dhab ahaantii u huraysaa ballaadhka akhriska ee beddelka dareenka sumadda iyo dhererka mid ka mid ah. fogaanta akhriska jidka.Sidaa darteed, anteenada akhristuhu waa in ay la mid noqotaa diyaaradda calaamadda marka la isticmaalayo, si ay u yeelato saameyn akhris oo wanaagsan.

RFID Anteeno Wareeg ah

Sii daynta garoonka korantada ee anteenada wareegta ah waa laydhka helical, kaas oo leh sifooyinka soo socda:
1) Tamarta anteenada RF waxaa siidaaya anteeno helical wareeg ah;
2) Dhuxul wareeg ah oo helical ah waxay leedahay aag elektromagnetic ah oo jihooyin badan leh, baaxadda goobta korantada waa ka ballaaran tahay, laakiin xooggeedu wuu ka yar yahay kan anteenada toosan;
3) Meesha wax-akhrisku waa ballaadhan yahay, laakiin marka la barbar dhigo anteenada polarization-ka toosan, dareenka hal-jidka tag ayaa hooseeya, masaafada wax-akhristuna waa gaaban tahay;
4) Lagu dabaqi karo tags (walxaha aqoonsiga) kuwaas oo jihada ay u socdaan aan la hubin.

Beam elektromagnetic-ka wareegta ah ee anteeno wareeg ah ayaa awood u leh inay u dirto dhammaan jihooyinka isku mar.Markaad la kulanto caqabado, iftiinka korantada ee anteenada wareegta ah waxay leedahay dabacsanaan xooggan iyo awood leexasho, taas oo kordhisa suurtogalnimada akhriska ee calaamadda ka soo gelaysa anteenada dhammaan jihooyinka, markaa shuruudaha calaamadaynta ku dhegganaanta iyo jihada safarka ayaa ah mid dulqaad leh;Si kastaba ha ahaatee, ballaadhinta iftiinka wareegtadu waxay sidoo kale keenaysaa hoos u dhac ku yimaada xoogga hirarka korantada, si ay sumadu ugu raaxaysato oo keliya qayb ka mid ah tamarta hirarka korantada ee jiho gaar ah, iyo fogaanta akhrisku waa mid gaaban.Sidaa darteed, anteenada wareegta ah waxay ku habboon tahay waqtiyada aan la garanayn jihada loo socdo summada (shay la aqoonsaday), sida aagga kaydinta xamuulka ee xarunta qaybinta.

Sida laga soo xigtay codsiga iyo sifooyinka alaabta, ShenzhenGacanta-WirelessAaladaha rfid inta badan waxay qaataan dabaylaha toosan iyo xalalka polarization-ka wareegta ah si loo daboolo baahiyaha mashaariicda kala duwan, kuwaas oo lagu dabaqi karo kaydinta alaabada, alaabada hantida iyo mashaariicda kale, waxaana si weyn loogu isticmaalay saadka, daawada isbitaalada, awooda, maaliyadda, amniga guud. waxbarashada, canshuuraha, gaadiidka, dalxiiska, tafaariiqda, dhar dhaqidda, ciidamada iyo warshadaha kale.
