Peb txheej txheem los ua RFID tag antennas

Nyob rau hauv tus txheej txheem ntawm kev sib txuas lus wireless, lub kav hlau txais xov yog ib qho tseem ceeb ntawm cov khoom siv, thiab RFID siv xov tooj cua nthwv dej los xa cov ntaub ntawv, thiab kev tsim thiab txais xov tooj cua nthwv dej yuav tsum tau paub los ntawm tus kav hlau txais xov. Thaum lub cim hluav taws xob nkag mus rau thaj chaw ua haujlwm ntawm tus nyeem ntawv kav hlau txais xov, lub kav hlau txais xov hluav taws xob yuav tsim kom muaj hluav taws xob txaus kom tau txais lub zog kom qhib tau.

Rau RFID system, kav hlau txais xov yog ib feem tseem ceeb, uas yog ze rau kev ua haujlwm ntawm lub kaw lus.

Tam sim no, raws li qhov sib txawv ntawm cov kav hlau txais xov hlau, cov khoom siv thiab cov txheej txheem tsim khoom, RFID tag kav hlau txais xov tuaj yeem muab faib ua pawg raws li hauv qab no: etched antennas, luam ntawv antennas, coiled antennas, additive antennas, ceramic antennas, thiab lwm yam. siv antennas Cov txheej txheem tsim khoom yog thawj peb.

Coil qhov txhab kav hlau txais xov

Kev tsim cov txheej txheem ntawm tooj liab hlau winding RFID tag kav hlau txais xov yog feem ntau ua tiav los ntawm lub tshuab tsis siv neeg winding, uas yog, cov kua roj vanish yog ncaj qha rau ntawm lub hauv paus cab kuj zaj duab xis, thiab tooj liab hlau uas tsis tshua muaj melting point ci varnish yog siv los ua cov khoom siv hauv paus. ntawm RFID tag kav hlau txais xov. , thiab thaum kawg mechanically kho cov hlau thiab cov substrate nrog nplaum, thiab cua ib tug xov tooj ntawm lem raws li txawv zaus yuav tsum tau.

Nws feem ntau yog siv nyob rau hauv qis-frequency RFID systems, thiab high-frequency kuj siv tau. Nta: tus nqi siab, qeeb ntau lawm ceev.

Etching

Txoj kev etching tseem hu ua etching etching method. Ua ntej, ib txheej ntawm tooj liab lossis txhuas nrog lub thickness ntawm li 20 hli yog them rau ntawm lub hauv paus cab kuj, thiab lub vijtsam luam ntawv phaj ntawm cov duab zoo ntawm tus kav hlau txais xov kuj tau tsim, thiab qhov kev tawm tsam yog luam tawm los ntawm kev tshuaj ntsuam luam ntawv. Nyob rau saum npoo ntawm tooj liab lossis txhuas, lub hauv paus tooj liab lossis txhuas yog tiv thaiv corrosion, thiab cov seem yog yaj los ntawm tus neeg sawv cev corrosive.

High-frequency RFID systems feem ntau siv thiab muaj cov yam ntxwv ntawm kev ua haujlwm siab, tus nqi siab, thiab kev tsim khoom tsawg.

Txawm li cas los xij, vim yog cov tshuaj tiv thaiv erosion siv nyob rau hauv cov txheej txheem etching, muaj teeb meem ntawm cov txheej txheem ntev ntws thiab ntau cov khib nyiab thiab cov dej khib nyiab, uas yooj yim ua rau muaj kuab paug rau ib puag ncig, yog li kev lag luam tau sim nrhiav qhov zoo dua. lwm txoj.

Luam tus kav hlau txais xov

Lub kav hlau txais xov Circuit Court yog luam ncaj qha los yog luam tawm ntawm lub substrate nrog tshwj xeeb conductive number case los yog silver paste, thiab qhov ntau mature yog gravure printing los yog silk screen printing. Kev tshuaj ntsuam luam ntawv txuag cov nqi rau qee qhov, tab sis tus number case siv cov nyiaj siv hluav taws xob nrog cov ntsiab lus siab ntawm li 70 feem pua ​​​​kom tau txais lub kav hlau txais xov ntawm 15 thiab 20um, uas yog cov txheej txheem luam ntawv tuab, thiab tus nqi siab.

Feem ntau siv hauv UHF thiab HF RFID systems, nta: cov zis loj, tus nqi qis, thiab tsis muaj zog.
