Txoj Kev Txhim Kho Ntawm RFID Card

1940-1950: Vim muaj kev txhim kho thiab kev nce qib ntawm radar thev naus laus zis, RFID thev naus laus zis tau muab los, thiab lub hauv paus theoretical rau RFID yug hauv xyoo 1948.
1950-1960: Cov neeg pib tshawb nrhiav RFID thev naus laus zis, tab sis tsis tau tawm hauv kev tshawb fawb hauv chav kuaj.
1960-1970: Cov kev xav cuam tshuam txuas ntxiv txhim kho thiab cov txheej txheem no tau pib siv rau hauv kev xyaum.
1970-1980: RFID thev naus laus zis tau hloov kho tas li, kev tshawb fawb cov khoom lag luam tau maj mam nce zuj zus, thiab kev sim RFID tau pib nrawm dua. Thiab pom tau hais tias daim ntawv thov ntawm lwm yam systems.
1980-1990: RFID thev naus laus zis thiab cov khoom lag luam cuam tshuam tau tsim thiab siv hauv kev ua lag luam, thiab ntau yam kev thov tau tshwm sim.
1990-2000: Cov neeg tau pib muab qhov tseem ceeb rau kev tsim qauv ntawm RFID, thiab RFID systems tuaj yeem pom hauv ntau qhov chaw ntawm lub neej.
Tom qab xyoo 2000, tib neeg feem ntau tau lees paub qhov tseem ceeb ntawm cov teeb meem kev teeb tsa, thiab ntau yam ntawm RFID cov khoom tau ntxiv dag zog thiab tsim. Ob qho tib si nquag, passive, thiab semi active electronic labels tau pib tsim. Cov nqi tsim khoom muaj feem cuam tshuam tau qis dua, thiab daim ntawv thov daim teb tau maj mam nce.
Xyoo 2020, RF circuits tau siv dav hauv kev sib txuas lus hauv kev sib txuas lus wireless, xws li kev sib txuas lus satellite mus rau lub xov tooj ntawm tes, WiFi, thiab tsheb kauj vab sib koom. Tsim yog lub hauv paus ntawm RF kev lag luam saw, thiab Xov tooj cua Frequency Electronic Design Automation (EDA) software yog qhov kawg ntawm RF Circuit Court tsim thiab lub hauv paus tseem ceeb ntawm RF kev lag luam.
Cov txheej txheem thev naus laus zis ntawm RFID tau txuas ntxiv txhim kho thiab tsim, thiab tib neeg tau tsim RFID thev naus laus zis uas yog tib lub cim hluav taws xob hluav taws xob, nyeem ntawv hluav taws xob ntau, wireless nyeem tau thiab sau tau, thiab haum rau cov khoom siv ceev ceev. Ntxiv mus, cov khoom muaj feem xyuam kuj tau nkag mus rau peb lub neej thiab pib siv dav.
