Iyo RFID antenna chikamu chakakosha kuona basa rekuverenga reRFID hardware mudziyo.Musiyano weantenna unobata zvakananga kureba kwekuverenga, huwandu, nezvimwe, uye antenna chinhu chakakosha chinokanganisa chiyero chekuverenga.Iyo antenna yeRFID muverengiinogona kunyanya kukamurwa kuita mutsara polarization uye denderedzwa polarization zvinoenderana neiyo simba modhi.
Iyo polarization yeantenna inoreva mutemo wekuti kutungamira kwemagetsi emunda vector inoshanduka nenguva mune yakanyanya radiation kutungamira kweantenna.Akasiyana RFID masisitimu anoshandisa akasiyana antenna polarization nzira.Mamwe maapplication anogona kushandisa linear polarization, semuenzaniso, pamutsetse wegungano, chinzvimbo chemagetsi tag chakanyatsogadziriswa, uye antenna yemagetsi tag inogona kushandisa linear polarization.Asi muzviitiko zvakawanda, sezvo kutariswa kweiyo tag yemagetsi kusingazivikanwe, mazhinji masisitimu eRFID anoshandisa denderedzwa polarized antennas kuderedza kunzwisiswa kweRFID system kune kutaridzika kweiyo tag yemagetsi.Zvinoenderana nechimiro chetrajectory, polarization inogona kukamurwa kuita mutsara polarization, denderedzwa polarization uye elliptical polarization, pakati peiyo mutsara polarization uye denderedzwa polarization inonyanya kushandiswa.
RFID linearly polarized antenna
Iyo electromagnetic wave inoburitswa nemuverengi antenna yeiyo linearly polarized antenna ine mutsara, uye nzvimbo yayo yemagetsi ine kutungamira kwakasimba, uye ine zvinotevera maitiro:
1) Radio frequency simba inoburitswa kubva kune antenna mumutsara fashoni;
2) Iyo mutsara danda rine unidirectional electromagnetic munda, iyo yakasimba kupfuura denderedzwa polarized antenna, asi huwandu hwakatetepa uye hwakareba;
3) Kuenzaniswa nedenderedzwa polarized antenna, iyo-nzira imwe yekuverenga kureba, asi nekuda kwekutungamira kwakasimba, hupamhi hwekuverenga hwakatetepa;
4) Matagi (Identification Objects) akachinjirwa kutungamira kwekutsunga kwekufamba
Kana iyo RFID tag ichienderana neantenna yemuverengi, iyo linearly polarized antenna ine mwero wekuverenga uri nani.Naizvozvo, iyo linearly polarized antenna inowanzo shandiswa kuverenga ma tag ane mafambiro anozivikanwa, senge mapallets.Sezvo iyo electromagnetic wave beam yeantenna inogumira kune yakamanikana mukati meiyo ndege saizi yeanoverenga antenna, iro simba rinenge rakanyungudika uye rinogona kupinda mukati mezvinhu zvine hunyoro hwepamusoro.Naizvozvo, ine simba rinopinda riri nani rezvinhu zvine density yepamusoro uye inokodzera zvinhu zvakakura uye zvakakura-density yekuzivisa zvinhu, iyo linearly polarized antenna inopira hupamhi hwehuwandu hwekuverenga mukutsinhana nekunzwa kweki uye kureba kweiyo. -nzira yekuverenga kureba.Naizvozvo, antenna yemuverengi inofanirwa kuenderana nendege yezita kana uchiishandisa, kuitira kuti uve nekuverenga kwakanaka.
RFID Circularly Polarized Antenna
Iyo electromagnetic field emission ye circularly polarized antenna is helical beam, ine zvinotevera maitiro:
1) Antenna RF simba rinoburitswa nedenderedzwa helical antenna;
2) Iyo denderedzwa helical beam ine multi-directional electromagnetic munda, uye huwandu hwenzvimbo yemagetsi yakakura, asi simba rayo idiki pane reiyo linearly polarized antenna;
3) Nzvimbo yekuverenga yakapamhama, asi kana ichienzaniswa neiyo mutsara polarization antenna, kunzwisiswa kweiyo-nzira tag kwakadzikira uye chinhambwe chekuverenga ipfupi;
4) Inoshanda kune ma tag (kuzivikanwa zvinhu) ane mafambiro asina chokwadi.
Iyo denderedzwa yemagetsi danda reiyo denderedzwa polarized antenna inokwanisa kutumira kunze munzira dzese panguva imwe chete.Paunenge uchisangana nezvipingamupinyi, iyo electromagnetic danda re denderedzwa polarized antenna ine kuchinjika kwakasimba uye kugona kutsauka, izvo zvinowedzera mukana wekuverenga weiyo label inopinda mu antenna kubva kumativi ese, saka izvo zvinodikanwa zvekunamira kwemavara uye nzira yekufamba zvinoshivirira;Nekudaro, hupamhi hwedanda redenderedzwa rinounzawo kudzikiswa kwehukama mukusimba kweiyo electromagnetic wave, kuitira kuti tag ingogona kunakidzwa nechikamu cheiyo electromagnetic wave simba mune imwe nzira, uye daro rekuverenga rakapfupikiswa.Naizvozvo, iyo denderedzwa polarized antenna inokodzera nguva apo mafambiro ekufamba kweti (chinhu chakazivikanwa) chisingazivikanwe, senge nzvimbo inotakura zvinhu yenzvimbo yekugovera.
Zvinoenderana nekushandiswa uye hunhu hwechigadzirwa, ShenzhenHandheld-Wirelessrfid zvishandiso zvinonyanya kutora mutsara polarization uye denderedzwa polarization mhinduro kuzadzisa zvinodiwa nemapurojekiti akasiyana, ayo anogona kuiswa kune eventory stocktaking, asset inventory uye mamwe mapurojekiti, uye akashandiswa zvakanyanya mukugadzira zvinhu, mushonga wechipatara, Simba, mari, kuchengetedzwa kweveruzhinji, dzidzo, mutero, zvekufambisa, kushanya, zvitoro, kuwacha, mauto nemamwe maindasitiri.
