Kupatsanura uye kusarudzwa kweantenna yeRFID UHF
Kanyanga yeRFID UHFchikamu chakakosha chemidziyo yehardware mukuverenga kweRFID, zvakasiyana RFID UHF kanyanga Zvinokanganisa zvakananga daro rekuverenga uye daro rekuverenga. Maantenna eRFID UHF ndeemhando dzakasiyana-siyana, nzira yekusarudza antenna yeRFID UHF yakakodzera zvichienderana nemapurojekiti akasiyana-siyana inokosha zvikuru.
Zvichienderana nezvinhu zvakasiyana
Pane Kanyanga yeRFID yePCB, kanyanga yeRFID yedongo, kanyanga yearuminiyamu ndirouye FPC antenna, nezvimwewo. Chinhu chimwe nechimwe chine zvakanakira nezvachinokanganisa uye chinoshandiswa mumamiriro akasiyana. Sezvakaita ceramic RFID antenna, ine mashandiro akagadzikana uye saizi diki. Tinoziva kuti saizi diki yeceramic antenna i18X18 mm, hongu, panogona kunge paine diki. Asi ceramic antenna haina kukodzera kuita yakakura zvakanyanya, yakakura pamusika iRFID UHF antenna 5dbi, saizi 100*100mm. Kana saizi yacho yakakura, zvese kugadzirwa uye mutengo hazvina zvakanakira sePCB nealuminium antenna. UHF PCB antenna ilarge gain antenna uye ndiyo sarudzo yevanhu vazhinji. PCB Rfid antenna, ganda rinogona kuiswa kuti rienderane nekushandiswa kwekunze. Hunhu hukuru hweantenna yeFPC hunochinjika, hwakakodzera zvigadzirwa zvidiki zvemagetsi.
Musiyano uripo pakati peantenna dzakatenderera nedzakatenderera nedzakatenderera
Pakupolarization kwemutsetse, kana nzira yekupolarization yeantenna inogamuchira ichiwirirana nenzira yekupolarization yemutsetse (nzira yemunda wemagetsi), chiratidzo ndicho chakanakisa (kuratidzwa kwewave yemagetsi munzira yekupolarization ndiko kwakakura). Kusiyana neizvi, sezvo nzira yekupolarization yeantenna inogamuchira yakasiyana zvakanyanya nenzira yekupolarization yemutsetse, chiratidzo chinova chidiki (kuratidzwa kunoderera nguva dzose). Kana nzira yekupolarization yeantenna inogamuchira iri orthogonal kune nzira yekupolarization yemutsetse (nzira yemagnetic field), chiratidzo chakakonzerwa zero (kuratidzwa zero). Nzira yekupolarization yemutsetse ine zvinodiwa zvepamusoro panzira yeantenna. Maantenna ane polarized linear haawanzo shandiswa, semuenzaniso, maantenna ari mukuyedza kwekamuri re microwave anechoic anofanira kunge ari maantenna ane polarized linearly.
Kune maantenna ane polarized denderedzwa, chiratidzo chinokonzereswa chakafanana zvisinei nekwakanangana kwepolarization kweantenna inogamuchira, uye hapana musiyano (kuratidzwa kwemafungu emagetsi kune chero divi kwakafanana). Nokudaro, kushandiswa kwepolarization yakatenderera kunoita kuti system isanyanya kugadzikana nekwakanangana kweantenna (pano kwakanangana ndiko kwakanangana kweantenna, izvo zvakasiyana nekwakanangana nesystem yambotaurwa). Naizvozvo, maantenna ane polarized akatenderera anoshandiswa mumamiriro mazhinji ezvinhu mumapurojekiti eIoT.
Musiyano uripo pakati peantenna yeRFID iri pedyo nemunda uye antenna yeRFID iri kure
Sezvinoreva zita racho, kanyanga yeRFID iri pedyo iantenna yekuverenga zviri pedyo. Mwaranzi yesimba iri munzvimbo iri pedyo pamusoro peantenna, izvo zvinoita kuti kuverenga kuri pedyo kuve nyore pasina kuverenga zvisizvo kana kuverenga RFID tags dzakapoteredza. Mashandisirwo ayo anonyanya kunangana nemapurojekiti anoda kuverengwa ari pedyo pasina kuverenga zvisizvo matagi akatenderedza antenna, akadai sekutarisira zvishongo, kutarisira michina yekurapa, nzvimbo yezvitoro zvisina vanhu, uye makabati ezvishandiso akangwara nezvimwewo.
Antena yeRFID yefar-field ine kona yakakura yemwaranzi uye daro refu. Nekuwedzera kwekuwedzera kweantena nehukuru, huwandu hwemwaranzi uye daro rekuverenga zvinowedzera zvinoenderana. Pakushandisa, antena dzese dzefar-field dzinodiwa pakuverenga uri kure, uye muverengi wemuruoko anoshandisawo antena dzefar-field. Semuenzaniso, manejimendi ekuchengetedza zvinhu muwarehouse, kutonga kwezvinhu zvefekitori uye kuchengetedzwa kwezvinhu, nezvimwewo.
