I-RFID antenna iyingxenye ebalulekile yokuthola umsebenzi wokufunda we-RFID hardware device.Umehluko we-antenna uthinta ngqo ibanga lokufunda, ububanzi, njll., futhi uthi luyisici esibalulekile esithinta izinga lokufunda.I-antenna yeUmfundi we-RFIDingahlukaniswa ngokuyinhloko ibe yi-linear polarization kanye ne-circular polarization ngokuya ngemodi yamandla.

I-polarization ye-antenna ibhekisela emthethweni wokuthi isiqondiso se-vector yenkundla kagesi sishintsha ngokuhamba kwesikhathi ekuqondeni okuphezulu kwemisebe yothi.Amasistimu e-RFID ahlukene asebenzisa izindlela ezihlukene zokuhlukanisa i-antenna.Ezinye izinhlelo zokusebenza zingasebenzisa i-polarization yomugqa, isibonelo, emugqeni wokuhlanganisa, indawo yethegi ye-elekthronikhi imisiwe, futhi uthi lwethegi ye-elekthronikhi lungasebenzisa i-polarization yomugqa.Kodwa ezikhathini eziningi, njengoba ukuma kwethegi ye-elekthronikhi kungaziwa, izinhlelo eziningi ze-RFID zisebenzisa izimpondo eziyisiyingi ukuze zinciphise ukuzwela kwesistimu ye-RFID ekuqondisweni kwethegi ye-elekthronikhi.Ngokusho komumo we-trajectory, i-polarization ingahlukaniswa ibe i-polarization yomugqa, i-circular polarization kanye ne-elliptical polarization, phakathi kwayo i-polarization yomugqa kanye ne-circular polarization kusetshenziswa kabanzi.

I-RFID ethi i-polarized antenna

I-electromagnetic wave ekhishwa uthi lomfundi we-antenna e-polarized linearly, futhi inkambu yawo kazibuthe inokuqondisa okuqinile, futhi inezici ezilandelayo:
1) Amandla efrikhwensi yomsakazo akhishwa othini ngendlela yomugqa;
2) I-linear beam inenkundla kazibuthe engaqondile, enamandla kune-antenna eyi-polarized, kodwa ububanzi buncane futhi bude;
3) Uma kuqhathaniswa ne-antenna eyi-polarized, ibanga lokufunda indlela eyodwa lide, kodwa ngenxa yokuqondisa okuqinile, ububanzi bokufunda buncane;
4) Amathegi (Izinto Zokuhlonza) alungiselwe isiqondiso sokunqunywa kohambo

Uma ithegi ye-RFID ihambisana ne-antenna yomfundi, i-antenna eyenziwe nge-polarized inezinga lokufunda elingcono.Ngakho-ke, i-antenna ye-polarized polarized ngokuvamile isetshenziselwa ukufunda amathegi aziwa indlela yawo yokuhamba, njengamaphalethi.Njengoba i-electromagnetic wave beam ye-antenna ikhawulelwe ebangeni elincane ngaphakathi kosayizi wendiza ye-antenna yomfundi, amandla agxile kakhulu futhi angangena ezintweni ezinokuminyana okuphezulu.Ngakho-ke, inamandla okungena angcono wezinto ezisetshenziswayo ezinokuminyana okuphezulu futhi ifanele izinto zokuhlonza ezinkulu nezinokuminyana okuphezulu, i-antenna ehlukaniswe umugqa empeleni idela ububanzi bebanga lokufunda ukuze ithole ukuzwela kwethegi nobude bayo. -ibanga lokufunda indlela.Ngakho-ke, i-antenna yomfundi kufanele ihambisane nendiza yelebula lapho uyisebenzisa, ukuze ibe nomthelela omuhle wokufunda.

I-RFID Circularly Polarized Antenna

I-electromagnetic field emission of the circularly polarized antenna yi-helical beam, enezici ezilandelayo:
1) Amandla e-Antenna RF akhishwa ithiyo eliyindilinga eliyindilinga;
2) I-helical beam eyindilinga inenkambu ye-electromagnetic enezinhlangothi eziningi, futhi ububanzi benkambu ye-electromagnetic bubanzi, kodwa amandla ayo mancane kunalawo we-antenna e-polarized;
3) Isikhala sokufunda sibanzi, kodwa uma siqhathaniswa ne-antenna ye-polarization, ukuzwela kwethegi yendlela eyodwa kuphansi futhi ibanga lokufunda lifushane;
4) Isebenza kumathegi (izinto ezihlonzayo) lapho indlela yokuhamba ingaqinisekile.

I-electromagnetic beam eyisiyingi yothi oluyindilinga iyakwazi ukuthumela izinhlangothi zonke ngasikhathi sinye.Lapho uhlangabezana nezithiyo, i-electromagnetic beam ye-antenna eyindilinga evulekile inokuguquguquka okuqinile nekhono lokuchezuka, okwandisa amathuba okufunda elebula elingena othini lisuka kuzo zonke izinhlangothi, ngakho-ke izidingo zokunamathela kwelebula kanye nendlela yokuhamba ziyabekezelela;Kodwa-ke, ububanzi bomugqa oyindilinga nakho kuletha ukuncipha okuhlobene kokuqina kwegagasi kagesi, ukuze ithegi ijabulele ingxenye yamandla kazibuthe wegagasi eliya ohlangothini oluthile, futhi ibanga lokufunda lifinyezwe ngokuqhathaniswa.Ngakho-ke, i-antenna eyisiyingi eyi-polarized ifanele izikhathi lapho isiqondiso sokuhamba komaka (into ekhonjiwe) ingaziwa, njengendawo yebhafa yempahla yesikhungo sokusabalalisa.

Ngokusho kwesicelo kanye nezici zomkhiqizo, i-ShenzhenI-Handheld-WirelessAmadivaysi e-rfid asebenzisa izixazululo ze-linear polarization kanye ne-circular polarization ukuze ahlangabezane nezidingo zamaphrojekthi ahlukene, angasetshenziswa ekuthathweni kwempahla, ukusungula impahla kanye namanye amaphrojekthi, futhi asetshenziswe kabanzi ku-logistics, imithi yesibhedlela, Amandla, ezezimali, ukuphepha komphakathi, imfundo, intela, ezokuthutha, ezokuvakasha, ukudayisa, ilondolo, ezempi nezinye izimboni.
