Te whakarōpūtanga me te kōwhiringa o te pūihi RFID UHF
Pūihi RFID UHFhe wāhanga tino nui o ngā taputapu pūmārō i roto i te pānui RFID, ngā rerekētanga Pūihi RFID UHF He pānga tika ki te tawhiti me te whānuitanga o te pānui. He momo rerekē ngā pūihi RFID UHF, he mea tino nui te whiriwhiri i te pūihi RFID UHF tika mō ia kaupapa.
E ai ki ngā rauemi rerekē
He Pūihi RFID PCB, pūihi RFID uku, pūihi pereti konumoheme te pūihi FPC, me ētahi atu. He painga me he ngoikoretanga o ia rauemi, ā, ka whakamahia i roto i ngā āhuatanga rerekē. Pērā i te pūihi RFID uku, he pumau te mahi me te rahi iti. E mōhio ana tātou ko te rahi iti rawa o te pūihi uku he 18X18 mm, tera pea he iti ake. Engari kāore te pūihi uku e pai mō te mahi nui rawa, ko te mea nui rawa atu i te mākete ko te pūihi RFID UHF 5dbi, te rahi 100*100mm. Mena he nui te rahi, kāore te hanga me te utu e rite ana ki te painga o te PCB me te pūihi konumohe. Ko te pūihi PCB UHF he pūihi whakanui nui, ā, koinei te whiringa a te nuinga o te tangata. Mō PCB Rfid pūihi, ka taea te tāuta i te anga hei whakatutuki i te whakamahinga o waho. Ko te āhuatanga nui o te pūihi FPC he ngāwari, he pai mō te nuinga o ngā hua hiko iti.
Te rerekētanga i waenga i ngā pūihi porowhita-polarized me ngā pūihi raina-polarized
Mō te whakapūtanga raina, ina rite te ahunga whakapūtanga o te pūihi whiwhi ki te ahunga whakapūtanga raina (te ahunga o te mara hiko), ko te tohu te mea pai rawa atu (ko te whakaaturanga o te ngaru hikohiko i te ahunga whakapūtanga te mea nui rawa atu). I te mea he rerekē ake te ahunga whakapūtanga o te pūihi whiwhi i te ahunga whakapūtanga raina, ka iti ake te tohu (ka heke tonu te whakaaturanga). Ina he orthogonal te ahunga whakapūtanga o te pūihi whiwhi ki te ahunga whakapūtanga raina (te ahunga mara aukume), ko te tohu i puta ko te kore (ko te whakaaturanga he kore). He nui ake ngā whakaritenga mō te tikanga whakapūtanga raina mō te ahunga o te pūihi. Kāore i te maha te whakamahi i ngā pūihi whakapūtanga raina, hei tauira, me whakapūtanga raina ngā pūihi i roto i ngā whakamātautau rūma ngaruiti-anechoic.
Mō ngā pūihi porowhita-polarized, he rite tonu te tohu whakaoho ahakoa te ahunga polarization o te pūihi whiwhi, ā, kāore he rerekētanga (he rite tonu te whakaaturanga o ngā ngaru hikohiko ki tētahi ahunga). Nō reira, mā te whakamahinga o te polarization porowhita ka iti ake te aro o te pūnaha ki te aronga o te pūihi (ko te aronga i konei ko te aronga o te pūihi, he rerekē i te aronga o te pūnaha ahunga i whakahuatia i mua ake nei). Nō reira, ka whakamahia ngā pūihi porowhita-polarized i te nuinga o ngā āhuatanga i roto i ngā kaupapa IoT.
Te rerekētanga i waenga i te pūihi RFID tata-mara me te pūihi RFID tawhiti-mara
E ai ki te ingoa, pūihi RFID tata-mara He pūihi tēnei mō te pānui tata. Ka arotahi te hihi pūngao ki te awhe tata i runga ake i te pūihi, e whakarite ana i te pānga pānui tata me te kore e hē te pānui, te pānui aho rānei i ngā tohu RFID e karapoti ana. Ko te nuinga o ana tono he mea aro ki ngā kaupapa e hiahia ana kia pānuihia i te tawhiti tata me te kore e hē te pānui i ngā tohu e karapoti ana i te pūihi, pērā i te whakahaere taonga whakapaipai, te whakahaere taputapu hauora, te whakataunga hūpāmakete kore tangata, me ngā kāpata taputapu atamai me ētahi atu.
He nui te koki hihi pūngao o te pūihi RFID tawhiti-papa, ā, he tawhiti hoki. Mā te pikinga ake o te whakanui me te rahi o te pūihi, ka piki ake te whānuitanga hihi me te tawhiti pānui. I roto i te whakamahinga, e hiahiatia ana ngā pūihi tawhiti-papa katoa mō te pānui mamao, ā, ka whakamahia hoki e te kaipānui ringaringa ngā pūihi tawhiti-papa. Hei tauira, te whakahaere ratonga whare putunga, te whakahaere rauemi wheketere me te rarangi taonga, me ētahi atu.
