Hangarau auau reo irirangi ahokore: tātaritanga mātāpono me te tono maha-marae

Ko te RF (Auau Reo Irirangi) e pā ana ki ngā ngaru hikohiko me ngā auau i waenga i te 3kHz me te 300GHz, e whai wāhi nui ana ki ngā whakawhitiwhiti kōrero, te radar, te maimoatanga hauora, te whakahaere ahumahi me ētahi atu mara.

Ngā mātāpono taketake o te auau reo irirangi

Ka whakaputahia ngā tohu RF e ngā oscillator, ā, ka tukuna, ka horahia hoki ngā ngaru hiko auau-tiketike mā roto i ngā pūihi. Ko ngā momo pūihi noa ko ngā pūihi dipole, ngā pūihi haona me ngā pūihi papaki, e tika ana mō ngā āhuatanga tono rerekē. Ka whakahokia e te pito whiwhi te tohu RF ki ngā mōhiohio e taea ai te whakamahi mā roto i te demodulator hei whakatutuki i te tuku mōhiohio.

Ngā tikanga whakarōpū me te whakarerekētanga o te auau reo irirangi

E ai ki te auau, ka taea te wehewehe i te auau reo irirangi ki te auau iti (pērā i te whakawhitiwhiti kōrero pāho), te auau reo waenga (pērā i te whakawhitiwhiti kōrero pūkoro), me te auau reo teitei (pērā i te radar me te maimoatanga hauora). Ko ngā tikanga whakarerekētanga ko te AM (mō te tuku tere-iti), te FM (mō te tuku tere-waenga) me te PM (mō te tuku raraunga tere-tiketike).

RFID: te hangarau matua o te tautuhi atamai

Ka whakamahia e te RFID (tohu auau reo irirangi) ngā ngaru hikohiko me ngā maramara iti hei whakatutuki i te tautuhi aunoa, ā, e whakamahia whānuitia ana i roto i te manatoko tuakiri, te whakahaere ratonga kawe, te ahuwhenua me te whakatipu kararehe, te utu kawe waka me ētahi atu mara. Ahakoa he uaua te hangarau RFID pēnei i te utu me te paerewa, nā tōna ngāwari me tōna whai huatanga kua whakatairanga i te whanaketanga o te whakahaere atamai.

Te whānuitanga o te whakamahinga o te hangarau RF

He kanapa te hangarau RF i roto i ngā mara o te whakawhitiwhiti kōrero ahokore, te whakawhitiwhiti kōrero amiorangi, te kimi radar, te tātaritanga hauora me te whakahaere ahumahi. Mai i ngā whatunga WLAN ki ngā hiko-ngakau, mai i te tirotiro i te papa pakanga ki ngā wheketere atamai, kei te whakatairanga te hangarau RF i te ahunga whakamua hangarau me te whakarerekē i tō tātou momo noho.

Ahakoa kei te tū tonu ngā wero o te hangarau RF, me te whanaketanga o te pūtaiao me te hangarau, ka haere tonu tana pakaru i roto i te auahatanga me te kawe mai i ngā mea maha atu mō te heke mai!
