Ubuchwepheshe bemvamisa yomsakazo obungenantambo: ukuhlaziywa kwesimiso kanye nokusetshenziswa kwemikhakha eminingi

I-RF (Radio Frequency) ibhekisela kumaza kagesi anamaza aphakathi kuka-3kHz no-300GHz, adlala indima ebalulekile kwezokuxhumana, i-radar, ukwelashwa, ukulawulwa kwezimboni kanye neminye imikhakha.

Izimiso eziyisisekelo zemvamisa yomsakazo

Amasignali e-RF akhiqizwa ama-oscillator, kanti amagagasi kagesi asebenza ngesivinini esiphezulu ayadluliselwa futhi asatshalaliswe ngama-antenna. Izinhlobo ezivamile zama-antenna zifaka ama-antenna e-dipole, ama-antenna e-horn kanye nama-antenna e-patch, afanelekela izimo ezahlukene zohlelo lokusebenza. Ingxenye yokwamukela ibuyisela isignali ye-RF kulwazi olusebenzisekayo nge-demodulator ukuze kufezwe ukudluliswa kolwazi.

Izindlela zokuhlela nokuguqula imvamisa yomsakazo

Ngokusho kwemvamisa, imvamisa yomsakazo ingahlukaniswa ibe yimvamisa ephansi (njengokuxhumana kokusakaza), imvamisa ephakathi (njengokuxhumana kweselula), kanye nemvamisa ephezulu (njenge-radar kanye nokwelashwa). Izindlela zokushintshashintsha zifaka phakathi i-AM (yokudlulisa ngesivinini esiphansi), i-FM (yokudlulisa ngesivinini esiphakathi) kanye ne-PM (yokudlulisa idatha ngesivinini esiphezulu).

I-RFID: ubuchwepheshe obuyinhloko bokuhlonza okuhlakaniphile

I-RFID (ukuhlonza imvamisa yomsakazo) isebenzisa amaza kagesi kanye nama-microchip ukuze kufezwe ukuhlonza okuzenzakalelayo, futhi isetshenziswa kabanzi ekuqinisekisweni kobunikazi, ukuphathwa kwempahla, ezolimo kanye nokufuya izilwane, ukukhokha ezokuthutha kanye neminye imikhakha. Nakuba ubuchwepheshe be-RFID bubhekene nezinselele ezifana nezindleko kanye nokulinganisa, ukulula nokusebenza kahle kwayo kukhuthaze ukuthuthukiswa kokuphathwa okuhlakaniphile.

Ukusetshenziswa kabanzi kobuchwepheshe be-RF

Ubuchwepheshe be-RF bukhanya emikhakheni yokuxhumana okungenantambo, ukuxhumana ngesathelayithi, ukutholwa kwe-radar, ukuxilongwa kwezokwelapha kanye nokulawulwa kwezimboni. Kusukela kumanethiwekhi e-WLAN kuya kuma-electrocardiographs, kusukela ekuhloleni kwempi kuya kumafektri ahlakaniphile, ubuchwepheshe be-RF bukhuthaza intuthuko yezobuchwepheshe futhi bushintsha indlela yethu yokuphila.

Nakuba ubuchwepheshe be-RF busabhekene nezinselele, ngentuthuko yesayensi nobuchwepheshe, buzoqhubeka nokugqashula emisha futhi bulethe amathuba engeziwe esikhathi esizayo!
