kungani kuthiwa uthi lwerabha
I-antenna iyithuluzi elisetshenziselwa ukwamukela nokudlulisa amaza omsakazo, futhi idlala indima ebalulekile kwezokuxhumana nobuchwepheshe besimanje.Futhi kungani ngezinye izikhathi izimpondo zibizwa ngokuthi “izimpondo zenjoloba”?Igama livela ekubukekeni nasekuphatheni kothi.Izimpondo zenjoloba zivame ukwakhiwa ngerabha...Funda kabanzi -
iyini intambo yesiginali ye-RF
Intambo ye-RF yikhebula elikhethekile elisetshenziselwa ukudlulisa amasignali efrikhwensi yomsakazo.Ivamise ukusetshenziselwa ukuxhuma imishini yomsakazo nezimpondo ukuze udlulise futhi wamukele amasignali omsakazo.Intambo yesiginali ye-RF inokusebenza okuhle kakhulu kokuvikela kanye nezici zokulahlekelwa okuphansi, futhi ingadlulisela ngempumelelo ephezulu yamahhala...Funda kabanzi -
Inzuzo ye-antenna yerabha yangaphandle
I-antenna yerabha yangaphandle I-antenna yerabha yangaphandle iwuhlobo oluvamile lwe-antenna.Ama-antenna enjoloba avame ukusetshenziswa kumaselula, ama-TV, imishini yenethiwekhi engenantambo, ukuzulazula kwezimoto nezinye izinkambu.Ukusebenzisa i-antenna yerabha yangaphandle kunganikeza ukwamukela okungcono kwesignali kanye nemiphumela yokudlulisela, ikakhulukazi...Funda kabanzi -
Incazelo yesixhumi se-Rf
Izixhumi zezintambo ze-Rf zingenye yezindlela eziwusizo nezivamile zokuxhuma amasistimu nezingxenye ze-RF.Isixhumi se-RF coaxial ulayini wokudlulisa i-coaxial ohlanganisa intambo ye-coaxial ye-RF kanye nesixhumi se-RF coaxial esinqamula ekugcineni kwentambo.Izixhumi ze-Rf zihlinzeka ngoxhumano nge...Funda kabanzi -
Incazelo kanye nokusetshenziswa kwe-antenna kazibuthe
Incazelo ye-antenna kazibuthe Ake sikhulume ngokwakheka kwe-antenna kazibuthe, i-antenna evamile emakethe yakhiwa ikakhulukazi: irediyetha ye-antenna, i-sucker enamandla kazibuthe, i-feeder, i-interface ye-antenna yalezi zingcezu ezine 1, i-antenna radiator impahla ayinamabala. ..Funda kabanzi -
Mayelana nothi, lapha ngizokutshela ~
I-antenna, engasetshenziswa ukudlulisa amasignali nokwamukela amasignali, iyahlehliswa, inokufana, futhi ingathathwa njenge-transducer, okuyidivayisi yesixhumi esibonakalayo phakathi kwesekhethi nesikhala.Uma isetshenziselwa ukudlulisa amasignali, amasignali kagesi wemvamisa ephezulu akhiqizwa umthombo wesignali ...Funda kabanzi -
Ungakhetha kanjani i-antenna?I-antenna yangaphakathi, i-antenna yangaphandle, i-antenna yenkomishi yokumunca?
I-antenna yangaphandle I-antenna yangaphandle ingahlukaniswa ibe uthi lwe-omnidirectional kanye ne-antenna yethemu engashintshi kuye nge-Engeli kanye ne-azimuth yenkundla yomthombo wemisebe.Umdwebo wemisebe yasendlini we-antenna ye-omnidirectional Omnidirectional: okungukuthi, kumdwebo ovundlile, umelela kakhulu...Funda kabanzi -
I-Antenna Tv Indoor
Mayelana nothi lwe-TV wonke umuntu alujwayele, khumbula i-TV endala emnyama nemhlophe, iyi-antenna yayo yase ithuthukiswa yaba yi-antenna ye-TV yangaphandle.Kodwa kuze kube manje, ubuchwepheshe be-antenna ye-TV nokuvuthwa okwengeziwe, manje i-antenna ingahlangabezana kakhulu nezidingo zethu ekuphileni, abangane abaningi emakethe ukuze bu ...Funda kabanzi -
I-Wi-Fi 6E isilapha, ukuhlaziywa kwe-spectrum ye-6GHz
Ngengqungquthela ezayo ye-WRC-23 (2023 World Radiocommunication Conference), ingxoxo yokuhlela i-6GHz iya ishuba ekhaya naphesheya.I-6GHz yonke inomkhawulokudonsa ophelele we-1200MHz (5925-7125MHz).Okubangwayo ukuthi kufanele kwabiwe yini i-5G IMTs (njenge-spectrum enelayisense) noma i-Wi-Fi 6E (njengokusebenzisa okungagunyaziwe...Funda kabanzi -
Isimo sokuthuthuka kanye nenkambiso yesikhathi esizayo yemboni yezokuxhumana ye-antenna ngo-2023
Namuhla, imboni yezokuxhumana ithuthuka ngokushesha.Kusukela kumafoni e-BB ngeminyaka yawo-1980 kuya kumafoni ahlakaniphile namuhla, ukuthuthukiswa kwemboni yezokuxhumana yaseShayina sekuthuthukile kusuka ebhizinisini elilula uma kuqhathaniswa nelemiyalezo emifushane ekuqaleni kuya kumasevisi ahlukahlukene afana ne-inthanethi...Funda kabanzi -
