Ibhendi ye-Q kunye nebhendi ye-EHF: Ukusetyenziswa kunye namathuba etekhnoloji ye-frequency ephezulu

Ibhendi ye-Q kunye ne-EHF (Extremely High Frequency) zibhendi ezibalulekileyo zefrikhwensi kwi-electromagnetic spectrum, ezineempawu ezizodwa kunye nokusetyenziswa okubanzi.

Ibhendi ye-Q:

I-Q-band idla ngokubhekisa kuluhlu lweefrikhwensi eziphakathi kwe-33 kunye ne-50 GHz, ezikuluhlu lwe-EHF.

Iimpawu zayo eziphambili ziquka:

I-frequency ephezulu: ubude obufutshane bomda, malunga ne-6 ukuya kwi-9 mm.

I-bandwidth ephezulu: ifanelekile ukuhanjiswa kwedatha ngesantya esiphezulu.

Iindawo eziphambili zokusetyenziswa kwe-Q-band zezi:

Unxibelelwano lwesathelayithi: lusetyenziselwa ukunxibelelana phezulu kunye nokudibanisa iinkqubo zesathelayithi ezisebenzisa i-high-throughput (HTS) ukubonelela ngeenkonzo ze-intanethi ezibanzi.

Unxibelelwano lwe-microwave esemhlabeni: lusetyenziselwa ukusasazwa kwedatha kumgama omfutshane nonamandla aphezulu.

I-astronomy yerediyo: isetyenziselwa ukujonga imithombo yerediyo efumaneka rhoqo kwindalo iphela.

I-radar yeemoto: i-radar yomgama omfutshane esetyenziswa kwiinkqubo zoncedo lwabaqhubi eziphambili (i-ADAS).

Ibhendi ye-EHF:

Ibhendi ye-EHF ibhekisa kuluhlu lweefrikhwensi eziphakathi kwe-30 kunye ne-300 GHz kwaye ubude bomda buyi-1 ukuya kwi-10 mm, ngoko ke ikwabizwa ngokuba yi-millimeter wave band.

Iimpawu zayo eziphambili ziquka:

I-Ultra-high frequency: ekwaziyo ukubonelela ngamanani aphezulu kakhulu okudluliselwa kwedatha.

Umqadi omxinwa: ubungakanani obuncinci be-antenna kunye nesikhokelo esinamandla.

Iindawo eziphambili zokusetyenziswa kwebhendi ye-EHF zezi:

Unxibelelwano lwezomkhosi: lusetyenziselwa iinkqubo zonxibelelwano ezineemfuno eziphezulu zobumfihlo, ezifana neenkqubo zeMilstar zomkhosi wase-US kunye neenkqubo ze-Advanced Extremely High Frequency (AEHF).

Unxibelelwano lwesathelayithi: ukubonelela ngeenkonzo ze-broadband kunye nokuxhasa ukuhanjiswa kwedatha ngesantya esiphezulu.

Iinkqubo zerada: zisetyenziselwa iirada zemifanekiso ezinesisombululo esiphezulu kunye neerada zokulawula umlilo.

Uphando lwezenzululwazi: lusetyenziselwa ukufumanisa umoya kunye nokujonga i-astronomy ngerediyo.

Imingeni kunye nophuhliso:

Nangona iibhendi ze-Q-band kunye ne-EHF zinamathuba amaninzi okusetyenziswa, zisajongene nemingeni ethile kwizicelo ezisebenzayo:

Ukuncitshiswa komoya: imiqondiso ephindaphinda kakhulu ichaphazeleka ziimeko zemozulu ezifana nokuncitshiswa kwemvula ngexesha lokusasazeka, nto leyo ebangela ukuncitshiswa kwemiqondiso.

Ubunzima bobuchwephesha: izixhobo ezisebenzisa amaxesha amaninzi zineemfuno eziphezulu zoyilo kunye nokuveliswa kwaye zibiza kakhulu.

Ukuze bahlangabezane nale mingeni, abaphandi baphuhlisa ubuchwepheshe obuphambili bokuguqula kunye nokubhala iikhowudi, kunye nezicwangciso zokwahluka kweendlela ezikrelekrele zokuphucula ukuthembeka kwenkqubo kunye nokukwazi ukulwa nokuphazamiseka.

Isiphelo:

I-Q-band kunye ne-EHF-band zidlala indima ebalulekileyo kunxibelelwano lwanamhlanje, i-radar kunye nophando lwesayensi.

Ngokuhambela phambili kwetekhnoloji, ukusetyenziswa kwezi bhendi zamaza kuya kwandiswa ngakumbi, okubonelela ngamathuba amatsha ophuhliso lweendawo ezahlukeneyo.
