Imbali yeempondo zeempondo isukela ngo-1897, xa umphandi kanomathotholo u-Jagadish Chandra Bose wayeqhuba uyilo lovavanyo lobuvulindlela esebenzisa ii-microwaves.Kamva, uGC Southworth kunye noWilmer Barrow baqulunqa ubume be-eriyali yempondo yanamhlanje ngo-1938 ngokulandelelanayo.Ukusukela ngoko, uyilo lwe-eriyali yeempondo luye lwaphononongwa ngokuqhubekayo ukucacisa iipateni zabo zemitha kunye nokusetyenziswa kwiinkalo ezahlukeneyo.Ezi antenna zidume kakhulu kwintsimi yokuhanjiswa kwe-waveguide kunye nee-microwaves, kungoko zihlala zibizwa ngokuba.ii-eriyali ze-microwave.Ke ngoko, eli nqaku liza kuphonononga ukuba zisebenza njani ii-eriyali zeempondo kunye nokusetyenziswa kwazo kwiinkalo ezahlukeneyo.
Yintoni i-eriyali yophondo?
A i-eriyali yophondoyi-eriyali yokuvula eyilelwe ngokukodwa iifrikhwensi ze-microwave ezinesiphelo esandisiweyo okanye esimile okwephondo.Olu lwakhiwo lunika i-eriyali ngokuthe ngqo ngakumbi, ivumela umqondiso okhutshiweyo ukuba udluliselwe ngokulula kumgama omde.Iimpondo zempondo zisebenza ikakhulu kwii-microwave frequencies, ngoko ke uluhlu lwazo lwamaxesha ludla ngokuba yi-UHF okanye i-EHF.
I-eriyali yophondo lwe-RFMISO RM-CDPHA618-20 (6-18GHz)
Ezi-eriyali zisetyenziswa njengeempondo zesondlo kwii-eriyali ezinkulu ezifana ne-parabolic kunye ne-directional eriyali.Iinzuzo zabo ziquka ukulula koyilo kunye nohlengahlengiso, umlinganiselo ophantsi wamaza amaza, ulwalathiso oluphakathi, kunye ne-bandwidth ebanzi.
Uyilo lwe-eriyali yophondo kunye nokusebenza
Uyilo lwe-eriyali yophondo lunokuphunyezwa kusetyenziswa amaza amaza amile okwephondo ukuhambisa kunye nokufumana imiqondiso yerediyo ye-microwave.Ngokwesiqhelo, zisetyenziswa ngokudityaniswa ne-waveguide feeds kunye namaza erediyo ngqo ukwenza imiqadi emxinwa.Icandelo elivuthayo linokuba neemilo ezahlukahlukeneyo, ezifana nesikwere, i-conical, okanye uxande.Ukuqinisekisa ukusebenza okufanelekileyo, ubukhulu be-antenna kufuneka bube buncinci kangangoko.Ukuba i-wavelength inkulu kakhulu okanye ubukhulu bephondo buncinci, i-eriyali ayiyi kusebenza kakuhle.
Umzobo we-eriyali yophondo
Kwi-eriyali yesigodlo, inxalenye yamandla esiganeko ikhutshwa kumnyango we-waveguide, ngelixa amanye amandla ebonakaliswa ngasemva ukusuka kumnyango omnye kuba umnyango uvulekile, okukhokelela kumdlalo ongemhle wokungaphumeleli phakathi kwendawo kunye nendawo yokungena. umkhombandlela.Ukongezelela, emaphethelweni e-waveguide, i-diffraction ichaphazela amandla omsakazo we-waveguide.
Ukuze unqobe ukusilela kwe-waveguide, isiphelo sokuvula siyilwe ngendlela yophondo lwe-electromagnetic.Oku kuvumela inguqu egudileyo phakathi kwesithuba kunye ne-waveguide, ebonelela ngcono ngokuthe ngqo kumaza erediyo.
Ngokutshintsha i-waveguide njengesakhiwo sophondo, ukungaqhubeki kunye ne-377 ohm impedance phakathi kwendawo kunye ne-waveguide iyapheliswa.Oku kwandisa ukuqondisa kunye nokuzuza kwe-eriyali yokudlulisa ngokunciphisa i-diffraction kwimida ukubonelela amandla esiganeko akhutshwa kwicala eliya phambili.
Nantsi indlela esebenza ngayo i-eriyali yesigodlo: Nje ukuba elinye icala le-waveguide libe nemincili, iveliswa imagnethi.Kwimeko yokusasazwa kwe-waveguide, intsimi yokusabalalisa inokulawulwa ngeendonga ze-waveguide ukuze intsimi ingasasazeki ngendlela engqukuva kodwa ngendlela efana neyokukhulula indawo.Nje ukuba ibala elidlulayo lifikelele esiphelweni se-waveguide, lisasazeke ngendlela efanayo nakwindawo ekhululekileyo, ngoko ke i-wavefront engqukuva ifunyenwe ekupheleni kwe-waveguide.
