Umlando wama-antenna e-horn uqala emuva ngo-1897, lapho umcwaningi womsakazo uJagadish Chandra Bose enza khona imiklamo yokuhlola yokuqala esebenzisa ama-microwave. Kamuva, u-GC Southworth noWilmer Barrow basungula isakhiwo se-antenna yesimanje ye-horn ngo-1938 ngokulandelana. Kusukela ngaleso sikhathi, imiklamo yama-antenna e-horn ibilokhu ifundwa ukuze kuchazwe amaphethini ayo okukhanya kanye nokusetshenziswa kwawo emikhakheni eyahlukahlukene. Lawa ma-antenna adumile kakhulu emkhakheni wokudluliselwa kwe-waveguide kanye nama-microwave, ngakho-ke avame ukubizwa ngokuthiama-antenna e-microwaveNgakho-ke, lesi sihloko sizohlola ukuthi ama-antenna e-horn asebenza kanjani kanye nokusetshenziswa kwawo emikhakheni eyahlukahlukene.
Iyini i-antenna ye-horn?
A i-antenna yophondoiyi-antenna yokuvula eyenzelwe ngqo amaza e-microwave anomphetho obanzi noma omise okwesimpondo. Lesi sakhiwo sinikeza i-antenna isiqondiso esikhulu, okuvumela isignali ekhishwayo ukuthi idluliselwe kalula emabangeni amade. Ama-antenna e-Horn asebenza kakhulu kumaza e-microwave, ngakho-ke ububanzi bawo bemvamisa buvame ukuba yi-UHF noma i-EHF.
I-antenna yophondo lwe-RFMISO RM-CDPHA618-20 (6-18GHz)
Lawa ma-antenna asetshenziswa njengezimpondo zokudlala ama-antenna amakhulu njenge-parabolic kanye nama-antenna aqondisa isiqondiso. Izinzuzo zawo zifaka phakathi ukulula kokuklama nokulungisa, isilinganiso samagagasi aphansi, ukuqondisa okulinganiselwe, kanye ne-bandwidth ebanzi.
Umklamo kanye nokusebenza kwe-antenna yempondo
Imiklamo ye-antenna yophondo ingasetshenziswa kusetshenziswa ama-waveguides anomumo we-horn ukuze kudluliselwe futhi kwamukelwe amasignali e-microwave emvamisa yomsakazo. Ngokuvamile, asetshenziswa kanye nama-feed e-waveguides kanye namagagasi omsakazo aqondile ukudala imisebe emincane. Ingxenye evuthayo ingaba ngezimo ezahlukahlukene, njengesikwele, esiyindilinga, noma esingunxande. Ukuqinisekisa ukusebenza kahle, usayizi we-antenna kufanele ube mncane ngangokunokwenzeka. Uma ubude be-wavelength bukhulu kakhulu noma usayizi we-horn umncane, i-antenna ngeke isebenze kahle.
Umdwebo wohlaka lwe-antenna yophondo
Ku-antenna yophondo, ingxenye yamandla esigameko ikhishwa emnyango we-waveguide, kuyilapho amanye amandla ebonakala emuva kusukela emnyango ofanayo ngoba umnyango uvulekile, okuholela ekufaneni okungekuhle kwe-impedance phakathi kwesikhala kanye ne-waveguide. Ngaphezu kwalokho, emaphethelweni e-waveguide, i-diffraction ithinta amandla okukhanya kwe-waveguide.
Ukuze kunqotshwe ukushiyeka kwe-waveguide, ukuvulwa kokuphela kuklanywe ngendlela yophondo lwe-electromagnetic. Lokhu kuvumela ukuguquka okubushelelezi phakathi kwesikhala ne-waveguide, okuhlinzeka ngokuqondisa okungcono kwamagagasi omsakazo.
Ngokushintsha i-waveguide njengesakhiwo se-horn, ukungakwazi ukuqhubeka kanye nokuphazamiseka okungu-377 ohm phakathi kwesikhala kanye ne-waveguide kuyasuswa. Lokhu kuthuthukisa ukuqondiswa kanye nenzuzo ye-antenna yokudlulisa ngokunciphisa ukuphambuka emaphethelweni ukuze kunikezwe amandla okuhlasela akhishwa ohlangothini oluya phambili.
Nansi indlela esebenza ngayo i-antenna yophondo: Uma ingxenye eyodwa yomhlahlandlela wamagagasi isivukile, kukhiqizwa insimu yamagnetic. Uma kwenzeka ukusabalala kwe-waveguide, insimu yokusabalala ingalawulwa ngezindonga zomhlahlandlela wamagagasi ukuze insimu ingasabalali ngendlela eyindilinga kodwa ngendlela efana nokusabalala kwesikhala esikhululekile. Uma insimu edlulayo ifika ekugcineni komhlahlandlela wamagagasi, isabalala ngendlela efanayo nasendaweni ekhululekile, ngakho-ke kutholakala ingaphambili lomugqa oyisiyingi ekugcineni komhlahlandlela wamagagasi.

Ukusetshenziswa kwe-antenna yophondo
Lawa ma-antenna asetshenziswa kakhulu ocwaningweni lwezinkanyezi kanye nezinhlelo zokusebenza ezisekelwe kuma-microwave. Angasetshenziswa njengezinto zokudla ukuze kulinganiswe amapharamitha e-antenna ahlukene elabhorethri. Kuma-frequency e-microwave, lawa ma-antenna angasetshenziswa uma nje ene-gain ephakathi nendawo. Ukuze kufezwe ukusebenza kwe-gain ephakathi nendawo, usayizi we-antenna yophondo kumele ube mkhulu. Lezi zinhlobo zama-antenna zifanele amakhamera ejubane ukuze kugwenywe ukuphazamiseka kwempendulo yokukhanya edingekayo. Ama-reflector e-parabolic angavuselelwa yizinto zokudla ezifana nama-antenna ophondo, ngaleyo ndlela akhanyise ama-reflector ngokusebenzisa isiqondiso esiphezulu asinikezayo.
