Imbali kunye nomsebenzi wee-antennas ze-cone horn

Imbali yee-antenna ze-tapered horn iqala ekuqaleni kwenkulungwane yama-20. Ii-antenna zokuqala ze-tapered horn zazisetyenziswa kwi-amplifiers nakwiinkqubo zesithethi ukuphucula imitha yemiqondiso yesandi. Ngophuhliso lonxibelelwano olungenazingcingo, ii-antenna ze-conical horn zisetyenziswa kancinci kancinci kwiindawo zerediyo kunye nee-microwave. Iingenelo zayo kwimitha ye-electromagnetic wave kunye nokwamkelwa kwayo zenza ukuba ibe sisakhiwo esibalulekileyo se-antenna. Emva kweminyaka yoo-1950, ngophuhliso olukhawulezileyo lwetekhnoloji yonxibelelwano lwe-microwave, ii-antenna ze-conical horn zaqala ukusetyenziswa kakhulu kwiindawo zomkhosi nezoluntu. Zisetyenziswa kwizicelo ezifana neenkqubo ze-radar, iinkqubo zonxibelelwano, unxibelelwano lwesathelayithi, ukulinganiswa kwerediyo kunye nee-antenna arrays. Uyilo kunye nokulungiswa kwee-antenna ze-tapered horn nazo zifumene uthotho lophando kunye nophuculo. Ukususela kuhlalutyo lokuqala lwethiyori ukuya ekungenisweni kwee-simulations zamanani kunye ne-algorithms yokwenza ngcono, ukusebenza kwee-antenna ze-tapered horn kuyaqhubeka nokuphucuka. Namhlanje, i-antenna ye-tapered horn iye yaba sisakhiwo se-antenna esiqhelekileyo nesisisiseko esisetyenziswa kakhulu kunxibelelwano olungenazingcingo kunye netekhnoloji ye-microwave.
Isebenza ngokuqondisa amaza e-electromagnetic ukusuka kumazibuko amancinci ukuya kumazibuko amakhulu ukuze kufezekiswe impendulo ephezulu kunye ne-wide frequency. Xa i-electromagnetic wave ingena kwi-port encinci ye-antenna ye-tapered horn esuka kumgca wokudlulisela (njenge-coaxial cable), i-electromagnetic wave iqala ukusasazeka kumphezulu wesakhiwo esi-tapered. Njengoko isakhiwo se-conical sikhula kancinci kancinci, amaza e-electromagnetic asasazeka kancinci, enza indawo enkulu yemitha. Olu lwando lwe-geometry lubangela ukuba amaza e-electromagnetic aphume kwi-port enkulu ye-antenna ye-tapered horn. Ngenxa yesimo esikhethekileyo sesakhiwo se-cone, ukuhlukana kwe-beam yamaza e-electromagnetic kwindawo yemitha kuncinci, ngaloo ndlela kubonelela ngenzuzo ephezulu. Umgaqo osebenzayo we-antenna ye-conical horn uxhomekeke ekukhanyeni, ekukhanyeni nasekuphazanyisweni kwamaza e-electromagnetic ngaphakathi kwesakhiwo se-conical. Ezi nkqubo zivumela amaza e-electromagnetic ukuba agxile kwaye asasazeke, okuwavumela ukuba asasazeke ngokufanelekileyo. Ngamafutshane, umgaqo osebenzayo we-antenna ye-conical horn kukukhokela amaza e-electromagnetic ukusuka kwi-port encinci ukuya kwi-port enkulu, ukufikelela kwi-radiation yamaza e-electromagnetic kunye ne-gain ephezulu ngesakhiwo esikhethekileyo se-geometrical. Oku kwenza ii-antenna ze-tapered horn zibe luhlobo olubalulekileyo lwe-antenna kunxibelelwano olungenazingcingo kunye nezicelo ze-microwave.
